One more question about manipulating iframes. In a script I’ve looked through to investigate AJAX file uploads, there is this technique for accessing the contents of an iframe:
[CODE] if(frame.contentWindow)
{
var thebody = frame.contentWindow.document.body;
}else if(frame.contentDocument)
{
var thebody = frame.contentDocument.document.body;
}
I haven’t been able to find much info on contentWindow and contentDocument. In fact, other sources I’ve found talk only about using contentWindow to access an iframe’s contents, ignoring contentDocument completely. What is the difference between the two, and what browsers is the contentDocument check targeting? Any modern browsers, or is this a backward compatibility thing?
