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

这结合了罗伯的原始答案和皮劳2016年的更新

    var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
    // Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
var isFirefox = typeof InstallTrigger !== 'undefined';   // Firefox 1.0+
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
    // At least Safari 3+: "[object HTMLElementConstructor]"
var isChrome = !!window.chrome && !isOpera;              // Chrome 1+
var isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
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 += 'isIE Edge: ' + isEdge + '<br>';
document.body.innerHTML = output;

如果有人觉得这个有用，我已经把Rob W的答案变成了一个返回浏览器字符串的函数，而不是有多个浮动的变量。由于浏览器在不重新加载的情况下也不能真正改变，所以我让它缓存结果，以防止它在下次调用函数时需要计算出来。

/** * Gets the browser name or returns an empty string if unknown. * This function also caches the result to provide for any * future calls this function has. * * @returns {string} */ var browser = function() { // Return cached result if avalible, else get result then cache it. if (browser.prototype._cachedResult) return browser.prototype._cachedResult; // 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'] || safari.pushNotification); // Internet Explorer 6-11 var isIE = /*@cc_on!@*/false || !!document.documentMode; // Edge 20+ var isEdge = !isIE && !!window.StyleMedia; // Chrome 1+ var isChrome = !!window.chrome && !!window.chrome.webstore; // Blink engine detection var isBlink = (isChrome || isOpera) && !!window.CSS; return browser.prototype._cachedResult = isOpera ? 'Opera' : isFirefox ? 'Firefox' : isSafari ? 'Safari' : isChrome ? 'Chrome' : isIE ? 'IE' : isEdge ? 'Edge' : isBlink ? 'Blink' : "Don't know"; }; console.log(browser());

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

var BrowserType; (function (BrowserType) { BrowserType["OPERA"] = "Opera"; BrowserType["OPERA2"] = "OPR"; BrowserType["EDGE"] = "Edg"; BrowserType["CHROME"] = "Chrome"; BrowserType["SAFARI"] = "Safari"; BrowserType["FIREFOX"] = "Firefox"; BrowserType["UNKNOWN"] = "unknown"; })(BrowserType || (BrowserType = {})); const detectBrowser = () => { return Object.values(BrowserType).find((browser) => navigator.userAgent.indexOf(browser) != -1); }; console.log(detectBrowser());

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。
