I have this simple line
alert(window.parent.frames[0].document.getElementById(\'textToSearch\').value);
I have 2 frames, first with a text
Finally i figure what was the problem. I try the code from above on Google Chrome on a system local file. Due the security settings of Google Chrome this usecase is impossible. If i move all files on a web server this will work as a charm Thanks all for your support, this thread can be closed now
Use contentWindow.document
instead of document
:
var frame = window.parent.frames[0].contentWindow;
alert(frame.document.getElementById('textToSearch').value);
You can also just use contentDocument
for most browsers, but not Internet Explorer 7 or older.
