判断IE浏览器版本

IE版本代码总结

IE版本	支持的状态
10及以下	document.all
9及以下	document.all && !window.atob
8及以下	document.all && !document.addEventListener
7及以下	document.all && !document.querySelector
6及以下	document.all && !window.XMLHttpRequest
5.x	document.all && !document.compatMode

 

例子

下面的条件代码只会在IE7及一下浏览器中运行

if (document.all && !document.querySelector) {
alert('IE7 or lower');
}

下面这一个只会运行在IE8中，并且不支持IE7或者IE9：

if (document.all && document.querySelector && !document.addEventListener) {
alert('IE8');
}

下面的条件代码当浏览器为IE11+ 或者非IE时为真

//code from http://caibaojian.com/detect-ie-version.html
if (!document.all) {
alert('IE11+ or not IE');
}

IE11或者非IE

if (!document.all) {
alert('IE11+ or not IE');
}

IE10

if (document.all && document.addEventListener && window.atob) {
alert('IE10');
}

IE9

if (document.all && document.addEventListener && !window.atob) {
alert('IE9');
}

IE8上面已经给出

if (document.all && document.querySelector && !document.addEventListener) {
alert('IE8');
}

IE7

if (document.all && window.XMLHttpRequest && !document.querySelector) {
alert('IE7');
}

IE6

if (document.all && document.compatMode && !window.XMLHttpRequest) {
alert('IE6');
}

检测IE版本

var win = window;
var doc = win.document;
var input = doc.createElement ("input");

var ie = (function (){
//"!win.ActiveXObject" is evaluated to true in IE11
if (win.ActiveXObject === undefined) return null;
if (!win.XMLHttpRequest) return 6;
if (!doc.querySelector) return 7;
if (!doc.addEventListener) return 8;
if (!win.atob) return 9;
//"!doc.body.dataset" is faster but the body is null when the DOM is not
//ready. Anyway, an input tag needs to be created to check if IE is being
//emulated
if (!input.dataset) return 10;
return 11;
})();
