Question

我想检测用户是否使用IE和Firefox，但我找不到脚本。

我的代码如下：

$(document).ready(function(e) {
    $.browser.chrome = /chrom(e|ium)/.test(navigator.userAgent.toLowerCase()); 
    if($.browser.chrome){
        alert(1);
             //this work well
    }
            else if(//the browser is IE){alert(2);}
            else if(//the browser is Firefox){alert(3);}

   //The problem is that I don't know how to write a script for IE and FireFox browser for chrome is work fine
 )};

Answer 1

最好的解决方案可能是：使用Modernizr。

但是，如果你一定想使用$ .browser属性，你可以使用jQuery Migrate插件（对于JQuery＆gt; = 1.9 - 在早期版本中你可以使用它），然后执行以下操作：

if($.browser.chrome) {
   alert(1);
} else if ($.browser.mozilla) {
   alert(2);
} else if ($.browser.msie) {
   alert(3);
}

如果您因某种原因需要使用navigator.userAgent，那么它将是：

$.browser.msie = /msie/.test(navigator.userAgent.toLowerCase()); 
$.browser.mozilla = /firefox/.test(navigator.userAgent.toLowerCase());

Answer 2

即检测的解决方案：

if (navigator.userAgent.match(/msie/i) || navigator.userAgent.match(/trident/i) ){
    $("html").addClass("ie");
}

需要Jquery。

Answer 3

您不应该编写自己的浏览器检测代码 - 之前已经多次完成。请使用Modernizr来检测独立的浏览器功能。检测各种功能比检测整个浏览器更好，因为各种浏览器可能支持不同的功能集，而这些功能甚至可能通过同一浏览器的各种版本进行更改。如果您检测到某个特定功能的存在，您的代码可能会在更多浏览器中更好地工作。对于各种移动浏览器尤其如此。

当您运行Modernizr时，它会更新您的HEAD元素的class属性，以便列出您正在使用的浏览器的各种功能 - 然后您可以使用Javascript查询属性并确定如果某个功能存在（或缺失）该怎么办。

使用此：

(function (factory) {
  if (typeof define === 'function' && define.amd) {
    // AMD. Register as an anonymous module.
    define(['jquery'], function ($) {
      return factory($);
    });
  } else if (typeof module === 'object' && typeof module.exports === 'object') {
    // Node-like environment
    module.exports = factory(require('jquery'));
  } else {
    // Browser globals
    factory(window.jQuery);
  }
}(function(jQuery) {
  "use strict";

  function uaMatch( ua ) {
    // If an UA is not provided, default to the current browser UA.
    if ( ua === undefined ) {
      ua = window.navigator.userAgent;
    }
    ua = ua.toLowerCase();

    var match = /(edge)\/([\w.]+)/.exec( ua ) ||
        /(opr)[\/]([\w.]+)/.exec( ua ) ||
        /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
        /(version)(applewebkit)[ \/]([\w.]+).*(safari)[ \/]([\w.]+)/.exec( ua ) ||
        /(webkit)[ \/]([\w.]+).*(version)[ \/]([\w.]+).*(safari)[ \/]([\w.]+)/.exec( ua ) ||
        /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
        /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
        /(msie) ([\w.]+)/.exec( ua ) ||
        ua.indexOf("trident") >= 0 && /(rv)(?::| )([\w.]+)/.exec( ua ) ||
        ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
        [];

    var platform_match = /(ipad)/.exec( ua ) ||
        /(ipod)/.exec( ua ) ||
        /(iphone)/.exec( ua ) ||
        /(kindle)/.exec( ua ) ||
        /(silk)/.exec( ua ) ||
        /(android)/.exec( ua ) ||
        /(windows phone)/.exec( ua ) ||
        /(win)/.exec( ua ) ||
        /(mac)/.exec( ua ) ||

        /(playbook)/.exec( ua ) ||
        /(bb)/.exec( ua ) ||
        /(blackberry)/.exec( ua ) ||
        [];

    var browser = {},
        matched = {
          browser: match[ 5 ] || match[ 3 ] || match[ 1 ] || "",
          version: match[ 2 ] || match[ 4 ] || "0",
          versionNumber: match[ 4 ] || match[ 2 ] || "0",
          platform: platform_match[ 0 ] || ""
        };

    if ( matched.browser ) {
      browser[ matched.browser ] = true;
      browser.version = matched.version;
      browser.versionNumber = parseInt(matched.versionNumber, 10);
    }

    if ( matched.platform ) {
      browser[ matched.platform ] = true;
    }

    // These are all considered mobile platforms, meaning they run a mobile browser
    if ( browser.android || browser.bb || browser.blackberry || browser.ipad || browser.iphone ||
      browser.ipod || browser.kindle || browser.playbook || browser.silk || browser[ "windows phone" ]) {
      browser.mobile = true;
    }

    // These are all considered desktop platforms, meaning they run a desktop browser
    if ( browser.cros || browser.mac || browser.linux || browser.win ) {
      browser.desktop = true;
    }

    // Chrome, Opera 15+ and Safari are webkit based browsers
    if ( browser.chrome || browser.opr || browser.safari ) {
      browser.webkit = true;
    }

    // IE11 has a new token so we will assign it msie to avoid breaking changes
    // IE12 disguises itself as Chrome, but adds a new Edge token.
    if ( browser.rv || browser.edge ) {
      var ie = "msie";

      matched.browser = ie;
      browser[ie] = true;
    }

    // Blackberry browsers are marked as Safari on BlackBerry
    if ( browser.safari && browser.blackberry ) {
      var blackberry = "blackberry";

      matched.browser = blackberry;
      browser[blackberry] = true;
    }

    // Playbook browsers are marked as Safari on Playbook
    if ( browser.safari && browser.playbook ) {
      var playbook = "playbook";

      matched.browser = playbook;
      browser[playbook] = true;
    }

    // BB10 is a newer OS version of BlackBerry
    if ( browser.bb ) {
      var bb = "blackberry";

      matched.browser = bb;
      browser[bb] = true;
    }

    // Opera 15+ are identified as opr
    if ( browser.opr ) {
      var opera = "opera";

      matched.browser = opera;
      browser[opera] = true;
    }

    // Stock Android browsers are marked as Safari on Android.
    if ( browser.safari && browser.android ) {
      var android = "android";

      matched.browser = android;
      browser[android] = true;
    }

    // Kindle browsers are marked as Safari on Kindle
    if ( browser.safari && browser.kindle ) {
      var kindle = "kindle";

      matched.browser = kindle;
      browser[kindle] = true;
    }

     // Kindle Silk browsers are marked as Safari on Kindle
    if ( browser.safari && browser.silk ) {
      var silk = "silk";

      matched.browser = silk;
      browser[silk] = true;
    }

    // Assign the name and platform variable
    browser.name = matched.browser;
    browser.platform = matched.platform;
    return browser;
  }

  // Run the matching process, also assign the function to the returned object
  // for manual, jQuery-free use if desired
  window.jQBrowser = uaMatch( window.navigator.userAgent );
  window.jQBrowser.uaMatch = uaMatch;

  // Only assign to jQuery.browser if jQuery is loaded
  if ( jQuery ) {
    jQuery.browser = window.jQBrowser;
  }

  return window.jQBrowser;
}));

尝试使用它

$(document).ready(function() {
// If the browser type if Mozilla Firefox
if ($.browser.mozilla && $.browser.version >= "1.8" ){ 
// some code
}
// If the browser type is Opera
if( $.browser.opera)
{
// some code
}
// If the web browser type is Safari
if( $.browser.safari )
{
// some code
}
// If the web browser type is Chrome
if( $.browser.chrome)
{
// some code
}
// If the web browser type is Internet Explorer
if ($.browser.msie && $.browser.version <= 6 )
{
// some code
}
//If the web browser type is Internet Explorer 6 and above
if ($.browser.msie && $.browser.version > 6)
{
// some code
}
});

Answer 6

您可以使用此代码找到正确的浏览器，并且可以为任何目标浏览器进行更改.....

onCreate

function myFunction() { 
        if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 ){
            alert('Opera');
        }
        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 )){
          alert('IE'); 
        }  
        else{
           alert('unknown');
        }
    }

Answer 7

$.browser.chrome = /chrom(e|ium)/.test(navigator.userAgent.toLowerCase()); 

if($.browser.chrome){
  alert(1);      
}

更新：（10x to @Mr.Bacciagalupe）

jQuery已从 1.9 及其最新版本中删除了$.browser。

但你仍然可以使用$ .browser作为独立的插件，找到here

我已经使用了它，它适用于我。还包括jquery迁移插件和jquery文件。

if ( $.browser.webkit ) {
alert( "This is WebKit!" );
}
