我有一些适用于 IE 10 和其他 IE 版本的特定代码路径。如果 IE10 在兼容模式下运行，则浏览器版本设置为 7.0。无论使用 JavaScript/JQuery 的标准/兼容模式如何，有没有办法检测它是否是 IE 10？

您可以使用navigator.userAgent字符串检测到这一点，例如

“Mozilla/4.0（兼容；MSIE 7.0；Windows NT 6.2；WOW64； Trident/6.0；.NET4.0E；.NET4.0C；InfoPath.3；.NET CLR 3.5.30729；.NET CLR 2.0.50727；.NET CLR 3.0.30729；Zune 4.7)"

Trident/6.0 表示 IE10

MSIE 7.0 表示兼容模式

这应该可以检测 MSIE 的兼容模式。

即检查.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;
}

即检查.html

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title>Testing IE Compatibility Mode</title>
    <script src="iecheck.js" type="text/javascript"></script>
</head>
<body>
<div id="results">Results: </div>
</br>
<script type="text/javascript">

var ie = IeVersion();

document.write("IsIE: " + ie.IsIE + "</br>");
document.write("TrueVersion: " + ie.TrueVersion + "</br>");
document.write("ActingVersion: " + ie.ActingVersion + "</br>");
document.write("CompatibilityMode: " + ie.CompatibilityMode + "</br>");

</script>
</body>
</html>

用户代理字符串中的 Trident 值表示正在运行的 IE 的实际版本。

这是我从 JQuery .ready 中使用的

  $(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
  }
