I think you can.. you can get to the document of the iframe, this way: var iframe = document.getElementById('myframe');// or $('#myframe') [0]; the other is just faster. var doc = iframe.document || iframe.contentDocument || iframe.contentWindow && iframe.contentWindow.document || null; if( !doc ) return; //and now jquery $( selector, doc ).....
If I'm not mistaken, that should do the job, might not work in some browser but it does in most.
