I’m using Ajax to dynamically populate a DIV. I have each page content stored in XML files as CDATA. When a user clicks on a link from the navigation bar, the Ajax loads the XML for that particular page, parses it, and populates the DIV with it’s content.
Everything is working GREAT, except for one thing. I have a jQuery modal popup whose markup is loaded from that page’s XML file. The .js and .css files from the jQuery plugin are all loaded, and when this is HARD CODED (i.e., not loaded from XML), it works fine. But when it’s loaded from the XML, the modal doesn’t work.
When the page is loaded from the XML file- What the page is supposed to do is load the HTML from the XML file, which it does, and there’s a hyperlink that when clicked, it’s supposed to create the modal popup window. Instead, clicking on the link does NOT fire up the modal popup window.
When the page is hard coded- it does everything it’s supposed to do.
A live example is at:
http://mikemarks.net/clientSites/tabras/
Click on “The Band”, and at the bottom you’ll see the hyperlink called “Demo”. Clicking on that should bring up a modal popup window, but instead as you can see it just takes you to the top of the page.
Below is my markup (notice the div id=”copy”, which is the placeholder for my HTML content that’s loaded from the XML file), my Ajax JavaScript code, and my XML file (which is shown as the markup that’s loaded into the div id=”copy”).

It seems that your webpage lacks of jquery.simplemodal.js and basic.js and the css associated ( for example, for the display:none; on your basic-modal-content )
That’s why you don’t have any modal on load.
Plus, your link or button doesn’t have any event handler (for example, $(‘.basic’).click(…);)
That’s why you don’t have any other action than the anchor.
To remove the anchor action, I recommand to use event.preventDefault
