[Javascript] writing to iframe

[Cutter]

John,

Unfortunately, IE is pretty far from standards compliant. Makes it 
difficult when most users (not us codemonkey types) use IE. You can 
probably find better information on how to deal with this in the W3C 
documentation of the DOM IFrame Object:

http://www.w3schools.com/htmldom/dom_obj_iframe.asp

You will find a specific example of exactly what you are trying to do 
there under the heading "Change the source of frames". I just tried this 
in Firefox and IE and it worked fine, you can view the source of the 
page for better understanding.

I used to almost exclusively code for IE. Since seeing "Mozilla" creep 
higher and higher in my various site logs over the past two years I've 
started to write cross compatible code. I've found (anybody can pipe in 
with a different opinion) that it is easier to write for Firefox, or 
other W3C standards compliant browser, first and then write the 
adjustments/hacks to deal with M$ being behind the eight ball.

My $.02. Hope the link helps,

Cutter
