我知道我回答这个问题已经太晚了,但我想我应该把我的片段放在这里。这里的很多答案都很好,而且,正如有人指出的那样,通常最好使用功能检测,而不是依赖userAgent字符串。然而,如果您打算走这条路,我已经编写了一个完整的代码片段,以及一个替代的 jQuery 实现来替换已废弃的 $.browser


Vanilla JS

我的第一个代码片段只是向 navigator 对象添加了四个属性:browserversionmobile 和 & 。 webkit

jsFiddle


/** navigator [extended]
 *  Simply extends Browsers navigator Object to include browser name, version number, and mobile type (if available).
 *
 *  @property {String} browser The name of the browser.
 *  @property {Double} version The current Browser version number.
 *  @property {String|Boolean} mobile Will be `false` if is not found to be mobile device. Else, will be best guess Name of Mobile Device (not to be confused with browser name)
 *  @property {Boolean} webkit If is webkit or not.

I know I'm WAY late to this question, but figured I'd throw my snippets up here. A lot of the answers here are OK, and, as one points out, it's generally best to use feature detection rather than rely on the userAgent string. However, if you are going to go that route, I've written a complete snippet, as well as an alternate jQuery implementation to replace the depricated $.browser.


Vanilla JS

My first snippet simply adds four properties to the navigator object: browser, version, mobile, & webkit.

jsFiddle


/** navigator [extended]
 *  Simply extends Browsers navigator Object to include browser name, version number, and mobile type (if available).
 *
 *  @property {String} browser The name of the browser.
 *  @property {Double} version The current Browser version number.
 *  @property {String|Boolean} mobile Will be `false` if is not found to be mobile device. Else, will be best guess Name of Mobile Device (not to be confused with browser name)
 *  @property {Boolean} webkit If is webkit or not.

不完全是您想要的,但接近它:

var jscriptVersion = /*@cc_on @if(@_jscript) @_jscript_version @else @*/ false /*@end @*/;
var geckoVersion = navigator.product === 'Gecko' && navigator.productSub;
var operaVersion = 'opera' in window && 'version' in opera && opera.version();

变量将包含适当的版本,如果不可用,则为 false

如果使用 Chrome 的人能够了解您是否可以以与 window.opera 类似的方式使用 window.chrome,我将不胜感激。

Not exactly what you want, but close to it:

var jscriptVersion = /*@cc_on @if(@_jscript) @_jscript_version @else @*/ false /*@end @*/;
var geckoVersion = navigator.product === 'Gecko' && navigator.productSub;
var operaVersion = 'opera' in window && 'version' in opera && opera.version();

The variables will contain the appropriate version or false if it is not available.

I'd appreciate it if someone using Chrome could find out if you can use window.chrome in a similar way to window.opera.

有时我们需要简单的方法来检查浏览器是否是IE。它可能是这样的:

 var isMSIE = (/trident/i).test(navigator.userAgent);

 if(isMSIE)
 {
  /* do something for ie */
 }
 else
 {
  /* do something else */
 }

或简化的 siva 方法:

 if(!!navigator.systemLanguage)
 {
  /* do something for ie */
 }
 else
 {
  /* do something else */
 }

MSIE v.11 检查:

if( (/trident/i).test(navigator.userAgent) && (/rv:/i).test(navigator.userAgent) )
{
  /* do something for ie 11 */
}

其他 IE 浏览器在其 userAgent 属性中包含 MSIE 字符串,并且可以被它捕获。

Some times we need simple method to check if the browser is IE or not. This is how it could be:

 var isMSIE = (/trident/i).test(navigator.userAgent);

 if(isMSIE)
 {
  /* do something for ie */
 }
 else
 {
  /* do something else */
 }

or simplified siva's method:

 if(!!navigator.systemLanguage)
 {
  /* do something for ie */
 }
 else
 {
  /* do something else */
 }

MSIE v.11 check:

if( (/trident/i).test(navigator.userAgent) && (/rv:/i).test(navigator.userAgent) )
{
  /* do something for ie 11 */
}

other IE browsers contain MSIE string in their userAgent property and could be catched by it.

我发现了一些有趣且更快的方法。
IE 支持 navigator.systemLanguage,它返回“en-US”,而其他浏览器返回 undefined

<script>
    var lang = navigator.systemLanguage;
    if (lang!='en-US'){document.write("Well, this is not internet explorer");}
    else{document.write("This is internet explorer");}
</script>

I found something interesting and quicker way.
IE supports navigator.systemLanguage which returns "en-US" where other browsers return undefined.

<script>
    var lang = navigator.systemLanguage;
    if (lang!='en-US'){document.write("Well, this is not internet explorer");}
    else{document.write("This is internet explorer");}
</script>

我做了这个小功能,希望对你有帮助。在这里您可以找到最新版本
浏览器检测

function detectBrowser(userAgent){
  var chrome  = /.*(Chrome\/).*(Safari\/).*/g;
  var firefox = /.*(Firefox\/).*/g;
  var safari  = /.*(Version\/).*(Safari\/).*/g;
  var opera   = /.*(Chrome\/).*(Safari\/).*(OPR\/).*/g

  if(opera.exec(userAgent))
    return "Opera"
  if(chrome.exec(userAgent))
    return "Chrome"
  if(safari.exec(userAgent))
    return "Safari"
  if(firefox.exec(userAgent))
    return "Firefox"
}

I make this small function, hope it helps. Here you can find the latest version
browserDetection

function detectBrowser(userAgent){
  var chrome  = /.*(Chrome\/).*(Safari\/).*/g;
  var firefox = /.*(Firefox\/).*/g;
  var safari  = /.*(Version\/).*(Safari\/).*/g;
  var opera   = /.*(Chrome\/).*(Safari\/).*(OPR\/).*/g

下面的代码片段将展示如何根据 IE 版本和浏览器显示 UI 元素

$(document).ready(function () {

var msiVersion = GetMSIieversion();
if ((msiVersion <= 8) && (msiVersion != false)) {

    //Show UI elements specific to IE version 8 or low

    } else {
    //Show UI elements specific to IE version greater than 8 and for other browser other than IE,,ie..Chrome,Mozila..etc
    }
}
);

下面的代码将给出如何获取 IE 版本

function GetMSIieversion() {

var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
    // IE 10 or older => return version number
    return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}

var trident = ua.indexOf('Trident/');
if (trident > 0) {
    // IE 11 => return version number
    var rv = ua.indexOf('rv:');
    return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}

var edge = ua.indexOf('Edge/');
if (edge > 0) {
    // Edge (IE 12+) => return version number
    return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}

// other browser like Chrome,Mozila..etc
return false;

}

Below code snippet will show how how you can show UI elemnts depends on IE version and browser

$(document).ready(function () {

var msiVersion = GetMSIieversion();
if ((msiVersion <= 8) && (msiVersion != false)) {

    //Show UI elements specific to IE version 8 or low

    } else {
    //Show UI elements specific to IE version greater than 8 and for other browser other than IE,,ie..Chrome,Mozila..etc
    }
}
);

Below code will give how we can get IE version

function GetMSIieversion() {

var ua = window.navigator.userAgent;
var msie = ua.indexOf('MSIE ');
if (msie > 0) {
    // IE 10 or older => return version number
    return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
}

var trident = ua.indexOf('Trident/');
if (trident > 0) {
    // IE 11 => return version number
    var rv = ua.indexOf('rv:');
    return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
}

var edge = ua.indexOf('Edge/');
if (edge > 0) {
    // Edge (IE 12+) => return version number
    return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
}

// other browser like Chrome,Mozila..etc
return false;

}

  if (temp !== null) {
    match.splice(1, 1, temp[1])
  }

  return match.join(' ')
})()

console.log(navigator.saysWho) // outputs: `Chrome 89`

顾名思义,这将告诉您浏览器提供的名称和版本号。

当您在多个浏览器上测试新代码时,它可以方便地对测试和错误结果进行排序。

navigator.saysWho = (() => {
  const { userAgent } = navigator
  let match = userAgent.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || []
  let temp

  if (/trident/i.test(match[1])) {
    temp = /\brv[ :]+(\d+)/g.exec(userAgent) || []

    return `IE ${temp[1] || ''}`
  }

  if (match[1] === 'Chrome') {
    temp = userAgent.match(/\b(OPR|Edge)\/(\d+)/)

    if (temp !== null) {
      return temp.slice(1).join(' ').replace('OPR', 'Opera')
    }

    temp = userAgent.match(/\b(Edg)\/(\d+)/)

    if (temp !== null) {
      return temp.slice(1).join(' ').replace('Edg', 'Edge (Chromium)')
    }
  }

  match = match[2] ? [ match[1], match[2] ] : [ navigator.appName, navigator.appVersion, '-?' ]
  temp = userAgent.match(/version\/(\d+)/i)

  if (temp !== null) {
    match.splice(1, 1, temp[1])
  }

  return match.join(' ')
})()

console.log(navigator.saysWho) // outputs: `Chrome 89`

As the name implies, this will tell you the name and version number supplied by the browser.

It is handy for sorting test and error results, when you are testing new code on multiple browsers.

我建议使用小型 javascript 库 Bowser。它基于 navigator.userAgent 并针对所有浏览器(包括 iPhone、Android 等)进行了良好的测试。

https://github.com/ded/bowser

你可以简单地说:

if (bowser.msie && bowser.version <= 6) {
  alert('Hello IE');
} else if (bowser.firefox){
  alert('Hello Foxy');
} else if (bowser.chrome){
  alert('Hello Chrome');
} else if (bowser.safari){
  alert('Hello Safari');
} else if(bowser.iphone || bowser.android){
  alert('Hello mobile');
}

I recommend using the tiny javascript library Bowser. It is based on the navigator.userAgent and quite well tested for all browsers including iphone, android etc.

https://github.com/ded/bowser

You can use simply say:

if (bowser.msie && bowser.version <= 6) {
  alert('Hello IE');
} else if (bowser.firefox){
  alert('Hello Foxy');
} else if (bowser.chrome){
  alert('Hello Chrome');
} else if (bowser.safari){
  alert('Hello Safari');
} else if(bowser.iphone || bowser.android){
  alert('Hello mobile');
}

以下是 2016 年检测浏览器的方法,包括 Microsoft Edge、Safari 10 和 Blink 检测:

// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Firefox 1.0+
isFirefox = typeof InstallTrigger !== 'undefined';
// Safari 3.0+
isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);
// Internet Explorer 6-11
isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
isChrome = !!window.chrome && !!window.chrome.webstore;
// Blink engine detection
isBlink = (isChrome || isOpera) && !!window.CSS;

这种方法的优点在于它依赖于浏览器引擎属性,因此它甚至涵盖了几乎兼容的衍生浏览器,例如 Yandex 或 Vivaldi与他们使用其引擎的主要浏览器。 Opera 是个例外,它依赖于用户代理嗅探,但如今(即版本 15 及更高版本)甚至 Opera 本身也只是 Blink 的一个外壳。

Here's how to detect browsers in 2016, including Microsoft Edge, Safari 10 and detection of Blink:

// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Firefox 1.0+
isFirefox = typeof InstallTrigger !== 'undefined';
// Safari 3.0+
isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);
// Internet Explorer 6-11
isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
isChrome = !!window.chrome && !!window.chrome.webstore;
// Blink engine detection
isBlink = (isChrome || isOpera) && !!window.CSS;

The beauty of this approach is that it relies on browser engine properties, so it covers even derivative browsers, such as Yandex or Vivaldi, which are practically compatible with the major browsers whose engines they use. The exception is Opera, which relies on user agent sniffing, but today (i.e. ver. 15 and up) even Opera is itself only a shell for Blink.

通常最好尽可能避免特定于浏览器的代码。 JQuery $.support 属性可用于检测对特定功能的支持,而不是依赖于浏览器名称和版本。

例如,在 Opera 中,您可以伪造 Internet Explorer 或 Firefox 实例。

alt text

详细说明JQuery.support 可以在这里找到: http://api.jquery.com/jQuery.support/< /a>

现在根据 jQuery 已弃用。

我们强烈建议使用外部库,例如 Modernizr
而不是依赖于 jQuery.support 中的属性。

在编写网站代码时,我始终确保非 js 用户也可以访问导航等基本功能。如果主页针对特殊受众,这可能会引起讨论,并且可以忽略。

It is usually best to avoid browser-specific code where possible. The JQuery $.support property is available for detection of support for particular features rather than relying on browser name and version.

In Opera for example, you can fake an internet explorer or firefox instance.

alt text

A detailed description of JQuery.support can be found here: http://api.jquery.com/jQuery.support/

Now deprecated according to jQuery.

We strongly recommend the use of an external library such as Modernizr
instead of dependency on properties in jQuery.support.

When coding websites, I always make sure, that basic functionality like navigation is also accessible to non-js users. This may be object to discussion and can be ignored if the homepage is targeted to a special audience.

由于 Internet Explorer 11 (IE11+) 出现并且不再使用 MSIE 标签名称,我提出了旧检测函数的变体:

navigator.sayswho= (function(){
    var N= navigator.appName, ua= navigator.userAgent, tem;

    // if IE11+
    if (new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})").exec(ua) !== null) {
        var M= ["Internet Explorer"];
        if(M && (tem= ua.match(/rv:([0-9]{1,}[\.0-9]{0,})/))!= null) M[2]= tem[1];
        M= M? [M[0], M[2]]: [N, navigator.appVersion,'-?'];
        return M;
    }

    var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
    if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
    M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
    return M;
})();

Since Internet Explorer 11 (IE11+) came out and is not using the tag name of MSIE anymore I came up with a variance of an older detection function:

navigator.sayswho= (function(){
    var N= navigator.appName, ua= navigator.userAgent, tem;

    // if IE11+
    if (new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})").exec(ua) !== null) {
        var M= ["Internet Explorer"];
        if(M && (tem= ua.match(/rv:([0-9]{1,}[\.0-9]{0,})/))!= null) M[2]= tem[1];
        M= M? [M[0], M[2]]: [N, navigator.appVersion,'-?'];
        return M;
    }

    var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
    if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
    M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
    return M;
})();

遗憾的是,IE11 的 navigator.userAgent 中不再有 MSIE

Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; OfficeLiveConnector.1.5; OfficeLivePatch.1.3; .NET4.0C; BRI/2; BOIE9;ENUS; rv:11.0) like Gecko

至于为什么你想知道你正在使用哪个浏览器,那是因为每个浏览器都有自己的一套错误,您最终会实施特定于浏览器和版本的解决方法,或者告诉用户使用不同的浏览器!

Sadly, IE11 no longer has MSIE in its navigator.userAgent:

Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; OfficeLiveConnector.1.5; OfficeLivePatch.1.3; .NET4.0C; BRI/2; BOIE9;ENUS; rv:11.0) like Gecko

As to why you want to know which browser you're using, it's because every browser has its own set of bugs, and you end up implementing browser and version specific workarounds, or tell the user to use a different browser!

沒落の蓅哖 2024-08-31 02:05:07
var browser = navigator.appName;
var version = navigator.appVersion;

但请注意,两者不一定反映事实。许多浏览器可以设置为与其他浏览器一样屏蔽。因此,举例来说,您无法始终确定用户是否真的使用 IE6 或冒充 IE6 的 Opera 进行冲浪。

var browser = navigator.appName;
var version = navigator.appVersion;

Note, however, that both will not necessarily reflect the truth. Many browsers can be set to mask as other browsers. So, for example, you can't always be sure if a user is actually surfing with IE6 or with Opera that pretends to be IE6.

以下是我为 Internet Explorer 自定义 CSS 的方法:

在我的 JavaScript 文件中:

function isIE () {
      var myNav = navigator.userAgent.toLowerCase();
      return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

jQuery(document).ready(function(){
    if(var_isIE){
            if(var_isIE == 10){
                jQuery("html").addClass("ie10");
            }
            if(var_isIE == 8){
                jQuery("html").addClass("ie8");
                // you can also call here some function to disable things that 
                //are not supported in IE, or override browser default styles.
            }
        }
    });

然后在我的 CSS 文件中,定义每种不同的样式:

.ie10 .some-class span{
    .......
}
.ie8 .some-class span{
    .......
}

Here is how I do custom CSS for Internet Explorer:

In my JavaScript file:

function isIE () {
      var myNav = navigator.userAgent.toLowerCase();
      return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

jQuery(document).ready(function(){
    if(var_isIE){
            if(var_isIE == 10){
                jQuery("html").addClass("ie10");
            }
            if(var_isIE == 8){
                jQuery("html").addClass("ie8");
                // you can also call here some function to disable things that 
                //are not supported in IE, or override browser default styles.
            }
        }
    });

And then in my CSS file, y define each different style:

.ie10 .some-class span{
    .......
}
.ie8 .some-class span{
    .......
}

您可以扫描用户代理来查找浏览器名称,而不是对 Web 浏览器进行硬编码:

navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+/g)[0]

我已经在 Safari、Chrome 和 Firefox 上对此进行了测试。如果您发现这在浏览器上不起作用,请告诉我。

  • Safari:"Safari"
  • Chrome:"Chrome"
  • Firefox:"Firefox"

如果需要,您甚至可以修改此设置以获取浏览器版本。请注意,有更好的方法来获取浏览器版本

navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+\/[\d.]+/g)[0].split('/')

示例输出:

Firefox/39.0    

Instead of hardcoding web browsers, you can scan the user agent to find the browser name:

navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+/g)[0]

I've tested this on Safari, Chrome, and Firefox. Let me know if you found this doesn't work on a browser.

  • Safari: "Safari"
  • Chrome: "Chrome"
  • Firefox: "Firefox"

You can even modify this to get the browser version if you want. Do note there are better ways to get the browser version

navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+\/[\d.]+/g)[0].split('/')

Sample output:

Firefox/39.0

        //IE will be identified as 'Trident' and a different version number. The name must be corrected to 'Internet Explorer' and the correct version identified.
        //ie correction
        if(/trident/i.test(M[1]))
        {
            tem = /\brv[ :]+(\d+.?\d*)/g.exec(ua) || [];
            browser = 'Internet Explorer';
            version = tem[1];
        }

        {
            tem = ua.match(/\bVersion\/(\d+.?\d*\s*\w+)/);
            browser = 'Safari';
            version = tem[1];
        }

        //If 'Chrome' is found, it may be another browser. 
        else if(M[1] === 'Chrome')
        {
            //opera

                browser = temChrome[1];
                version = temChrome[2];
            }
        }
        //There will be some odd balls, so if you wish to support those browsers, add functionality to display those browsers as well.

        if(browser == '' || version == '')
        {
            idString = 'We couldn\'t find your browser, but you can still use the site';
        }
        else
        {
            idString = browser + ' version ' + version;
        }

        alert('Your browser is ' + idString);

        //store the type of browser locally
        if(typeof(Storage) !== "undefined")
        {
            //Store
            localStorage.setItem('browser', browser);
            localStorage.setItem('version', version);
        } 
        else
        {
            alert('local storage not available');
        }
    }
)();

有了这个,它还在本地存储结果,因此不需要每次都运行此检查。

If you want a function that returns the browser as well as the version, here is an improvement from the original answer:

navigator.browserInfo = 
(
    function()
    {
        var browser = '';
        var version = '';
        var idString = '';

        var ua = navigator.userAgent;
        var tem = [];
        var M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i);

        //IE will be identified as 'Trident' and a different version number. The name must be corrected to 'Internet Explorer' and the correct version identified.
        //ie correction
        if(/trident/i.test(M[1]))
        {
            tem = /\brv[ :]+(\d+.?\d*)/g.exec(ua) || [];
            browser = 'Internet Explorer';
            version = tem[1];
        }

        //firefox
        else if(/firefox/i.test(M[1]))
        {
            tem = /\brv[ :]+(\d+.?\d*)/g.exec(ua) || [];
            browser = 'Firefox';
            version = tem[1];
        }

        //safari
        else if(/safari/i.test(M[1]))
        {
            tem = ua.match(/\bVersion\/(\d+.?\d*\s*\w+)/);
            browser = 'Safari';
            version = tem[1];
        }

        //If 'Chrome' is found, it may be another browser. 
        else if(M[1] === 'Chrome')
        {
            //opera
            var temOpr = ua.match(/\b(OPR)\/(\d+.?\d*.?\d*.?\d*)/);
            //edge
            var temEdge = ua.match(/\b(Edge)\/(\d+.?\d*)/);
            //chrome
            var temChrome = ua.match(/\b(Chrome)\/(\d+.?\d*.?\d*.?\d*)/);

            //a genuine 'Chrome' reading will result from ONLY temChrome not being null.
            var genuineChrome = temOpr == null && temEdge == null && temChrome != null;

            if(temOpr != null)
            {
                browser = temOpr[1].replace('OPR', 'Opera');
                version = temOpr[2];
            }

            if(temEdge != null)
            {
                browser = temEdge[1];
                version = temEdge[2];
            }

            if(genuineChrome)
            {
                browser = temChrome[1];
                version = temChrome[2];
            }
        }
        //There will be some odd balls, so if you wish to support those browsers, add functionality to display those browsers as well.

        if(browser == '' || version == '')
        {
            idString = 'We couldn\'t find your browser, but you can still use the site';
        }
        else
        {
            idString = browser + ' version ' + version;
        }

        alert('Your browser is ' + idString);

        //store the type of browser locally
        if(typeof(Storage) !== "undefined")
        {
            //Store
            localStorage.setItem('browser', browser);
            localStorage.setItem('version', version);
        } 
        else
        {
            alert('local storage not available');
        }
    }
)();

With this, it also stores the result locally, so this check is not necessary to run every time.

您可以使用 jQuery 库来检测浏览器版本。

示例:

jQuery.browser.version

但是,只有当您还使用 jQuery 的其他功能时,这才有意义。添加整个库只是为了检测浏览器对我来说似乎有点矫枉过正。

You could use the jQuery library to detect the browser version.

Example:

jQuery.browser.version

However, this only makes sense if you are also using other functions of jQuery. Adding an entire library just to detect the browser seems like overkill to me.
