Browser detection in JavaScript?
如何使用javascript确定确切的浏览器和版本?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | navigator.sayswho= (function(){ var ua= navigator.userAgent, tem, M= ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || []; if(/trident/i.test(M[1])){ tem= /\brv[ :]+(\d+)/g.exec(ua) || []; return 'IE '+(tem[1] || ''); } if(M[1]=== 'Chrome'){ tem= ua.match(/\b(OPR|Edge?)\/(\d+)/); if(tem!= null) return tem.slice(1).join(' ').replace('OPR', 'Opera').replace('Edg ', 'Edge '); } M= M[2]? [M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?']; if((tem= ua.match(/version\/(\d+)/i))!= null) M.splice(1, 1, tem[1]); return M.join(' '); })(); |
。
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。
我建议使用小型的javascript库bowser,是的,不是。它是基于
https://github.com/ed/bowser
你可以简单地说:
1 2 3 4 5 6 7 8 9 10 11 | 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年如何检测浏览器,包括Microsoft Edge、Safari 10和检测闪烁:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | // 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,因此它甚至覆盖了衍生浏览器,如Yandex或Vivaldi,这些浏览器实际上与它们使用的引擎的主要浏览器兼容。例外情况是Opera,它依赖于用户代理嗅探,但现在(即,ver)。15岁及以上)即使是歌剧本身也只是眨眼的贝壳。
在可能的情况下,最好避免使用特定于浏览器的代码。jquery
例如,在Opera中,您可以伪造Internet Explorer或Firefox实例。
。
有关jquery.support的详细说明,请参见:http://api.jquery.com/jquery.support/
根据jquery,现在已弃用。
We strongly recommend the use of an external library such as Modernizr

至于为什么你想知道你使用的是哪种浏览器,这是因为每种浏览器都有自己的一组错误,你最终会实现浏览器和特定版本的解决方案,或者告诉用户使用不同的浏览器!
1 2 | var browser = navigator.appName; var version = navigator.appVersion; |
然而,请注意,这两个都不一定反映出真相。许多浏览器可以设置为与其他浏览器一样屏蔽。例如,你不可能总是确定一个用户是否真的在用IE6或者假装是IE6的Opera冲浪。
这个小图书馆可以帮你。但是请注意,浏览器检测并不总是解决方案。
以下是我如何为Internet Explorer自定义CSS:
在我的javascript文件中:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | 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,Y定义了每个不同的样式:

有了这个,它还将结果存储在本地,因此不必每次都运行这个检查。
您可以扫描用户代理以查找浏览器名称,而不是对Web浏览器进行硬编码:
1 | navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+/g)[0] |

我在Safari、Chrome和Firefox上测试过。如果你发现这在浏览器上不起作用,请告诉我。
- 游猎:
"Safari" 。 - 铬:
"Chrome" 。 - 火狐:
"Firefox"
如果需要的话,您甚至可以修改它以获取浏览器版本。请注意,有更好的方法来获取浏览器版本
1 | navigator.userAgent.split(')').reverse()[0].match(/(?!Gecko|Version|[A-Za-z]+?Web[Kk]it)[A-Z][a-z]+\/[\d.]+/g)[0].split('/') |
样品输出:

可以使用jquery库检测浏览器版本。
例子:
jquery.browser.version版本
但是,只有当您还使用jquery的其他函数时,这才有意义。在我看来,添加一个完整的库来检测浏览器似乎太过分了。

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。
我做了这个小功能,希望有帮助。在这里你可以找到最新的版本浏览器检测
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 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" } |
。
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。
1 2 3 4 5 6 7 8 9 10 11 12 | $(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得IE版本
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | 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; } |
使用jquery:
1 | $.browser |
给你的感觉是:
1 | Object {chrome: true, version:"26.0.1410.63", webkit: true} |
