Howeve开发者_如何学JAVAr, if i view it with IE9, it throws it into IE9 Compat View / Document mode: IE7 Standards

Any ideas why?

Often that can happen when there is a problem with your doctype .. like if it were missing. That's the first place I'd look. It would be difficult to troubleshoot further without code to sift through.
