This is doing my head in, been chasing it all day. We have an ad server that calls a script on our site which then inserts code.
E.g. Adserver page called in an iframe:
<html>
<head><title></title></head>
<body>
<script src="http://adserver/ad?s=728x90"></script>
</body>
</html>
The javascript returned by the script call above:
document.write('<script type=\'text/javascript\' src=\'http://partner.googleadservices.com/gampad/google_service.js\'>\n');
document.write('</script>\n');
document.write('<script type=\'text/javascript\'>\n');
document.write('GS_googleAddAdSenseService("ca-pub-xxxxxxxxxxxxxxxxxxx");\n');
document.write('GS_googleEnableAllServices();\n');
document.write('</script>\n');
document.write('<script type=\'text/javascript\'>\n');
document.write('GA_googleUseIframeRendering();\n');
document.write('</script>\n');
document.write('\n');
document.write('<script type=\'text/javascript\'>\n');
document.write('GA_googleFillSlotWithSize("ca-pub-xxxxxxxxxxxxxxxxxx", "Global_728x90", 728, 90);\n');
document.write('</script>\n');
This inserts Google Ad Manager ads onto our page. Problem is that the code doesn't work in IE 7 and 8, but works fine in Chrome, Firefox, Safari etc.
The "error" returned by IE is "Object Expected" and running it through IE's "Developer tools" doesn't help either.
I've tried a ton of things to get it working, splitting up the
It seems the error is happening whenever a GS_ or GA_ function is run, so I suspect IE is trying to stop external scripts from writing to the page?
Can anyone shed some light why the error is happening or a solution?
Thanks
I've seen this a lot since posting this question. As far as I understand it, it's a race condition problem that only exists in IE. Unfortunately there is no way around it.
