Bootstrap Typeerror: Cannot Read Property 'state' of Undefined
JavaScript
Bring Bootstrap's components to life with over a dozen custom jQuery plugins. Easily include them all, or 1 by 1.
Private or compiled
Plugins tin be included individually (using Bootstrap'south private *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).
Using the compiled JavaScript
Both bootstrap.js and bootstrap.min.js incorporate all plugins in a single file. Include just ane.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to cheque for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included earlier the plugin files). Consult our bower.json to see which versions of jQuery are supported.
Data attributes
You can use all Bootstrap plugins purely through the markup API without writing a unmarried line of JavaScript. This is Bootstrap'due south first-course API and should be your get-go consideration when using a plugin.
That said, in some situations information technology may be desirable to turn this functionality off. Therefore, nosotros also provide the ability to disable the data attribute API by unbinding all events on the certificate namespaced with data-api. This looks like this:
$ ( document ). off ( '.data-api' ) Alternatively, to target a specific plugin, just include the plugin's proper noun as a namespace along with the information-api namespace similar this:
$ ( document ). off ( '.warning.data-api' ) Only one plugin per element via data attributes
Don't utilise information attributes from multiple plugins on the same element. For case, a button cannot both have a tooltip and toggle a modal. To accomplish this, apply a wrapping element.
Programmatic API
Nosotros also believe you should be able to employ all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
$ ( '.btn.danger' ). button ( 'toggle' ). addClass ( 'fat' ) All methods should take an optional options object, a cord which targets a item method, or naught (which initiates a plugin with default behavior):
$ ( '#myModal' ). modal () // initialized with defaults $ ( '#myModal' ). modal ({ keyboard : false }) // initialized with no keyboard $ ( '#myModal' ). modal ( 'bear witness' ) // initializes and invokes bear witness immediately Each plugin likewise exposes its raw constructor on a Constructor holding: $.fn.popover.Constructor. If you'd like to become a particular plugin instance, recall it directly from an element: $('[rel="popover"]').data('popover').
Default settings
Y'all tin change the default settings for a plugin by modifying the plugin's Constructor.DEFAULTS object:
$ . fn . modal . Constructor . DEFAULTS . keyboard = false // changes default for the modal plugin's `keyboard` choice to false No conflict
Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, y'all may telephone call .noConflict on the plugin you wish to revert the value of.
var bootstrapButton = $ . fn . button . noConflict () // render $.fn.push button to previously assigned value $ . fn . bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality Events
Bootstrap provides custom events for near plugins' unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. prove) is triggered at the start of an event, and its past participle form (ex. shown) is triggered on the completion of an action.
Equally of 3.0.0, all Bootstrap events are namespaced.
All infinitive events provide preventDefault functionality. This provides the ability to finish the execution of an action before it starts.
$ ( '#myModal' ). on ( 'evidence.bs.modal' , function ( e ) { if ( ! information ) return due east . preventDefault () // stops modal from being shown }) Version numbers
The version of each of Bootstrap'south jQuery plugins tin be accessed via the VERSION property of the plugin'due south constructor. For case, for the tooltip plugin:
$ . fn . tooltip . Constructor . VERSION // => "3.three.7" No special fallbacks when JavaScript is disabled
Bootstrap'southward plugins don't autumn dorsum specially gracefully when JavaScript is disabled. If y'all intendance about the user experience in this example, utilize <noscript> to explain the state of affairs (and how to re-enable JavaScript) to your users, and/or add your own custom fallbacks.
Tertiary-party libraries
Bootstrap does non officially support third-party JavaScript libraries similar Epitome or jQuery UI. Despite .noConflict and namespaced events, there may exist compatibility problems that yous need to fix on your own.
About transitions
For unproblematic transition effects, include transition.js one time aslope the other JS files. If you lot're using the compiled (or minified) bootstrap.js, in that location is no demand to include this—it'south already there.
What's within
Transition.js is a bones helper for transitionEnd events also as a CSS transition emulator. It'southward used by the other plugins to check for CSS transition support and to catch hanging transitions.
Disabling transitions
Transitions can be globally disabled using the following JavaScript snippet, which must come later transition.js (or bootstrap.js or bootstrap.min.js, as the case may be) has loaded:
$ . support . transition = faux Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
Multiple open modals non supported
Exist sure not to open up a modal while another is yet visible. Showing more than i modal at a time requires custom code.
Modal markup placement
E'er attempt to place a modal's HTML lawmaking in a top-level position in your certificate to avoid other components affecting the modal's appearance and/or functionality.
Due to how HTML5 defines its semantics, the autofocus HTML aspect has no effect in Bootstrap modals. To achieve the same effect, employ some custom JavaScript:
$ ( '#myModal' ). on ( 'shown.bs.modal' , function () { $ ( '#myInput' ). focus () }) Examples
Static example
A rendered modal with header, body, and set of actions in the footer.
<div form= "modal fade" tabindex= "-one" role= "dialog" > <div form= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button blazon= "button" course= "close" information-dismiss= "modal" aria-label= "Shut" ><span aria-subconscious= "true" > × </span></button> <h4 course= "modal-title" >Modal championship</h4> </div> <div class= "modal-body" > <p>One fine body… </p> </div> <div class= "modal-footer" > <button type= "button" grade= "btn btn-default" data-dismiss= "modal" >Shut</button> <button type= "button" class= "btn btn-primary" >Save changes</button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Alive demo
Toggle a modal via JavaScript past clicking the button below. It will slide down and fade in from the top of the page.
<!-- Push trigger modal --> <push type= "button" form= "btn btn-primary btn-lg" information-toggle= "modal" data-target= "#myModal" > Launch demo modal </button> <!-- Modal --> <div class= "modal fade" id= "myModal" tabindex= "-1" function= "dialog" aria-labelledby= "myModalLabel" > <div class= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button type= "button" class= "close" data-dismiss= "modal" aria-label= "Shut" ><span aria-hidden= "true" > × </span></button> <h4 class= "modal-title" id= "myModalLabel" >Modal title</h4> </div> <div class= "modal-torso" > ... </div> <div class= "modal-footer" > <button type= "button" course= "btn btn-default" data-dismiss= "modal" >Close</button> <push button blazon= "push button" grade= "btn btn-primary" >Relieve changes</button> </div> </div> </div> </div> Brand modals accessible
Be sure to add function="dialog" and aria-labelledby="...", referencing the modal championship, to .modal, and function="document" to the .modal-dialog itself.
Additionally, you may give a description of your modal dialog with aria-describedby on .modal.
Embedding YouTube videos
Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically cease playback and more. See this helpful Stack Overflow post for more information.
Optional sizes
Modals have two optional sizes, bachelor via modifier classes to be placed on a .modal-dialog.
<!-- Large modal --> <push type= "push" grade= "btn btn-main" information-toggle= "modal" information-target= ".bs-example-modal-lg" >Large modal</button> <div class= "modal fade bs-instance-modal-lg" tabindex= "-1" office= "dialog" aria-labelledby= "myLargeModalLabel" > <div class= "modal-dialog modal-lg" role= "document" > <div class= "modal-content" > ... </div> </div> </div> <!-- Pocket-size modal --> <button type= "push button" class= "btn btn-primary" data-toggle= "modal" data-target= ".bs-example-modal-sm" >Pocket-sized modal</button> <div grade= "modal fade bs-instance-modal-sm" tabindex= "-1" office= "dialog" aria-labelledby= "mySmallModalLabel" > <div course= "modal-dialog modal-sm" office= "document" > <div grade= "modal-content" > ... </div> </div> </div> Remove animation
For modals that simply appear rather than fade in to view, remove the .fade course from your modal markup.
<div form= "modal" tabindex= "-1" role= "dialog" aria-labelledby= "..." > ... </div> Using the grid arrangement
To accept advantage of the Bootstrap grid system within a modal, but nest .rows inside the .modal-body and and then utilise the normal grid organisation classes.
<div form= "modal fade" tabindex= "-1" role= "dialog" aria-labelledby= "gridSystemModalLabel" > <div class= "modal-dialog" role= "document" > <div class= "modal-content" > <div class= "modal-header" > <button type= "push button" class= "shut" information-dismiss= "modal" aria-label= "Shut" ><span aria-hidden= "true" > × </span></button> <h4 class= "modal-title" id= "gridSystemModalLabel" >Modal title</h4> </div> <div class= "modal-body" > <div form= "row" > <div grade= "col-md-four" >.col-md-4</div> <div class= "col-md-4 col-md-beginning-4" >.col-physician-4 .col-md-commencement-4</div> </div> <div class= "row" > <div form= "col-md-3 col-md-offset-iii" >.col-md-3 .col-md-offset-3</div> <div form= "col-md-two col-md-offset-iv" >.col-md-2 .col-dr.-offset-4</div> </div> <div grade= "row" > <div course= "col-dr.-6 col-doc-commencement-3" >.col-dr.-6 .col-md-offset-3</div> </div> <div class= "row" > <div class= "col-sm-9" > Level 1: .col-sm-9 <div class= "row" > <div course= "col-xs-8 col-sm-6" > Level two: .col-xs-8 .col-sm-6 </div> <div class= "col-xs-four col-sm-half dozen" > Level 2: .col-xs-four .col-sm-6 </div> </div> </div> </div> </div> <div class= "modal-footer" > <button type= "button" form= "btn btn-default" data-dismiss= "modal" >Close</button> <button type= "button" class= "btn btn-chief" >Relieve changes</button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Have a bunch of buttons that all trigger the same modal, just with slightly unlike contents? Use event.relatedTarget and HTML data-* attributes (perhaps via jQuery) to vary the contents of the modal depending on which push was clicked. See the Modal Events docs for details on relatedTarget,

Nosotros'll apply jQuery here, but you could utilise a data binding library or other methods instead. var modal = $ ( this ) modal . discover ( '.modal-title' ). text ( 'New bulletin to ' + recipient ) modal . find ( '.modal-trunk input' ). val ( recipient ) }) Usage
The modal plugin toggles your subconscious content on demand, via information attributes or JavaScript. Information technology also adds .modal-open up to the <body> to override default scrolling behavior and generates a .modal-backdrop to provide a click expanse for dismissing shown modals when clicking outside the modal.
Via data attributes
Activate a modal without writing JavaScript. Gear up data-toggle="modal" on a controller chemical element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.
<button blazon= "push button" data-toggle= "modal" data-target= "#myModal" >Launch modal</button> Via JavaScript
Telephone call a modal with id myModal with a single line of JavaScript:
$ ( '#myModal' ). modal ( options ) Options
Options can be passed via data attributes or JavaScript. For data attributes, suspend the pick name to data-, every bit in information-backdrop="".
| Name | blazon | default | description |
|---|---|---|---|
| properties | boolean or the string 'static' | true | Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click. |
| keyboard | boolean | truthful | Closes the modal when escape fundamental is pressed |
| testify | boolean | true | Shows the modal when initialized. |
| remote | path | false | This selection is deprecated since v3.iii.0 and has been removed in v4. Nosotros recommend instead using client-side templating or a information binding framework, or calling jQuery.load yourself. If a remote URL is provided, content will be loaded once via jQuery'south |
Methods
.modal(options)
Activates your content equally a modal. Accepts an optional options object.
$ ( '#myModal' ). modal ({ keyboard : false }) .modal('toggle')
Manually toggles a modal. Returns to the caller before the modal has really been shown or subconscious (i.east. earlier the shown.bs.modal or hidden.bs.modal outcome occurs).
$ ( '#myModal' ). modal ( 'toggle' ) .modal('bear witness')
Manually opens a modal. Returns to the caller before the modal has really been shown (i.e. before the shown.bs.modal outcome occurs).
$ ( '#myModal' ). modal ( 'show' ) .modal('hide')
Manually hides a modal. Returns to the caller before the modal has actually been subconscious (i.e. before the hidden.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'hide' ) .modal('handleUpdate')
Readjusts the modal's positioning to counter a scrollbar in case ane should announced, which would make the modal bound to the left.
Only needed when the height of the modal changes while it is open.
$ ( '#myModal' ). modal ( 'handleUpdate' ) Events
Bootstrap's modal course exposes a few events for hooking into modal functionality.
All modal events are fired at the modal itself (i.e. at the <div class="modal">).
| Event Type | Description |
|---|---|
| show.bs.modal | This event fires immediately when the show instance method is called. If caused by a click, the clicked element is bachelor as the relatedTarget property of the effect. |
| shown.bs.modal | This result is fired when the modal has been made visible to the user (will expect for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event. |
| hibernate.bs.modal | This event is fired immediately when the hibernate instance method has been called. |
| hidden.bs.modal | This upshot is fired when the modal has finished existence hidden from the user (will wait for CSS transitions to consummate). |
| loaded.bs.modal | This effect is fired when the modal has loaded content using the remote option. |
$ ( '#myModal' ). on ( 'subconscious.bs.modal' , role ( e ) { // do something... }) Examples
Add together dropdown menus to nearly annihilation with this uncomplicated plugin, including the navbar, tabs, and pills.
Within a navbar
Inside pills
Usage
Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) past toggling the .open form on the parent list particular.
On mobile devices, opening a dropdown adds a .dropdown-backdrop equally a tap area for closing dropdown menus when tapping outside the card, a requirement for proper iOS back up. This means that switching from an open dropdown bill of fare to a different dropdown carte du jour requires an extra tap on mobile.
Note: The data-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, and so information technology's a good idea to always use it.
Via information attributes
Add information-toggle="dropdown" to a link or button to toggle a dropdown.
<div grade= "dropdown" > <button id= "dLabel" blazon= "push button" data-toggle= "dropdown" aria-haspopup= "true" aria-expanded= "simulated" > Dropdown trigger <span class= "caret" ></span> </button> <ul class= "dropdown-bill of fare" aria-labelledby= "dLabel" > ... </ul> </div> To proceed URLs intact with link buttons, use the information-target attribute instead of href="#".
<div class= "dropdown" > <a id= "dLabel" data-target= "#" href= "http://case.com/" information-toggle= "dropdown" role= "button" aria-haspopup= "true" aria-expanded= "false" > Dropdown trigger <bridge class= "caret" ></bridge> </a> <ul class= "dropdown-card" aria-labelledby= "dLabel" > ... </ul> </div> Via JavaScript
Call the dropdowns via JavaScript:
$ ( '.dropdown-toggle' ). dropdown () data-toggle="dropdown" still required
Regardless of whether you lot telephone call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown" is always required to exist nowadays on the dropdown's trigger chemical element.
Options
None
Methods
$().dropdown('toggle')
Toggles the dropdown carte of a given navbar or tabbed navigation.
Events
All dropdown events are fired at the .dropdown-carte's parent element.
All dropdown events take a relatedTarget property, whose value is the toggling anchor element.
| Event Type | Description |
|---|---|
| testify.bs.dropdown | This upshot fires immediately when the show example method is chosen. |
| shown.bs.dropdown | This event is fired when the dropdown has been made visible to the user (will wait for CSS transitions, to complete). |
| hibernate.bs.dropdown | This event is fired immediately when the hide instance method has been chosen. |
| hidden.bs.dropdown | This upshot is fired when the dropdown has finished being subconscious from the user (will wait for CSS transitions, to consummate). |
$ ( '#myDropdown' ). on ( 'testify.bs.dropdown' , function () { // do something… }) The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Whorl the expanse below the navbar and sentinel the active class alter. The dropdown sub items will exist highlighted likewise.
Requires relative positioning
No matter the implementation method, scrollspy requires the utilise of position: relative; on the element y'all're spying on. In most cases this is the <torso>. When scrollspying on elements other than the <torso>, be certain to have a height gear up and overflow-y: scroll; practical.
Via information attributes
To easily add scrollspy behavior to your topbar navigation, add data-spy="whorl" to the chemical element you want to spy on (most typically this would be the <body>). And then add the information-target attribute with the ID or class of the parent element of whatever Bootstrap .nav component.
torso { position : relative ; } <trunk data-spy= "scroll" information-target= "#navbar-example" > ... <div id= "navbar-example" > <ul course= "nav nav-tabs" role= "tablist" > ... </ul> </div> ... </trunk> Via JavaScript
After adding position: relative; in your CSS, call the scrollspy via JavaScript:
$ ( 'body' ). scrollspy ({ target : '#navbar-example' }) Methods
.scrollspy('refresh')
When using scrollspy in conjunction with calculation or removing of elements from the DOM, you lot'll need to call the refresh method like so:
$ ( '[information-spy="roll"]' ). each ( function () { var $spy = $ ( this ). scrollspy ( 'refresh' ) }) Options
Options tin exist passed via information attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".
| Name | type | default | description |
|---|---|---|---|
| offset | number | x | Pixels to first from top when computing position of ringlet. |
Events
| Event Blazon | Clarification |
|---|---|
| actuate.bs.scrollspy | This event fires whenever a new item becomes activated by the scrollspy. |
$ ( '#myScrollspy' ). on ( 'actuate.bs.scrollspy' , office () { // practice something… }) Example tabs
Add quick, dynamic tab functionality to transition through panes of local content, even via dropdown menus. Nested tabs are non supported.

Usage
Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
$ ( '#myTabs a' ). click ( role ( e ) { e . preventDefault () $ ( this ). tab ( 'show' ) }) You tin activate individual tabs in several ways:
$ ( '#myTabs a[href="#profile"]' ). tab ( 'show' ) // Select tab past proper name $ ( '#myTabs a:first' ). tab ( 'show' ) // Select first tab $ ( '#myTabs a:last' ). tab ( 'show' ) // Select last tab $ ( '#myTabs li:eq(2) a' ). tab ( 'show' ) // Select third tab (0-indexed) Markup
Y'all can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or information-toggle="pill" on an element. Calculation the nav and nav-tabs classes to the tab ul will utilize the Bootstrap tab styling, while calculation the nav and nav-pills classes will apply pill styling.
<div> <!-- Nav tabs --> <ul form= "nav nav-tabs" part= "tablist" > <li role= "presentation" form= "active" ><a href= "#home" aria-controls= "domicile" role= "tab" data-toggle= "tab" >Home</a></li> <li role= "presentation" ><a href= "#profile" aria-controls= "profile" office= "tab" data-toggle= "tab" >Contour</a></li> <li office= "presentation" ><a href= "#messages" aria-controls= "messages" office= "tab" data-toggle= "tab" >Messages</a></li> <li office= "presentation" ><a href= "#settings" aria-controls= "settings" role= "tab" data-toggle= "tab" >Settings</a></li> </ul> <!-- Tab panes --> <div class= "tab-content" > <div role= "tabpanel" class= "tab-pane active" id= "home" >...</div> <div part= "tabpanel" class= "tab-pane" id= "profile" >...</div> <div role= "tabpanel" class= "tab-pane" id= "letters" >...</div> <div role= "tabpanel" form= "tab-pane" id= "settings" >...</div> </div> </div> Fade effect
To brand tabs fade in, add .fade to each .tab-pane. The offset tab pane must also have .in to make the initial content visible.
<div class= "tab-content" > <div role= "tabpanel" class= "tab-pane fade in active" id= "dwelling" >...</div> <div role= "tabpanel" class= "tab-pane fade" id= "profile" >...</div> <div function= "tabpanel" class= "tab-pane fade" id= "messages" >...</div> <div role= "tabpanel" class= "tab-pane fade" id= "settings" >...</div> </div> Methods
$().tab
Activates a tab element and content container. Tab should accept either a information-target or an href targeting a container node in the DOM. In the above examples, the tabs are the <a>s with information-toggle="tab" attributes.
.tab('testify')
Selects the given tab and shows its associated content. Whatever other tab that was previously selected becomes unselected and its associated content is subconscious. Returns to the caller before the tab pane has really been shown (i.eastward. before the shown.bs.tab event occurs).
$ ( '#someTab' ). tab ( 'testify' ) Events
When showing a new tab, the events burn down in the following order:
-
hide.bs.tab(on the electric current active tab) -
show.bs.tab(on the to-exist-shown tab) -
subconscious.bs.tab(on the previous active tab, the aforementioned one as for thehide.bs.tabevent) -
shown.bs.tab(on the newly-agile but-shown tab, the same 1 equally for theshow.bs.tabevent)
If no tab was already active, then the hide.bs.tab and hidden.bs.tab events volition not be fired.
| Event Type | Description |
|---|---|
| show.bs.tab | This event fires on tab show, simply earlier the new tab has been shown. Use event.target and result.relatedTarget to target the active tab and the previous active tab (if available) respectively. |
| shown.bs.tab | This event fires on tab show after a tab has been shown. Use outcome.target and event.relatedTarget to target the active tab and the previous agile tab (if available) respectively. |
| hide.bs.tab | This event fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use consequence.target and event.relatedTarget to target the current active tab and the new soon-to-be-active tab, respectively. |
| subconscious.bs.tab | This consequence fires after a new tab is shown (and thus the previous agile tab is subconscious). Apply event.target and event.relatedTarget to target the previous agile tab and the new agile tab, respectively. |
$ ( 'a[data-toggle="tab"]' ). on ( 'shown.bs.tab' , function ( e ) { e . target // newly activated tab due east . relatedTarget // previous agile tab }) Inspired past the first-class jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and information-attributes for local title storage.
Tooltips with zero-length titles are never displayed.

Static tooltip
4 options are available: top, right, bottom, and left aligned.
4 directions
<push button blazon= "button" class= "btn btn-default" information-toggle= "tooltip" information-placement= "left" title= "Tooltip on left" >Tooltip on left</button> <button type= "button" form= "btn btn-default" data-toggle= "tooltip" information-placement= "pinnacle" championship= "Tooltip on height" >Tooltip on top</push button> <button type= "push" course= "btn btn-default" data-toggle= "tooltip" data-placement= "bottom" title= "Tooltip on bottom" >Tooltip on bottom</button> <push button type= "button" form= "btn btn-default" data-toggle= "tooltip" data-placement= "right" title= "Tooltip on right" >Tooltip on right</push> The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
$ ( '#example' ). tooltip ( options ) Markup
The required markup for a tooltip is only a information attribute and title on the HTML element yous wish to have a tooltip. The generated markup of a tooltip is rather simple, though information technology does crave a position (past default, set to height by the plugin).
<!-- HTML to write --> <a href= "#" data-toggle= "tooltip" title= "Some tooltip text!" >Hover over me</a> <!-- Generated markup by the plugin --> <div class= "tooltip tiptop" part= "tooltip" > <div form= "tooltip-pointer" ></div> <div class= "tooltip-inner" > Some tooltip text! </div> </div> Options
Options tin exist passed via data attributes or JavaScript. For data attributes, append the option proper name to information-, as in data-blitheness="".

Methods
$().tooltip(options)
Attaches a tooltip handler to an chemical element collection.
.tooltip('show')
Reveals an element'due south tooltip. Returns to the caller before the tooltip has really been shown (i.e. earlier the shown.bs.tooltip consequence occurs). This is considered a "transmission" triggering of the tooltip. Tooltips with nix-length titles are never displayed.
$ ( '#chemical element' ). tooltip ( 'testify' ) .tooltip('hibernate')
Hides an element's tooltip. Returns to the caller earlier the tooltip has actually been hidden (i.due east. before the subconscious.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$ ( '#chemical element' ). tooltip ( 'hide' ) .tooltip('toggle')
Toggles an chemical element's tooltip. Returns to the caller before the tooltip has actually been shown or hidden (i.e. before the shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$ ( '#element' ). tooltip ( 'toggle' ) .tooltip('destroy')
Hides and destroys an chemical element's tooltip. Tooltips that use delegation (which are created using the selector selection) cannot exist individually destroyed on descendant trigger elements.
$ ( '#element' ). tooltip ( 'destroy' ) Events
| Event Type | Description |
|---|---|
| evidence.bs.tooltip | This event fires immediately when the testify case method is called. |
| shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (volition wait for CSS transitions to complete). |
| hide.bs.tooltip | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.tooltip | This issue is fired when the tooltip has finished being subconscious from the user (will wait for CSS transitions to complete). |
| inserted.bs.tooltip | This event is fired after the show.bs.tooltip upshot when the tooltip template has been added to the DOM. |
$ ( '#myTooltip' ). on ( 'hidden.bs.tooltip' , role () { // do something… }) Add pocket-size overlays of content, like those on the iPad, to any element for housing secondary information.
Popovers whose both title and content are cipher-length are never displayed.
Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
One mode to initialize all popovers on a page would be to select them past their data-toggle attribute:
$ ( function () { $ ( '[information-toggle="popover"]' ). popover () }) Popovers in push button groups, input groups, and tables require special setting
When using popovers on elements within a .btn-grouping or an .input-group, or on table-related elements (<td>, <th>, <tr>, <thead>, <tbody>, <tfoot>), you'll have to specify the selection container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).
Popovers on disabled elements require wrapper elements
To add a popover to a disabled or .disabled element, put the element within of a <div> and apply the popover to that <div> instead.
Multiple-line links
Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.
Examples
Static popover
Four options are available: top, correct, bottom, and left aligned.
Popover superlative
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover right
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover bottom
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover left
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Use the focus trigger to dismiss popovers on the next click that the user makes.
Specific markup required for dismiss-on-next-click
For proper cantankerous-browser and cantankerous-platform behavior, you must use the <a> tag, not the <push button> tag, and you besides must include the role="button" and tabindex attributes.
<a tabindex= "0" course= "btn btn-lg btn-danger" function= "button" data-toggle= "popover" data-trigger= "focus" title= "Dismissible popover" data-content= "And here's some amazing content. It's very engaging. Right?" >Dismissible popover</a> Usage

Methods
$().popover(options)
Initializes popovers for an chemical element collection.
.popover('show')
Reveals an element'south popover. Returns to the caller before the popover has actually been shown (i.e. earlier the shown.bs.popover event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are goose egg-length are never displayed.
$ ( '#element' ). popover ( 'prove' ) .popover('hide')
Hides an element's popover. Returns to the caller earlier the popover has actually been hidden (i.e. before the hidden.bs.popover event occurs). This is considered a "manual" triggering of the popover.
$ ( '#element' ). popover ( 'hide' ) .popover('toggle')
Toggles an chemical element's popover. Returns to the caller before the popover has actually been shown or hidden (i.e. earlier the shown.bs.popover or hidden.bs.popover effect occurs). This is considered a "transmission" triggering of the popover.
$ ( '#element' ). popover ( 'toggle' ) .popover('destroy')
Hides and destroys an element'south popover. Popovers that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$ ( '#element' ). popover ( 'destroy' ) Events
| Upshot Blazon | Description |
|---|---|
| show.bs.popover | This outcome fires immediately when the show instance method is called. |
| shown.bs.popover | This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete). |

$ ( '#myPopover' ). on ( 'hidden.bs.popover' , function () { // practise something… }) Example alerts
Add dismiss functionality to all alarm letters with this plugin.
When using a .shut button, it must be the first child of the .alert-dismissible and no text content may come before it in the markup.
Usage
Simply add data-dismiss="alert" to your close push button to automatically give an alarm close functionality. Endmost an alert removes it from the DOM.
<button blazon= "button" class= "close" information-dismiss= "alert" aria-label= "Close" > <bridge aria-hidden= "truthful" > × </span> </button> To have your alerts use animation when closing, brand certain they have the .fade and .in classes already applied to them.
Methods
$().alert()
Makes an alert listen for click events on descendant elements which have the information-dismiss="warning" aspect. (Not necessary when using the data-api'south auto-initialization.)
$().alert('shut')
Closes an alert by removing it from the DOM. If the .fade and .in classes are present on the element, the warning will fade out before it is removed.
Events
Bootstrap'southward alert plugin exposes a few events for hooking into warning functionality.
| Event Type | Clarification |
|---|---|
| close.bs.alert | This event fires immediately when the shut instance method is called. |
| closed.bs.alert | This event is fired when the alert has been closed (will await for CSS transitions to complete). |
$ ( '#myAlert' ). on ( 'closed.bs.alarm' , part () { // do something… }) Do more with buttons. Command push states or create groups of buttons for more components similar toolbars.
Stateful
Add together data-loading-text="Loading..." to use a loading country on a button.
This feature is deprecated since v3.three.five and has been removed in v4.
Use whichever country you lot like!
For the sake of this demonstration, we are using data-loading-text and $().button('loading'), but that's not the only state you can employ. Run into more on this below in the $().button(string) documentation.
<button blazon= "button" id= "myButton" data-loading-text= "Loading..." class= "btn btn-master" autocomplete= "off" > Loading land </push> <script> $ ( '#myButton' ). on ( 'click' , office () { var $btn = $ ( this ). button ( 'loading' ) // business concern logic... $btn . button ( 'reset' ) }) </script> Single toggle
Add data-toggle="push button" to activate toggling on a single button.
Pre-toggled buttons need .agile and aria-pressed="true"
For pre-toggled buttons, yous must add together the .active grade and the aria-pressed="true" attribute to the button yourself.
<button type= "button" class= "btn btn-primary" information-toggle= "button" aria-pressed= "imitation" autocomplete= "off" > Single toggle </button> Checkbox / Radio
Add information-toggle="buttons" to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.
Preselected options demand .active
For preselected options, you must add the .active class to the input'south label yourself.
Visual checked state only updated on click
If the checked state of a checkbox button is updated without firing a click result on the button (east.yard. via <input blazon="reset"> or via setting the checked holding of the input), you will demand to toggle the .active class on the input's label yourself.
<div grade= "btn-group" data-toggle= "buttons" > <characterization class= "btn btn-primary active" > <input type= "checkbox" autocomplete= "off" checked > Checkbox ane (pre-checked) </label> <label class= "btn btn-primary" > <input type= "checkbox" autocomplete= "off" > Checkbox ii </label> <label form= "btn btn-primary" > <input type= "checkbox" autocomplete= "off" > Checkbox 3 </label> </div>
<div form= "btn-group" data-toggle= "buttons" > <label class= "btn btn-primary active" > <input blazon= "radio" name= "options" id= "option1" autocomplete= "off" checked > Radio 1 (preselected) </label> <label grade= "btn btn-primary" > <input blazon= "radio" name= "options" id= "option2" autocomplete= "off" > Radio 2 </label> <label class= "btn btn-main" > <input type= "radio" name= "options" id= "option3" autocomplete= "off" > Radio 3 </label> </div> Methods
$().button('toggle')
Toggles push state. Gives the button the appearance that it has been activated.
$().push button('reset')
Resets button country - swaps text to original text. This method is asynchronous and returns earlier the resetting has actually completed.
$().button(string)
Swaps text to any data defined text state.
<button type= "push button" id= "myStateButton" information-complete-text= "finished!" class= "btn btn-principal" autocomplete= "off" > ... </push button> <script> $ ( '#myStateButton' ). on ( 'click' , function () { $ ( this ). button ( 'complete' ) // button text will be "finished!" }) </script> Flexible plugin that utilizes a handful of classes for easy toggle beliefs.
Plugin dependency
Collapse requires the transitions plugin to be included in your version of Bootstrap.
Example
Click the buttons below to show and hide another element via class changes:
-
.collapsehides content -
.collapsingis applied during transitions -
.collapse.inshows content
You can apply a link with the href aspect, or a push button with the information-target attribute. In both cases, the data-toggle="collapse" is required.

Make aggrandize/collapse controls accessible
Exist sure to add together aria-expanded to the command element. This aspect explicitly defines the current state of the collapsible chemical element to screen readers and similar assistive technologies. If the collapsible element is airtight by default, it should have a value of aria-expanded="false". If you've set the collapsible element to be open past default using the in class, set aria-expanded="truthful" on the command instead. The plugin volition automatically toggle this aspect based on whether or not the collapsible element has been opened or airtight.
Additionally, if your control element is targeting a single collapsible chemical element – i.due east. the data-target attribute is pointing to an id selector – you may add an additional aria-controls attribute to the control element, containing the id of the collapsible chemical element. Mod screen readers and similar assistive technologies make use of this attribute to provide users with boosted shortcuts to navigate directly to the collapsible element itself.
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
-
.collapsehides the content -
.plummet.inshows the content -
.collapsingis added when the transition starts, and removed when it finishes
These classes can be establish in component-animations.less.
Via data attributes
Simply add data-toggle="collapse" and a data-target to the chemical element to automatically assign control of a collapsible chemical element. The data-target attribute accepts a CSS selector to apply the collapse to. Exist certain to add the class collapse to the collapsible element. If yous'd similar information technology to default open, add together the additional class in.
To add accordion-like grouping management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to see this in action.
Via JavaScript
Enable manually with:
$ ( '.collapse' ). collapse () Options
Options can be passed via information attributes or JavaScript. For data attributes, append the choice name to data-, as in information-parent="".
| Proper name | type | default | description |
|---|---|---|---|
| parent | selector | false | If a selector is provided, then all collapsible elements under the specified parent will exist closed when this collapsible item is shown. (similar to traditional piano accordion beliefs - this is dependent on the panel grade) |
| toggle | boolean | truthful | Toggles the collapsible element on invocation |
Methods
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object.
$ ( '#myCollapsible' ). collapse ({ toggle : imitation }) .collapse('toggle')
Toggles a collapsible element to shown or hidden. Returns to the caller before the collapsible element has really been shown or subconscious (i.e. before the shown.bs.plummet or hidden.bs.plummet outcome occurs).
.collapse('evidence')
Shows a collapsible element. Returns to the caller before the collapsible element has actually been shown (i.e. before the shown.bs.collapse result occurs).
.collapse('hibernate')
Hides a collapsible element. Returns to the caller earlier the collapsible chemical element has actually been subconscious (i.e. before the subconscious.bs.plummet upshot occurs).
Events
Bootstrap's collapse class exposes a few events for hooking into collapse functionality.
| Event Type | Description |
|---|---|
| show.bs.collapse | This event fires immediately when the show instance method is chosen. |
| shown.bs.collapse | This effect is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.collapse | This upshot is fired immediately when the hide method has been called. |
| hidden.bs.plummet | This event is fired when a collapse element has been hidden from the user (will look for CSS transitions to consummate). |
$ ( '#myCollapsible' ). on ( 'hidden.bs.collapse' , office () { // practise something… }) A slideshow component for cycling through elements, like a carousel. Nested carousels are not supported.
Examples
<div id= "carousel-example-generic" course= "carousel slide" data-ride= "carousel" > <!-- Indicators --> <ol class= "carousel-indicators" > <li information-target= "#carousel-case-generic" information-slide-to= "0" course= "active" ></li> <li data-target= "#carousel-instance-generic" data-slide-to= "1" ></li> <li data-target= "#carousel-instance-generic" data-slide-to= "2" ></li> </ol> <!-- Wrapper for slides --> <div course= "carousel-inner" role= "listbox" > <div class= "item active" > <img src= "..." alt= "..." > <div class= "carousel-caption" > ... </div> </div> <div class= "item" > <img src= "..." alt= "..." > <div course= "carousel-explanation" > ... </div> </div> ... </div> <!-- Controls --> <a form= "left carousel-control" href= "#carousel-example-generic" role= "button" data-slide= "prev" > <span class= "glyphicon glyphicon-chevron-left" aria-hidden= "true" ></span> <span class= "sr-simply" >Previous</span> </a> <a course= "right carousel-control" href= "#carousel-case-generic" role= "push" information-slide= "adjacent" > <span class= "glyphicon glyphicon-chevron-right" aria-subconscious= "truthful" ></span> <span class= "sr-merely" >Next</span> </a> </div> Accessibility upshot
The carousel component is generally not compliant with accessibility standards. If you lot need to be compliant, delight consider other options for presenting your content.
Transition animations not supported in Internet Explorer 8 & nine
Bootstrap exclusively uses CSS3 for its animations, only Internet Explorer viii & 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We accept intentionally decided non to include jQuery-based fallbacks for the transitions.
Initial agile element required
The .active course needs to be added to one of the slides. Otherwise, the carousel will not exist visible.
Glyphicon icons not necessary
The .glyphicon .glyphicon-chevron-left and .glyphicon .glyphicon-chevron-right classes are not necessarily needed for the controls. Bootstrap provides .icon-prev and .icon-next as apparently unicode alternatives.
Optional captions
Add captions to your slides easily with the .carousel-caption element within whatsoever .item. Place just about whatever optional HTML within there and information technology will exist automatically aligned and formatted.
Get-go slide label
Nulla vitae elit libero, a pharetra augue mollis interdum.
Second slide label

Previous Next
<div class= "item" > <img src= "..." alt= "..." > <div class= "carousel-caption" > <h3>...</h3> <p>...</p> </div> </div> Usage
Multiple carousels
Carousels crave the utilise of an id on the outermost container (the .carousel) for carousel controls to office properly. When adding multiple carousels, or when changing a carousel'southward id, be sure to update the relevant controls.
Via data attributes
Use data attributes to easily control the position of the carousel. data-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, use data-slide-to to laissez passer a raw slide index to the carousel information-slide-to="ii", which shifts the slide position to a item alphabetize beginning with 0.
The data-ride="carousel" attribute is used to mark a carousel as animating starting at folio load. Information technology cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the same carousel.

relatedTarget: The DOM element that is beingness slid into identify as the active item.
All carousel events are fired at the carousel itself (i.eastward. at the <div form="carousel">).
| Event Type | Description |
|---|---|
| slide.bs.carousel | This result fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$ ( '#myCarousel' ). on ( 'slide.bs.carousel' , function () { // exercise something… }) Example
The affix plugin toggles position: fixed; on and off, emulating the effect plant with position: sticky;. The subnavigation on the correct is a live demo of the braze plugin.
Usage
Use the affix plugin via data attributes or manually with your ain JavaScript. In both situations, you must provide CSS for the positioning and width of your affixed content.
Note: Practise not use the affix plugin on an element contained in a relatively positioned element, such equally a pulled or pushed column, due to a Safari rendering bug.
Positioning via CSS
The braze plugin toggles betwixt three classes, each representing a detail land: .affix, .affix-top, and .affix-bottom. Y'all must provide the styles, with the exception of position: fixed; on .braze, for these classes yourself (contained of this plugin) to handle the actual positions.
Here'south how the affix plugin works:
- To start, the plugin adds
.braze-topto signal the element is in its top-most position. At this betoken no CSS positioning is required. - Scrolling past the element you desire affixed should trigger the actual affixing. This is where
.affixreplaces.affix-topand setsposition: stock-still;(provided by Bootstrap's CSS). - If a bottom offset is defined, scrolling past it should supersede
.brazewith.affix-bottom. Since offsets are optional, setting i requires y'all to prepare the appropriate CSS. In this instance, addposition: absolute;when necessary. The plugin uses the information attribute or JavaScript selection to decide where to position the element from there.
Follow the above steps to set your CSS for either of the usage options below.
Via data attributes
To hands add affix behavior to any element, merely add information-spy="braze" to the chemical element you want to spy on. Use offsets to define when to toggle the pinning of an chemical element.
<div data-spy= "affix" data-offset-top= "threescore" data-showtime-bottom= "200" > ... </div> Via JavaScript
Call the affix plugin via JavaScript:
$ ( '#myAffix' ). affix ({ offset : { summit : 100 , bottom : function () { return ( this . lesser = $ ( '.footer' ). outerHeight ( true )) } } }) Options
Options can be passed via data attributes or JavaScript. For data attributes, suspend the option name to information-, as in information-offset-top="200".
| Name | type | default | description |
|---|---|---|---|
| offset | number | part | object | 10 | Pixels to offset from screen when calculating position of ringlet. If a unmarried number is provided, the outset will exist practical in both top and bottom directions. To provide a unique, lesser and top offset simply provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 }. Use a function when you need to dynamically summate an first. |
| target | selector | node | jQuery element | the window object | Specifies the target element of the affix. |
Methods
.affix(options)
Activates your content as affixed content. Accepts an optional options object.
$ ( '#myAffix' ). affix ({ offset : 15 }) .affix('checkPosition')
Recalculates the state of the braze based on the dimensions, position, and curlicue position of the relevant elements. The .braze, .affix-summit, and .affix-lesser classes are added to or removed from the affixed content according to the new state. This method needs to exist called whenever the dimensions of the affixed content or the target element are changed, to ensure right positioning of the affixed content.
$ ( '#myAffix' ). affix ( 'checkPosition' ) Events
