Title Body

In Rails 3, passing a :confirm parameter to link_to will populate the data-confirm attribute of the link. This will induce a JS alert() when the link is clicked. I am using the rails jQuery UJS adapter ( https://github.com/rails/jquery-ujs ). The relevant code from rails.js is: $('body').delegate('a[data-confirm], button[data-confirm], input[data-confirm]', 'click.rails', function () { var el = $(this); if (el.triggerAndReturn('confirm')) { if (!confirm(el.attr('data-confirm'))) { return false; } } }); and triggerAndReturn: function (name, data) { var event = new $.Event(name); this.trigger(event, data); return event.result !== false; } I would like to know how this could be modified to instead yield a jQuery dialog (e.g. the jQuery UI Dialog ) allowing the user to confirm or cancel. My knowledge of JavaScript isn't sufficient to achieve this elegantly. My current approach would be to simply rewrite the $('body').delegate() function to instead instantiate a lightbox. However I imagine that there is a more effective approach than this.
