contentDocument for an iframe

Question

What exactly does \"contentDocument\" represent for an iframe (or even the old \"frame\" element)? Is it equivalent to the \"html\" element or the \"body\" element ? What is

Answer 1

contentDocument represents the document of an iframe (DOM object). It is not equivalent to html since documents have their own properties, however if you type:

myFrame.contentDocument.body 

You will get the body itself.

It is supported in all the browsers, with a tiny modification: for Internet Explorer use

myFrame.contentWindow.document
