问题
Our application runs fine in IE7 and IE8. We use the X-UA-Compatible header to force the browser to use IE7 standards document mode. This is about which rendering engine will be used afai get the picture.
In IE9 however there are a bunch of things which stopped working. In IE9 the document mode is IE7 standards, but the browser mode remains IE9.
When I manually change the browser mode (using the developer tools) to IE7, all is fine again.
Is there a way to programmatically force BROWSER MODE?
回答1:
It seems this is not possible.
