Brûk Bootstrap's JavaScript modale plugin om dialogen oan jo side ta te foegjen foar ljochtboxen, notifikaasjes fan brûkers, of folslein oanpaste ynhâld.

Hoe't it wurket

Foardat jo begjinne mei de modale komponint fan Bootstrap, wês wis dat jo it folgjende lêze, om't ús menu-opsjes koartlyn binne feroare.

  • Modals binne boud mei HTML, CSS, en JavaScript. Se wurde oer al it oare yn it dokumint pleatst en scroll fuortsmite fan 'e <body>, sadat modale ynhâld ynstee rôlet.
  • Klikje op de modale "eftergrûn" sil de modale automatysk slute.
  • Bootstrap stipet mar ien modaal finster tagelyk. Nested modals wurde net stipe, om't wy leauwe dat se minne brûkersûnderfiningen binne.
  • Modalen brûke position: fixed, wat soms in bytsje spesifyk kin wêze oer syn rendering. As it mooglik is, pleats jo modale HTML op in top-nivo posysje om potinsjele ynterferinsje fan oare eleminten te foarkommen. Jo sille wierskynlik problemen tsjinkomme as jo in .modalbinnen in oar fêst elemint nestelje.
  • Nochris, fanwegen position: fixed, binne d'r wat behertigingen mei it brûken fan modalen op mobile apparaten. Sjoch ús browser-stipedokuminten foar details.
  • Troch hoe't HTML5 syn semantyk definiearret, hat it autofocusHTML-attribút gjin effekt yn Bootstrap-modalen. Om itselde effekt te berikken, brûk wat oanpast JavaScript:
var myModal = document.getElementById('myModal')
var myInput = document.getElementById('myInput')

myModal.addEventListener('shown.bs.modal', function () {
  myInput.focus()
})
It animaasje-effekt fan dizze komponint is ôfhinklik fan 'e prefers-reduced-motionmediafraach. Sjoch de seksje mei fermindere beweging fan ús dokumintaasje foar tagonklikens .

Foarbylden

Hjirûnder is in statysk modaal foarbyld (betsjuttend syn positionen displaybinne oerskreaun). Ynbegrepen binne de modale koptekst, modale lichem (fereaske foar padding), en modale fuottekst (opsjoneel). Wy freegje dat jo, wannear mooglik, modale kopteksten opnimme mei ûntslachaksjes, of in oare eksplisite ûntslachaksje leverje.

Live demo

Skeakelje in wurkjende modale demo troch te klikken op de knop hjirûnder. It sil nei ûnderen glide en ferdwine fan 'e boppekant fan' e side.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Statyske eftergrûn

As eftergrûn is ynsteld op statysk, sil de modale net slute as jo der bûten klikke. Klikje op de knop hjirûnder om it te besykjen.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">
  Launch static backdrop modal
</button>

<!-- Modal -->
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="staticBackdropLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Understood</button>
      </div>
    </div>
  </div>
</div>

Scrolling lange ynhâld

As modalen te lang wurde foar de viewport of apparaat fan de brûker, rôlje se ûnôfhinklik fan 'e side sels. Besykje de demo hjirûnder om te sjen wat wy bedoele.

Jo kinne ek in scrollbere modal meitsje wêrmei it modale lichem kin rôlje troch ta te foegjen .modal-dialog-scrollableoan .modal-dialog.

<!-- Scrollable modal -->
<div class="modal-dialog modal-dialog-scrollable">
  ...
</div>

Fertikaal sintraal

Taheakje .modal-dialog-centeredoan .modal-dialogom de modaal fertikaal te sintrum.

<!-- Vertically centered modal -->
<div class="modal-dialog modal-dialog-centered">
  ...
</div>

<!-- Vertically centered scrollable modal -->
<div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
  ...
</div>

Tooltips en popovers

Tooltips en popovers kinne wurde pleatst binnen modals as nedich. As modalen binne sletten, wurde alle tooltips en popovers binnen ek automatysk wegere.

<div class="modal-body">
  <h5>Popover in a modal</h5>
  <p>This <a href="#" role="button" class="btn btn-secondary popover-test" title="Popover title" data-bs-content="Popover body content is set in this attribute.">button</a> triggers a popover on click.</p>
  <hr>
  <h5>Tooltips in a modal</h5>
  <p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> have tooltips on hover.</p>
</div>

Mei help fan it raster

Brûk it Bootstrap-rastersysteem binnen in modaal troch nêst .container-fluidbinnen de .modal-body. Brûk dan de normale rastersysteemklassen lykas jo earne oars soene.

<div class="modal-body">
  <div class="container-fluid">
    <div class="row">
      <div class="col-md-4">.col-md-4</div>
      <div class="col-md-4 ms-auto">.col-md-4 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-md-3 ms-auto">.col-md-3 .ms-auto</div>
      <div class="col-md-2 ms-auto">.col-md-2 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-md-6 ms-auto">.col-md-6 .ms-auto</div>
    </div>
    <div class="row">
      <div class="col-sm-9">
        Level 1: .col-sm-9
        <div class="row">
          <div class="col-8 col-sm-6">
            Level 2: .col-8 .col-sm-6
          </div>
          <div class="col-4 col-sm-6">
            Level 2: .col-4 .col-sm-6
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

Ferskillende modale ynhâld

Hawwe jo in boskje knoppen dy't allegear deselde modale mei in bytsje ferskillende ynhâld trigger? Brûk event.relatedTargeten HTML- data-bs-*attributen om de ynhâld fan 'e modale te feroarjen ôfhinklik fan hokker knop waard oanklikt.

Hjirûnder is in live demo folge troch foarbyld HTML en JavaScript. Foar mear ynformaasje, lês de modale eveneminten docs foar details oer relatedTarget.

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-bs-whatever="@fat">Open modal for @fat</button>

        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">

          <div class="mb-3">

  </div>
</div>
var exampleModal = document.getElementById('exampleModal')
exampleModal.addEventListener('show.bs.modal', function (event) {
  // Button that triggered the modal
  var button = event.relatedTarget
  // Extract info from data-bs-* attributes
  var recipient = button.getAttribute('data-bs-whatever')
  // If necessary, you could initiate an AJAX request here
  // and then do the updating in a callback.
  //
  // Update the modal's content.
  var modalTitle = exampleModal.querySelector('.modal-title')
  var modalBodyInput = exampleModal.querySelector('.modal-body input')

  modalTitle.textContent = 'New message to ' + recipient
  modalBodyInput.value = recipient
})

Skeakelje tusken modalen

Toggle between multiple modals with some clever placement of the data-bs-target and data-bs-toggle attributes. For example, you could toggle a password reset modal from within an already open sign in modal. Please note multiple modals cannot be open at the same time—this method simply toggles between two separate modals.

Open first modal

Change animation

The $modal-fade-transform variable determines the transform state of .modal-dialog before the modal fade-in animation, the $modal-show-transform variable determines the transform of .modal-dialog at the end of the modal fade-in animation.

If you want for example a zoom-in animation, you can set $modal-fade-transform: scale(.8).

Remove animation

For modals that simply appear rather than fade in to view, remove the .fade class from your modal markup.

<div class="modal" tabindex="-1" aria-labelledby="..." aria-hidden="true">
  ...
</div>

Dynamic heights

If the height of a modal changes while it is open, you should call myModal.handleUpdate() to readjust the modal’s position in case a scrollbar appears.

Accessibility

Be sure to add aria-labelledby="...", referencing the modal title, to .modal. Additionally, you may give a description of your modal dialog with aria-describedby on .modal. Note that you don’t need to add role="dialog" since we already add it via JavaScript.

Embedding YouTube videos

Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. See this helpful Stack Overflow post for more information.

Optional sizes

Modals have three optional sizes, available via modifier classes to be placed on a .modal-dialog. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports.

Size Class Modal max-width
Small .modal-sm 300px
Default None 500px
Large .modal-lg 800px
Extra large .modal-xl 1140px

Our default modal without modifier class constitutes the “medium” size modal.

<div class="modal-dialog modal-xl">...</div>
<div class="modal-dialog modal-lg">...</div>
<div class="modal-dialog modal-sm">...</div>

Fullscreen Modal

Another override is the option to pop up a modal that covers the user viewport, available via modifier classes that are placed on a .modal-dialog.

Class Availability
.modal-fullscreen Always
.modal-fullscreen-sm-down Below 576px
.modal-fullscreen-md-down Below 768px
.modal-fullscreen-lg-down Below 992px
.modal-fullscreen-xl-down Below 1200px
.modal-fullscreen-xxl-down Below 1400px
<!-- Full screen modal -->
<div class="modal-dialog modal-fullscreen-sm-down">

Loop

Responsive fullscreen modals are generated via the $breakpoints map and a loop in scss/_modal.scss.

@each $breakpoint in map-keys($grid-breakpoints) {
  $infix: breakpoint-infix($breakpoint, $grid-breakpoints);
  $postfix: if($infix != "", $infix + "-down", "");

  @include media-breakpoint-down($breakpoint) {
    .modal-fullscreen#{$postfix} {
      width: 100vw;
      max-width: none;
      height: 100%;
      margin: 0;

      .modal-content {
        height: 100%;
        border: 0;
        @include border-radius(0);
      }

      .modal-header {
        @include border-radius(0);
      }

      .modal-body {
        overflow-y: auto;
      }

      .modal-footer {
        @include border-radius(0);
      }
    }
  }
}

Usage

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also overrides default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.

Via data attributes

Activate a modal without writing JavaScript. Set data-bs-toggle="modal" on a controller element, like a button, along with a data-bs-target="#foo" or href="#foo" to target a specific modal to toggle.

<button type="button" data-bs-toggle="modal" data-bs-target="#myModal">Launch modal</button>

Via JavaScript

Create a modal with a single line of JavaScript:

var myModal = new bootstrap.Modal(document.getElementById('myModal'), options)

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-bs-, as in data-bs-backdrop="".

Name Type Default Description
backdrop 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 true Closes the modal when escape key is pressed
focus boolean true Puts the focus on the modal when initialized.

Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our JavaScript documentation for more information.

Passing options

Activates your content as a modal. Accepts an optional options object.

var myModal = new bootstrap.Modal(document.getElementById('myModal'), {
  keyboard: false
})

toggle

Manually toggles a modal. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal or hidden.bs.modal event occurs).

myModal.toggle()

show

Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).

myModal.show()

Also, you can pass a DOM element as an argument that can be received in the modal events (as the relatedTarget property).

var modalToggle = document.getElementById('toggleMyModal') // relatedTarget
myModal.show(modalToggle)

hide

Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs).

myModal.hide()

handleUpdate

Manually readjust the modal’s position if the height of a modal changes while it is open (i.e. in case a scrollbar appears).

myModal.handleUpdate()

dispose

Destroys an element’s modal. (Removes stored data on the DOM element)

myModal.dispose()

getInstance

Static method which allows you to get the modal instance associated with a DOM element

var myModalEl = document.getElementById('myModal')
var modal = bootstrap.Modal.getInstance(myModalEl) // Returns a Bootstrap modal instance

getOrCreateInstance

Static method which allows you to get the modal instance associated with a DOM element, or create a new one in case it wasn’t initialised

var myModalEl = document.querySelector('#myModal')
var modal = bootstrap.Modal.getOrCreateInstance(myModalEl) // Returns a Bootstrap modal instance

Events

Bootstrap’s modal class 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 available as the relatedTarget property of the event.
shown.bs.modal This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event.
hide.bs.modal This event is fired immediately when the hide instance method has been called.
hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
hidePrevented.bs.modal This event is fired when the modal is shown, its backdrop is static and a click outside the modal or an escape key press is performed with the keyboard option or data-bs-keyboard set to false.
var myModalEl = document.getElementById('myModal')
myModalEl.addEventListener('hidden.bs.modal', function (event) {
  // do something...
})
