检测IE10的兼容模式(Detect IE10 compatibility mode)

我对IE 10的IE版本中的一些特定的代码路径和休息。如果IE10在兼容模式下运行，浏览器版本设置为7.0。有一种方法来检测它是否IE 10不论使用JavaScript / JQuery的标准/兼容模式的？

Answer 1:

您可以检测到这种使用navigator.userAgent字符串，例如

“Mozilla的/ 4.0（兼容; MSIE 7.0; Windows NT的6.2; WOW64; 三叉戟/ 6.0; .NET4.0E; .NET4.0C; InfoPath.3; .NET CLR 3.5.30729; .NET CLR 2.0.50727; .NET CLR 3.0.30729; Zune播放器4.7）”

三叉戟/ 6.0装置IE10

MSIE 7.0装置兼容模式

Answer 2:

这应该检测兼容模式MSIE。

iecheck.js

function trueOrFalse() {
    return true;
}

function IeVersion() {
    //Set defaults
    var value = {
        IsIE: false,
        TrueVersion: 0,
        ActingVersion: 0,
        CompatibilityMode: false
    };

    //Try to find the Trident version number
    var trident = navigator.userAgent.match(/Trident\/(\d+)/);
    if (trident) {
        value.IsIE = true;
        //Convert from the Trident version number to the IE version number
        value.TrueVersion = parseInt(trident[1], 10) + 4;
    }

    //Try to find the MSIE number
    var msie = navigator.userAgent.match(/MSIE (\d+)/);
    if (msie) {
        value.IsIE = true;
        //Find the IE version number from the user agent string
        value.ActingVersion = parseInt(msie[1]);
    } else {
        //Must be IE 11 in "edge" mode
        value.ActingVersion = value.TrueVersion;
    }

    //If we have both a Trident and MSIE version number, see if they're different
    if (value.IsIE && value.TrueVersion > 0 && value.ActingVersion > 0) {
        //In compatibility mode if the trident number doesn't match up with the MSIE number
        value.CompatibilityMode = value.TrueVersion != value.ActingVersion;
    }
    return value;
}

在用户代理字符串三叉戟值指示IE被运行的实际版本。

Answer 4:

这是我从JQuery的使用。就绪

  $(document).ready(function () {
    var iec = new IECompatibility();
    alert('IsIE: ' + iec.IsIE + '\nVersion: ' + iec.Version + '\nCompatability On: ' + iec.IsOn);
  });

  function IECompatibility() {
    var agentStr = navigator.userAgent;
    this.IsIE = false;
    this.IsOn = undefined;  //defined only if IE
    this.Version = undefined;

    if (agentStr.indexOf("MSIE 7.0") > -1) {
      this.IsIE = true;
      this.IsOn = true;
      if (agentStr.indexOf("Trident/6.0") > -1) {
        this.Version = 'IE10';
      } else if (agentStr.indexOf("Trident/5.0") > -1) {
        this.Version = 'IE9';
      } else if (agentStr.indexOf("Trident/4.0") > -1) {
        this.Version = 'IE8';
      } else {
        this.IsOn = false; // compatability mimics 7, thus not on
        this.Version = 'IE7';
      }
    } //IE 7
  }
