Using draggable of parent jquery from within iframe

[daniel.platz]

When accessing the jquery instance defined in a parent from within an iframe, the draggable plugin does not work for an element within an iframe. I.e. var $ = top.$;

$( "#draggable" , document ).draggable({...

does not work because jquery-ui internally uses calls to $(document) and registering mouse event listeners on the parent document but not on the iframe. Using $(this.element[0].ownerDocument) instead for the listeners solved the issue.

the link contains a self-contained example. for it to work locally, in chrome you have to start with --disable-web-security.
