Get someID content
$ ("# Mainiframe "). contents (). find ("someID" ).html () html or $ ("# mainiframe "). contains (). find ("someID "). text () Value

3. In the parent window, select all radio buttons in IFRAME.
$ (Window. frames ["iframe1" cmd.doc ument). find ("input [@ type = 'Radio ']"). attr ("checked", "true ");
