回答1:
this works for me..
<!DOCTYPE html>
<html>
<head>
<title>title</title>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
回答2:
Do you have any other links or scripts above your X-UA-Compatible meta tag in your <head>? If so this might be causing the problem.
Also make sure to check the compatibility settings in your browser itself by going to:
Tools --> Compatability View Settings
回答3:
There are several possible explanations, such as HTTP headers overriding the meta tag, domain name being blacklisted by Microsoft, or your local admin having forced IE to Compatibility mode. For a description of some possibilities and possible cures, check out IE8 and IE9 Complications in “Activating Browser Modes with Doctype”.
