获取Internet Explorer的完整版本号

Question

是否可以获取Internet Explorer的完整版本号，即打开“关于”窗口时看到的版本号？

Answer 1

The IE11 user agent string reports the version of the browser with a revision ("rv") token.

var isIE11 = (navigator.userAgent.indexOf("rv:11.0") != -1);

I personally tested this over jsfiddle with IE11 and this code works
