[ka-Map-users] iframe passing extents back to containing page

[Paul Spencer]

Percy,

I'll try to catch you on IRC (pagameba) but in case I don't ...

If your iframe is loaded from the same site as your main page, then  
you are allowed to script between them.  Whatever triggers your  
query, you can do one of the following:

1) from the main page (in response to clicking a button or  
something), you can call the kaMap object in the frame ...

document.getElementById('frameid').contentWindow.myKaMap.getExtents();

2) from the iframe (in response to an event for instance), you can  
call a function in the parent window ...

window.parent.someFunction();

Cheers

Paul
