JavaScript Confirmation Modal using Bootstrap

If you dont know what is it bootstrap you must read about it in this link : http://getbootstrap.com/

others ways this article would not help you.

Say we have this links (note data-href instead of href) or buttons that we want to have delete confirmation for:

<a href="#" data-href="delete.php?id=23" data-toggle="modal" data-target="#confirm-delete">Delete record #23</a>

<button class="btn btn-default" data-href="/delete.php?id=54" data-toggle="modal" data-target="#confirm-delete">
    Delete record #54
</button>

Here #confirm-delete points to a modal popup div in your HTML. It should have an "OK" button configured like this:

<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                ...
            </div>
            <div class="modal-body">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a class="btn btn-danger btn-ok">Delete</a>
            </div>
        </div>
    </div>
</div>

Now you only need this little javascript to make a delete action confirmable:

$('#confirm-delete').on('show.bs.modal', function(e) {
    $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});

So on show.bs.modal event delete button href is set to URL with corresponding record id.
