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?

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。

短变体(更新2020年7月10日移动浏览器检测修复)

打字文件版本:

export enum BROWSER_ENUM {
  EDGE ,
  INTERNET_EXPLORER ,
  FIRE_FOX ,
  OPERA ,
  UC_BROWSER ,
  SAMSUNG_BROWSER ,
  CHROME ,
  SAFARI ,
  UNKNOWN ,
}

const testUserAgent = (regexp: RegExp): boolean => regexp.test(window.navigator.userAgent);

function detectBrowser(): BROWSER_ENUM {
  switch (true) {
    case testUserAgent(/edg/i): return BROWSER_ENUM.EDGE;
    case testUserAgent(/trident/i): return BROWSER_ENUM.INTERNET_EXPLORER;
    case testUserAgent(/firefox|fxios/i): return BROWSER_ENUM.FIRE_FOX;
    case testUserAgent(/opr\//i): return BROWSER_ENUM.OPERA;
    case testUserAgent(/ucbrowser/i): return BROWSER_ENUM.UC_BROWSER;
    case testUserAgent(/samsungbrowser/i): return BROWSER_ENUM.SAMSUNG_BROWSER;
    case testUserAgent(/chrome|chromium|crios/i): return BROWSER_ENUM.CHROME;
    case testUserAgent(/safari/i): return BROWSER_ENUM.SAFARI;
    default: return BROWSER_ENUM.UNKNOWN;
  }
}

export const BROWSER: BROWSER_ENUM = detectBrowser();

export const IS_FIREFOX = BROWSER === BROWSER_ENUM.FIRE_FOX;

函数式算法，只是为了好玩:

 const BROWSER =  Object.entries({
     "Microsoft Edge": /edg/i,
     "Microsoft Internet Explorer": /trident/i,
     "Mozilla Firefox": /firefox|fxios/i,
     "Opera": /opr\//i,
     "UC Browser": /ucbrowser/i,
     "Samsung Browser": /samsungbrowser/i,
     "Google Chrome": /chrome|chromium|crios/i,
     "Apple Safari": /safari/i,
     "Unknown": /.+/i,
 }).find(([, value]) => value.test(window.navigator.userAgent)).pop();

如果您需要知道某个特定浏览器的数字版本是什么，可以使用下面的代码片段。目前它会告诉你Chrome/Chromium/Firefox的版本:

var match = $window.navigator.userAgent.match(/(?:Chrom(?:e|ium)|Firefox)\/([0-9]+)\./);
var ver = match ? parseInt(match[1], 10) : 0;

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>

});

简单的一行JavaScript代码会告诉你浏览器的名称:

function GetBrowser()
{
    return  navigator ? navigator.userAgent.toLowerCase() : "other";
}
