Problems accessing DOM with Firefox, IE

can't change innerHTML for parent's parent's <title>

[phillipandrews]

I have a frameset within a frameset, for reasons I will not take the time to explain. I am trying to use JavaScript to change the title of the page that holds the main frameset, so the text in the title bar of the browser will change.
But when I try to do anything with parent.parent.document.getElementById("maintitle").innerHTML, Firefox (v1.0PR) whines, saying parent.parent.document.getElementById("maintitle") has no properties. In Internet Explorer (v6.0), I can access the innerHTML, but can't seem to change it because of an "Unknown Runtime Error." Is this a security issue or something else?

-Thanks,
Phillip

Hi.

This is not a security issue, but I think you might need an extra reference between parent.parent. and document to reference the frame that contains the element 'maintitle'. Something like:

parent.parent.FRAMENAME.document.getElementById("maintitle")

Kind regards,

Andrew
