accessing javascript objects from another frame

[Halldór Ísak Gylfason]

Hello

basically I have an IFrame inside the top frame. The document in
IFrame defines a javascript object:

var a = new Table();

in the top level frame I want to access this object. I tried doing

document.getEle mentById("IFram eId").document. a

but that didn't work. By the way, I am using IE.

I assume that is a global variable of the IFrame document. That
is, it is a property of its window object.

In IE, you can write
document.getEle mentById("IFram eID").contentWi ndow.a
That won't work in all browsers, though. There is no standard that
includes contentWindow. The DOM HTML specification only describe
documents, so it has a ".contentDocume nt" property, but it won't allow
you to access a global variable of the iframe.

A more portable method is
frames["IFrameID"].a
