[英]Data isn't being passed to Bootstrap modal
I am trying to pass value to a modal using the Bootstrap documentation here .我正在尝试使用此处的 Bootstrap 文档将值传递给模式。 But for some reason the data isn't being passed.但由于某种原因,数据没有被传递。
Button to open modal:打开模态的按钮:
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
Modal模态
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">New message</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="recipient-name" class="col-form-label">Recipient:</label>
<input type="text" class="form-control" id="recipient-name">
</div>
<div class="form-group">
<label for="message-text" class="col-form-label">Message:</label>
<textarea class="form-control" id="message-text"></textarea>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Send message</button>
</div>
</div>
</div>
</div>
Javascript Javascript
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
})
I am using Bootstrap 5+, and for whatever reason It requires data-bs-toggle and data-bs-target in order to open the modal.我正在使用 Bootstrap 5+,无论出于何种原因,它都需要 data-bs-toggle 和 data-bs-target 才能打开模式。
You are using data-whatever instead of data-bs-whatever in the button.您在按钮中使用 data-whatever 而不是 data-bs-whatever。
Change that and everything will work fine.改变它,一切都会正常工作。 See below:见下文:
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 })
