Attach an event in a child iframe to a handler in the parent window

Use contents() to access the Document object inside an iframe. Note that there are in general problems with using a jQuery library in one document to manipulate another document and it should in general be avoided. However, in the case of binding events it does work.

$('[name=temp_iframe]').contents().find('button').click(function() {
    alert('click');
});

This requires that the iframe and its contents are loaded, so do it in a $(window).load() handler if necessary. You can’t live/delegate across documents, as events don’t propagate from a child document into its parent.
