Twitter bootstrap remote modal shows same content every time

Question

The problem is two-fold.

First, once a Modal object is instantiated, it is persistently attached to the element specified by data-target and subsequent calls to show that modal will only call toggle() on it, but will not update the values in the options. So, even though the href attributes are different on your different links, when the modal is toggled, the value for remote is not getting updated. For most options, one can get around this by directly editing the object. For instance:

$('#myModal').data('bs.modal').options.remote = "http://website.com/item/7";

However, that won't work in this case, because...

Second, the Modal plugin is designed to load the remote resource in the constructor of the Modal object, which unfortunately means that even if a change is made to the options.remote, it will never be reloaded.

A simple remedy is to destroy the Modal object before subsequent toggles. One option is to just destroy it after it finishes hiding:

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

_{Note: Adjust the selectors as needed. This is the most general.}

Plunker

Or you could try coming up with a more complicated scheme to do something like check whether the link launching the modal is different from the previous one. If it is, destroy; if it isn't, then no need to reload.

For bootstrap 3 you should use:

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

For Bootstrap 3.1 you'll want to remove data and empty the modal-content rather than the whole dialog (3.0) to avoid the flicker while waiting for remote content to load.

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

If you are using non-remote modals then the above code will, of course, remove their content once closed (bad). You may need to add something to those modals (like a .local-modal class) so they aren't affected. Then modify the above code to:

$(document).on("hidden.bs.modal", ".modal:not(.local-modal)", function (e) {
    $(e.target).removeData("bs.modal").find(".modal-content").empty();
});

Thanks merv. I started tinkering around boostrap.js but your answer is a quick and clean workaround. Here's what I ended up using in my code.

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

The accepted answer didn't work for me, so I went with JavaScript to do it.

<a href="/foo" class="modal-link">
<a href="/bar" class="modal-link">

<script>
$(function() {
    $(".modal-link").click(function(event) {
        event.preventDefault()
        $('#myModal').removeData("modal")
        $('#myModal').modal({remote: $(this).attr("href")})
    })
})

This works with Bootstrap 3 FYI

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