Problem

UI experts, I'm trying to get a slow website loaded in an iframe within a jquery modal dialog, but I'm having trouble. This is my use case: - open a jquery dialog, with a single "loading..." gif - load a different URL in the background - once loaded, replace the gif with the URL I'm able to open the URL directly with code as below: ``` var popup = $('<div id="popup123" class="dialog"></div>').prependTo('body'); popup.prepend('<iframe style="display:none" class="dialogIFrame"></iframe>'); $('.dialogIFrame').attr("src", 'http://myslowsite'); $('.dialogIFrame').show(); popup.dialog({ modal: true, title: 'Site', width: 1000, height: 500, }); ``` So my question is - how do I add a "loading..." gif to the mix? Should be possible - but I can't seem to figure out! Thanks in advance!
