javascript document.getElementById in other frames
You can refer the other frame by using
window.frames["framename"]
and then you can refer the element in the DOM by using
window.frames["framename"].document.getElementById ( "yourelementid" );
I was having problem with the JS version but was able to use these examples for a working jQuery version:
var obj = $('#yourelementid', parent.frames["framename"].document);
The issue may be the current frame you are in. If window.frames['framename']
does not work, try parent.frames['framename']
to access the top level frames.
if(parent.frames && parent.frames['framename']) {
var elem = parent.frames['framename'].document.getElementById(...);
// etc
}
