Thread:Project:Support desk/jquery draggable divs

MediaWiki 1.17.0; PHP 5.2.10 (apache); MySQL 5.1.41-log.

Can't make jquery draggable divs work. I added to Common.js this:

jQuery(".c1").ready(   function     {       jQuery(this).find('.c1').draggable;    });

Then I write on some page this:

lorem ipsum

But this div isn't draggable. What's wrong?
