Each frame is a separate document, which means it has its own 'window'
global variable. One of the members of window is parent which refers
to the parent window of the current window. Normally this is a self-
reference but if you are using frames then it refers to the parent
frame or frameset. In your case, code running in map iframe can use
window.parent to refer to the parent page. There is another property,
top which refers to the ultimate parent directly in the case of nested
frames. Window also has a frames member which can be used to
reference the individual frames within the window. So ... from the
code iframe, you should be able to do something like this:
window.top.frames.map.someFunction();
which in this case is the same as:
window.parent.frames.map.someFunction();
Note that the same origin policy applies to frames, restricting access
to frames that are loaded from different domains.

I'm trying to access the fusion commands for a map from a javascript
function
in a separate iframe. Does anyone know how to do this and can
supply some
pointers or sample code on how to get a reference to the fusion
commands in
one iframe from another iframe.
Here is my page setup
-------------------------------
| parent page |
| --------------------------- |
| | map iframe | code iframe | |
| --------------------------- |
-------------------------------
My javascript function is in the code iframe, and I need to be able
to have
it access the map functions in the map iframe so I can do things
like select
objects, zoom to a selection, and the like.
Thanks,
