i have found solution problem:

the thought set onload event before set src.

you can seek code:

document.getelementsbytagname('iframe').onload=function(){ try{ var win=this.contentwindow; win.closed && error_function(); }catch(e){ error_function(); } };

check here how works: http://jsfiddle.net/tec6y2y9/1/

note: on fiddle, made changes show works! error_function() fictional function show set code in case of failure!

i hope works you.
