Reload content in modal (twitter bootstrap)

Question

I'm using twitter bootstrap's modal popup.

<div id="myModal" class="modal hide fade in">
    <div class="modal-header">
        <a class="close" data-dismiss="modal">×</a>
        <h3>Header</h3>
    </div>
    <div class="modal-body"></div>
    <div class="modal-footer">
        <input type="submit" class="btn btn-success" value="Save"/>
    </div>
</div>

I can load content using ajax with this a-element:

<a data-toggle="modal" data-target="#myModal" href="edit.aspx">Open modal</a>

Now I have to open the same modal but using a different url. I'm using this modal to edit an entity from my database. So when I click edit on an entity I need to load the modal with an ID.

<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=1">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=2">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=3">Open modal</a>

If I click on link number 1, it works fine. But if I then click on link number 2 the modal content is already loaded and therefor it will show the content from link number 1.

How can I refresh or reset the ajax loaded content in a twitter bootstrap modal popup?

Answer 1

I guess the way of doing this will be to remove the data-toggle attribute and have a custom handler for the links.

Something in the lines of:

$("a[data-target=#myModal]").click(function(ev) {
    ev.preventDefault();
    var target = $(this).attr("href");
    
    // load the url and show modal on success
    $("#myModal .modal-body").load(target, function() { 
         $("#myModal").modal("show"); 
    });
});

Answer 2

To unload the data when the modal is closed you can use this with Bootstrap 2.x:

$('#myModal').on('hidden', function() {
    $(this).removeData('modal');
});

And in Bootstrap 3 (https://github.com/twbs/bootstrap/pull/7935#issuecomment-18513516):

$(document.body).on('hidden.bs.modal', function () {
    $('#myModal').removeData('bs.modal')
});

//Edit SL: more universal
$(document).on('hidden.bs.modal', function (e) {
    $(e.target).removeData('bs.modal');
});

Answer 3

You can force Modal to refresh the popup by adding this line at the end of the hide method of the Modal plugin (If you are using bootstrap-transition.js v2.1.1, it should be at line 836)

this.$element.removeData()

Or with an event listener

$('#modal').on('hidden', function() {
    $(this).data('modal').$element.removeData();
})

Answer 4

With Bootstrap 3 you can use 'hidden.bs.modal' event handler to delete any modal-related data, forcing the popup to reload next time:

$('#modal').on('hidden.bs.modal', function() {
    $(this).removeData('bs.modal');
});

Answer 5

Based on other answers (thanks everyone).

I needed to adjust the code to work, as simply calling .html wiped the whole content out and the modal would not load with any content after i did it. So i simply looked for the content area of the modal and applied the resetting of the HTML there.

    $(document).on('hidden.bs.modal', function (e) {
        var target = $(e.target);
        target.removeData('bs.modal')
              .find(".modal-content").html('');
    });

Still may go with the accepted answer as i am getting some ugly jump just before the modal loads as the control is with Bootstrap.
