[mapguide-users] Using Fusion functions from a separate iframe

[Woodman, Jason]

Paul,

Thanks for the explanation on how frames work and how to get a reference
to them. I was trying to reference to functions in my map frame
directly; once I added to 'window.top' to my code I was able to get to
the map frame.

In my JavaScript file I created a reference to the iframe and from there
I was able to use Firefox/Firebug to figure out the objects/functions I
needed to access the map commands.

var map = window.top.frames.map;
var fusion = map.Fusion();
...

Thanks again for you help.
Jason

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.

Cheers

Paul
