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()
    }

UAParser是一个JavaScript库，用于从userAgent字符串中识别浏览器、引擎、操作系统、CPU和设备类型/型号。

有一个CDN可用。在这里，我包含了一个使用UAParser检测浏览器的示例代码。

<!doctype html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/ua-parser-js@0/dist/ua-parser.min.js"></script>
<script type="text/javascript">
    var parser = new UAParser();
    var result = parser.getResult();
    console.log(result.browser);     // {name: "Chromium", version: "15.0.874.106"}
</script>
</head>
<body>
</body>
</html>

现在您可以使用result的值。浏览器有条件地编程您的页面。

你可以使用Detect-browser.js，这个JavaScript库可以检测并打印一个浏览器信息对象，包括浏览器语言/名称、用户代理、设备类型、用户操作系统、引用器、在线/离线、用户时区、屏幕分辨率和启用cookie。

从这里获取detect-browser.js

它会给你这样的东西:

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

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

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());

var BrowserDetect = {
        init: function () {
            this.browser = this.searchString(this.dataBrowser) || "Other";
            this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) || "Unknown";
        },
        searchString: function (data) {
            for (var i = 0; i < data.length; i++) {
                var dataString = data[i].string;
                this.versionSearchString = data[i].subString;

                if (dataString.indexOf(data[i].subString) !== -1) {
                    return data[i].identity;
                }
            }
        },
        searchVersion: function (dataString) {
            var index = dataString.indexOf(this.versionSearchString);
            if (index === -1) {
                return;
            }

            var rv = dataString.indexOf("rv:");
            if (this.versionSearchString === "Trident" && rv !== -1) {
                return parseFloat(dataString.substring(rv + 3));
            } else {
                return parseFloat(dataString.substring(index + this.versionSearchString.length + 1));
            }
        },

        dataBrowser: [
            {string: navigator.userAgent, subString: "Edge", identity: "MS Edge"},
            {string: navigator.userAgent, subString: "MSIE", identity: "Explorer"},
            {string: navigator.userAgent, subString: "Trident", identity: "Explorer"},
            {string: navigator.userAgent, subString: "Firefox", identity: "Firefox"},
            {string: navigator.userAgent, subString: "Opera", identity: "Opera"},  
            {string: navigator.userAgent, subString: "OPR", identity: "Opera"},  

            {string: navigator.userAgent, subString: "Chrome", identity: "Chrome"}, 
            {string: navigator.userAgent, subString: "Safari", identity: "Safari"}       
        ]
    };

    BrowserDetect.init();


    var bv= BrowserDetect.browser;
    if( bv == "Chrome"){
        $("body").addClass("chrome");
    }
    else if(bv == "MS Edge"){
     $("body").addClass("edge");
    }
    else if(bv == "Explorer"){
     $("body").addClass("ie");
    }
    else if(bv == "Firefox"){
     $("body").addClass("Firefox");
    }


$(".relative").click(function(){
$(".oc").toggle('slide', { direction: 'left', mode: 'show' }, 500);
$(".oc1").css({
   'width' : '100%',
   'margin-left' : '0px',
   });
});
