Get browser version of IE using Javascript
提问by Sauron
I am using the following code to get the version of IE in a system.
我正在使用以下代码来获取系统中 IE 的版本。
var browser = navigator.appName;
var b_version = navigator.appVersion;
var version = parseFloat(b_version);
alert(version);
But the version always get is 4 in IE^ and IE7. How can I get the exact version?
但是在IE^和IE7中总是得到的版本是4。我怎样才能得到确切的版本？

It's generally not a good idea to use version detection — in fact, even browser detection isn't recommended! Instead, try object detection.
使用版本检测通常不是一个好主意——事实上，甚至不推荐使用浏览器检测！相反，请尝试对象检测。

You got 4 because of navigator.appVersion strings starts with 4.0 like this.
你得到 4 因为 navigator.appVersion 字符串以 4.0 开头，就像这样。
4.0 (compatible; MSIE 6.0; Windows NT 5.0; ...)
If you do like this, you will get MSIE 6.0for above case
如果你这样做，你会得到MSIE 6.0上述情况
alert(navigator.appVersion.match(/MSIE [\d.]+/))
If you only want 6.0you could do like
如果你只想要6.0你可以像
alert(navigator.appVersion.match(/MSIE ([\d.]+)/)[1])

The below function isIEreturns IE version if IE is detected else returns FALSE
如果检测到 IE，则以下函数isIE返回 IE 版本，否则返回FALSE
function isIE () {
var myNav = navigator.userAgent.toLowerCase();
return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}
This is based on the answer hereby weroro.

Try something like this:
尝试这样的事情：
<script language="javascript">
Event.observe(window, 'load', function() {
var el = $("browserName");
var BO = detectBrowser();
if(BO.ie6){
el.innerHTML = "<b>We do not support IE6. Please click <a href=\"http://www.microsoft.com/windows/downloads/ie/getitnow.mspx\">here</a> to upgrade.</b>";
}else{
el.innerHTML = "<b>Thank You for not running IE6.</b>";
}
});
</script>
