使用以下代码检查IE浏览器。

console.log(/MSIE|Trident/.test(window.navigator.userAgent))

OR

var isIE = !!document.documentMode; 

console.log(isIE)

谢谢

检测桌面和移动浏览器:Edge, Opera, Chrome, Safari, Firefox, IE

我在@nimesh代码中做了一些更改，现在它也适用于Edge， 和Opera问题修复:

function getBrowserName() {

    if ( navigator.userAgent.indexOf("Edge") > -1 && navigator.appVersion.indexOf('Edge') > -1 ) {
        return 'Edge';
    }
    else if( navigator.userAgent.indexOf("Opera") != -1 || navigator.userAgent.indexOf('OPR') != -1 )
    {
        return 'Opera';
    }
    else if( navigator.userAgent.indexOf("Chrome") != -1 )
    {
        return 'Chrome';
    }
    else if( navigator.userAgent.indexOf("Safari") != -1)
    {
        return 'Safari';
    }
    else if( navigator.userAgent.indexOf("Firefox") != -1 ) 
    {
        return 'Firefox';
    }
    else if( ( navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true ) ) //IF IE > 10
    {
        return 'IE';
    }  
    else 
    {
        return 'unknown';
    }
}

谢谢@nimesh用户:2063564

我们可以使用下面的util方法

utils.isIE = function () {
        var ver = navigator.userAgent;
        return ver.indexOf("MSIE") !== -1 || ver.indexOf("Trident") !== -1; // need to check for Trident for IE11
    };

    utils.isIE32 = function () {
        return (utils.isIE() && navigator.appVersion.indexOf('Win64') === -1);
    };

    utils.isChrome = function () {
        return (window.chrome);
    };

    utils.isFF64 = function () {
        var agent = navigator.userAgent;
        return (agent.indexOf('Win64') >= 0 && agent.indexOf('Firefox') >= 0);
    };

    utils.isFirefox = function () {
        return (navigator.userAgent.toLowerCase().indexOf('firefox') > -1);
    };

谢谢大家。我在最近的浏览器上测试了这里的代码片段:Chrome 55、Firefox 50、IE 11和Edge 38，我想出了下面的组合，对所有这些浏览器都适用。我相信这是可以改进的，但对于任何需要的人来说，这是一个快速的解决方案:

var browser_name = '';
isIE = /*@cc_on!@*/false || !!document.documentMode;
isEdge = !isIE && !!window.StyleMedia;
if(navigator.userAgent.indexOf("Chrome") != -1 && !isEdge)
{
    browser_name = 'chrome';
}
else if(navigator.userAgent.indexOf("Safari") != -1 && !isEdge)
{
    browser_name = 'safari';
}
else if(navigator.userAgent.indexOf("Firefox") != -1 ) 
{
    browser_name = 'firefox';
}
else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
{
    browser_name = 'ie';
}
else if(isEdge)
{
    browser_name = 'edge';
}
else 
{
   browser_name = 'other-browser';
}
$('html').addClass(browser_name);

它将一个CSS类添加到HTML中，带有浏览器的名称。

const isChrome = /Chrome/.test(navigator.userAgent)
const isFirefox = /Firefox/.test(navigator.userAgent)

google浏览器可靠检测的结果通常是检查User代理字符串。这个方法不可靠，因为欺骗这个值很简单。 我已经编写了一个通过duck-typing检测浏览器的方法。

只有在确实有必要时才使用浏览器检测方法，例如显示特定于浏览器的安装扩展指令。尽可能使用特征检测。

演示:https://jsfiddle.net/6spj1059/

// Opera 8.0+ var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0; // Firefox 1.0+ var isFirefox = typeof InstallTrigger !== 'undefined'; // Safari 3.0+ "[object HTMLElementConstructor]" var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && window['safari'].pushNotification)); // Internet Explorer 6-11 var isIE = /*@cc_on!@*/false || !!document.documentMode; // Edge 20+ var isEdge = !isIE && !!window.StyleMedia; // Chrome 1 - 79 var isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime); // Edge (based on chromium) detection var isEdgeChromium = isChrome && (navigator.userAgent.indexOf("Edg") != -1); // Blink engine detection var isBlink = (isChrome || isOpera) && !!window.CSS; var output = 'Detecting browsers by ducktyping:<hr>'; output += 'isFirefox: ' + isFirefox + '<br>'; output += 'isChrome: ' + isChrome + '<br>'; output += 'isSafari: ' + isSafari + '<br>'; output += 'isOpera: ' + isOpera + '<br>'; output += 'isIE: ' + isIE + '<br>'; output += 'isEdge: ' + isEdge + '<br>'; output += 'isEdgeChromium: ' + isEdgeChromium + '<br>'; output += 'isBlink: ' + isBlink + '<br>'; document.body.innerHTML = output;

可靠性分析

前一种方法依赖于呈现引擎的属性(-moz-box-sizing和-webkit-transform)来检测浏览器。这些前缀最终将被删除，所以为了使检测更加健壮，我切换到特定于浏览器的特征:

Internet Explorer: JScript's Conditional compilation (up until IE9) and document.documentMode. Edge: In Trident and Edge browsers, Microsoft's implementation exposes the StyleMedia constructor. Excluding Trident leaves us with Edge. Edge (based on chromium): The user agent include the value "Edg/[version]" at the end (ex: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.16 Safari/537.36 Edg/80.0.361.9"). Firefox: Firefox's API to install add-ons: InstallTrigger Chrome: The global chrome object, containing several properties including a documented chrome.webstore object. Update 3 chrome.webstore is deprecated and undefined in recent versions Safari: A unique naming pattern in its naming of constructors. This is the least durable method of all listed properties and guess what? In Safari 9.1.3 it was fixed. So we are checking against SafariRemoteNotification, which was introduced after version 7.1, to cover all Safaris from 3.0 and upwards. Opera: window.opera has existed for years, but will be dropped when Opera replaces its engine with Blink + V8 (used by Chromium). Update 1: Opera 15 has been released, its UA string looks like Chrome, but with the addition of "OPR". In this version the chrome object is defined (but chrome.webstore isn't). Since Opera tries hard to clone Chrome, I use user agent sniffing for this purpose. Update 2: !!window.opr && opr.addons can be used to detect Opera 20+ (evergreen). Blink: CSS.supports() was introduced in Blink once Google switched on Chrome 28. It's of course, the same Blink used in Opera.

成功测试:

Firefox 0.8 - 61 Chrome 1.0 - 71 Opera 8.0 - 34 Safari 3.0 - 10 Ie 6 - 11 Edge - 20-42 Edge Dev - 80.0.361.9

2016年11月更新，包括检测9.1.3及以上版本的Safari浏览器 2018年8月更新，更新chrome, firefox IE和edge上的最新成功测试。 2019年1月更新，修复了chrome检测(因为window.chrome.webstore已弃用)，并包括最新成功的chrome测试。 2019年12月更新，添加了基于铬检测的Edge(基于@Nimesh评论)。
