How can I get an element from within a frameset frame using JavaScript?

Question

I need to access and element from within a frameset frame. For example if I have the following markup:

<frameset rows="33%,33%,*">   <frame src="frame1.html"/>   <frame src="frame2.html"/>   <frame src="frame3.html"/> </frameset> 

How can I get some element from one of the child frames? I have tried this:

window.frames[1].getElementById('someElementId') 

This results in a type error :

getElementById() is not a function.

Can someone assist?

Thanks!

You need to get the Document object for the frame.

window.frames[1].document.getElementById('someElementId')
