Reload content in modal (twitter bootstrap)

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?

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"); 
    });
});

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');
});

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();
})

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');
});

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.

A little more compressed than the above accepted example. Grabs the target from the data-target of the current clicked anything with data-toggle=modal on. This makes it so you don't have to know what the id of the target modal is, just reuse the same one! less code = win! You could also modify this to load title, labels and buttons for your modal should you want to.

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

Example Links:

<a data-toggle="modal" href="/page/api?package=herp" data-target="#modal">click me</a>
<a data-toggle="modal" href="/page/api?package=derp" data-target="#modal">click me2</a>
<a data-toggle="modal" href="/page/api?package=merp" data-target="#modal">click me3</a>

I made a small change to Softlion answer, so all my modals won't refresh on hide. The modals with data-refresh='true' attribute are only refreshed, others work as usual. Here is the modified version.

$(document).on('hidden.bs.modal', function (e) {
    if ($(e.target).attr('data-refresh') == 'true') {
        // Remove modal data
        $(e.target).removeData('bs.modal');
        // Empty the HTML of modal
        $(e.target).html('');
    }
});

Now use the attribute as shown below,

<div class="modal fade" data-refresh="true" id="#modal" tabindex="-1" role="dialog" aria-labelledby="#modal-label" aria-hidden="true"></div>

This will make sure only the modals with data-refresh='true' are refreshed. And i'm also resetting the modal html because the old values are shown until new ones get loaded, making html empty fixes that one.

Here is a coffeescript version that worked for me.

$(document).on 'hidden.bs.modal', (e) ->
  target = $(e.target)
  target.removeData('bs.modal').find(".modal-content").html('')

I was also stuck on this problem then I saw that the ids of the modal are the same. You need different ids of modals if you want multiple modals. I used dynamic id. Here is my code in haml:

.modal.hide.fade{"id"=> discount.id,"aria-hidden" => "true", "aria-labelledby" => "myModalLabel", :role => "dialog", :tabindex => "-1"}

you can do this

<div id="<%= some.id %>" 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>

and your links to modal will be

<a data-toggle="modal" data-target="#" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>

I hope this will work for you.

It will works for all version of twitterbootstrap

Javascript code :

<script type="text/javascript">
/* <![CDATA[ */
(function(){
   var bsModal = null;
   $("[data-toggle=modal]").click(function(e) {
      e.preventDefault();
      var trgId = $(this).attr('data-target'); 
      if ( bsModal == null ) 
       bsModal = $(trgId).modal;
      $.fn.bsModal = bsModal;
      $(trgId + " .modal-body").load($(this).attr("href"));
      $(trgId).bsModal('show');
    });
 })();
/* <![CDATA[ */
</script>

links to modal are

<a data-toggle="modal" data-target="#myModal" href="edit1.aspx">Open modal 1</a>
<a data-toggle="modal" data-target="#myModal" href="edit2.aspx">Open modal 2</a>
<a data-toggle="modal" data-target="#myModal" href="edit3.aspx">Open modal 3</a>

pop up modal

<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>

You can try this:

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

I wanted the AJAX loaded content removed when the modal closed, so I adjusted the line suggested by others (coffeescript syntax):

$('#my-modal').on 'hidden.bs.modal', (event) ->
  $(this).removeData('bs.modal').children().remove()

var $table = $('#myTable2'); $table.bootstrapTable('destroy');

Worked for me

step 1 : Create a wrapper for the modal called clone-modal-wrapper.

step 2 : Create a blank div called modal-wrapper.

Step 3 : Copy the modal element from clone-modal-wrapper to modal-wrapper.

step 4 : Toggle the modal of modal-wrapper.

<a data-toggle="modal" class='my-modal'>Open modal</a>

<div class="clone-modal-wrapper">
   <div class='my-modal' class="modal fade">
      <div class="modal-dialog">
         <div class="modal-content">
            <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>
      </div>
   </div>
</div>

<div class="modal-wrapper"></div>


$("a[data-target=#myModal]").click(function (e) {
	e.preventDefault();
	$(".modal-wrapper").html($(".clone-modal-wrapper").html());
    $('.modal-wrapper').find('.my-modal').modal('toggle');
});
