Comment 1 Simon Pieters 2012-06-20 06:58:55 UTC 
So we have a site compat issue here. Yahoo Mail requires the following to alert true

 a.html: 
 <iframe src=b.html></iframe> 
 <script> 
 function A() { window[0].B(); } 
 onload = A; 
 onmessage = function(e) { alert(e.source === window[0]); }; 
 </script> 

 b.html: 
 <script> 
 function B() { parent.postMessage('foo', '*'); } 
 </script>

That is, .source should be the window of the function that calls postMessage (even if that function was called from another window). The same logic should apply to .origin.

This bug was cloned to create bug 18242 as part of operation convergence.
Comment 3 Ian 'Hixie' Hickson 2012-09-24 03:26:51 UTC 
That's what the "script that invoked the method" is. Why is this ambiguous? The concept of a "script" is defined in quite excruciating detail...
Comment 4 Ian 'Hixie' Hickson 2012-12-02 03:35:07 UTC 
zcorpan: Can you elaborate on what you'd like the spec to say? Would hyperlinking "script" to concept-script be enough?
Comment 5 Simon Pieters 2012-12-03 10:41:20 UTC 
Yeah, I think so.
