如何检测Safari, Chrome, IE, Firefox和Opera浏览器?

我有5个插件/扩展Firefox, Chrome, Internet Explorer(IE)， Opera和Safari。

我如何正确识别用户浏览器和重定向(一旦安装按钮已被点击)下载相应的插件?

此方法目前对检测所有浏览器有效。我引用vue-element-admin模板

 export function fnBrowserDetect() {
      var browserName = (function(agent) {
        switch (true) {
          case agent.indexOf('edge') > -1: return 'MS Edge'
          case agent.indexOf('edg/') > -1: return 'Edge (chromium based)'
          case agent.indexOf('opr') > -1 && !!window.opr: return 'Opera'
          case agent.indexOf('chrome') > -1 && !!window.chrome: return 'Chrome'
          case agent.indexOf('trident') > -1: return 'MS IE'
          case agent.indexOf('firefox') > -1: return 'Mozilla Firefox'
          case agent.indexOf('safari') > -1: return 'Safari'
          default: return 'other'
        }
      })(window.navigator.userAgent.toLowerCase())
      return browserName.toLowerCase()
    }

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());

您可以尝试以下方法检查浏览器版本。

    <!DOCTYPE html>
    <html>
    <body>
    <p>What is the name(s) of your browser?</p>
    <button onclick="myFunction()">Try it</button>
    <p id="demo"></p>
    <script>
    
    function myFunction() { 
     if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 ) 
    {
        alert('Opera');
    }
    else if(navigator.userAgent.indexOf("Edg") != -1 )
    {
        alert('Edge');
    }
    else if(navigator.userAgent.indexOf("Chrome") != -1 )
    {
        alert('Chrome');
    }
    else if(navigator.userAgent.indexOf("Safari") != -1)
    {
        alert('Safari');
    }
    else if(navigator.userAgent.indexOf("Firefox") != -1 ) 
    {
         alert('Firefox');
    }
    else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
    {
      alert('IE'); 
    }  
    else 
    {
       alert('unknown');
    }
    }
    </script>
    
    </body>
    </html>

如果你只需要知道IE浏览器版本，那么你可以遵循下面的代码。这段代码适用于IE6到IE11版本

<!DOCTYPE html>
<html>
<body>

<p>Click on Try button to check IE Browser version.</p>

<button onclick="getInternetExplorerVersion()">Try it</button>

<p id="demo"></p>

<script>
function getInternetExplorerVersion() {
   var ua = window.navigator.userAgent;
        var msie = ua.indexOf("MSIE ");
        var rv = -1;

        if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer, return version number
        {               

            if (isNaN(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))))) {
                //For IE 11 >
                if (navigator.appName == 'Netscape') {
                    var ua = navigator.userAgent;
                    var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
                    if (re.exec(ua) != null) {
                        rv = parseFloat(RegExp.$1);
                        alert(rv);
                    }
                }
                else {
                    alert('otherbrowser');
                }
            }
            else {
                //For < IE11
                alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
            }
            return false;
        }}
</script>

</body>
</html>

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());

简单:

import getAgent, { getAccurateAgent } from "@egjs/agent";

const agent = getAgent();
getAccurateAgent().then((accurate_agent)=>{
    console.log(agent,'accurate.');
})
console.log(agent);
