Question

我使用以下功能来检测我的IE版本：

function isIE() 
{
    var myNav = navigator.userAgent.toLowerCase();
    return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

如果使用IE浏览器，此代码将返回IE版本，如果使用其他浏览器，则返回false。它可以在IE6，IE9和Chrome中使用。当我尝试Firefox最新版本v20时，它不起作用（网站挂起）。你们知道为什么吗？

或者是否有其他功能可用于检测IE版本？

Answer 1

JQuery有$ .browser：http://api.jquery.com/jQuery.browser/

你可以这样做：

if ($.browser.msie){
}

Answer 2

我用这个

public static class DeviceHelper
{

    public static bool IsMobile(string userAgent)
    {
        userAgent = userAgent.ToLower();
        var currentSubContent = NodeLocator.GetNodeOfExactType<Language>();

        var isMobileDevicesActivatedInBackend = currentSubContent.ActiveForMobileDevices;
        if (isMobileDevicesActivatedInBackend)
        {
            return userAgent.Contains("iphone") |
             userAgent.Contains("ppc") |
             userAgent.Contains("windows ce") |
             userAgent.Contains("blackberry") |
             userAgent.Contains("opera mini") |
                //userAgent.Contains("mobile") |
             userAgent.Contains("palm") |
             userAgent.Contains("portable") |
             (userAgent.Contains("android") && userAgent.Contains("mobile")) |
             (userAgent.Contains("windows") && userAgent.Contains("mobile"));

        }
        else
        {
            return false;
        }
    } 
}

然后你可以从这里添加你需要的东西：检测MSIE的版本

HERE

或在jquery中使用他们的api：

if ($.browser.msie){
}

Answer 3

使用此功能。

function checkVersion() {
        var msg = "You're not using Internet Explorer.";
        var ver = getInternetExplorerVersion();

        if (ver > -1) {
            if (ver >= 8.0)
                msg = "You're using a recent copy of Internet Explorer."
            else
                msg = "You should upgrade your copy of Internet Explorer.";
        }
        alert(msg+" version ->"+ver);
    }

Answer 4

使用IE条件评论，这非常难看但很简单。

编辑：这是基于wikipedia's example

的更好版本

<script>
    var internet_explorer_version = -1;

/*@cc_on

  @if (@_jscript_version == 10)
    internet_explorer_version = 10;

  @elif (@_jscript_version == 9)
    internet_explorer_version = 9;

  @elif (@_jscript_version == 5.8)
    internet_explorer_version = 8;

  @elif (@_jscript_version == 5.7 && window.XMLHttpRequest)
    internet_explorer_version = 7;

  @elif (@_jscript_version == 5.6 || (@_jscript_version == 5.7 && !window.XMLHttpRequest))
    internet_explorer_version = 6;

  @elif (@_jscript_version == 5.5)
    internet_explorer_version = 5.5;

  @end

@*/
</script>

IE4 +仅支持条件注释。较旧的IE或非IE浏览器将跳过所有检查并留下-1。这个脚本检查5.5+，这应该是你需要的任何东西。

Answer 6

你可以使用正则表达式..

<script type="text/javascript">
var userAgent = navigator.userAgent;

var internet_version = -1; 
userAgent.replace(/MSIE .{1,5};/g, function(findS) {
    internet_version = parseFloat(findS.substring(5, findS.length-1));
});

alert(internet_version);
</script>

Answer 7

这对我有用，我已经通过IE11在IE9上测试了它。 IE11中的useragent字符串与之前的版本不同，这就是为什么这里有两个不同的测试。

if (/msie|trident/ig.test(navigator.userAgent)) {
  var matches = navigator.userAgent.match(/MSIE\s([\d\.]+)/) || navigator.userAgent.match(/rv:([\d\.]+)/);
  var ieVersion = parseInt(matches[1], 10);
}

Answer 8

从msdn获得此脚本：

    function getInternetExplorerVersion()
    // Returns the version of Internet Explorer or a -1
    // (indicating the use of another browser).
    // http://msdn.microsoft.com/en-us/library/ms537509(v=vs.85).aspx
    {
      var rv = -1; // Return value assumes failure.
      if (navigator.appName == 'Microsoft Internet Explorer')
      {
        var ua = navigator.userAgent;
        var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
          rv = parseFloat( RegExp.$1 );
      }
      return rv;
    }

就个人而言，我总是只使用条件注释将类应用于<html>。稍后，我在javascript中检查classname。
