浏览器检测是在工作中经常用到的,如果只是简单判断当前是什么浏览器的话可以通过window.navigator.useragent这样的js来直接判断就可以了!
但是针对浏览器版本要求比较高的时候,如果只是单纯的判断浏览器的名字的话还不能解决问题,这时候就要通过其他方式来实现!现有的jquery已经废弃了$.browser的使用,所以在这里我介绍一个叫做"浏览器嗅探器"的程序来实现!
代码如下:(BrowserDetect.js)
var BrowserDetect = { init: function () { this.browser = this.searchString(this.dataBrowser) || "An unknown browser"; this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) || "an unknown version"; this.OS = this.searchString(this.dataOS) || "an unknown OS"; }, searchString: function (data) { for (var i=0;i<data.length;i++) { var dataString = data[i].string; var dataProp = data[i].prop; this.versionSearchString = data[i].versionSearch || data[i].identity; if (dataString) { if (dataString.indexOf(data[i].subString) != -1) return data[i].identity; } else if (dataProp) return data[i].identity; } }, searchVersion: function (dataString) { var index = dataString.indexOf(this.versionSearchString); if (index == -1) return; return parseFloat(dataString.substring(index+this.versionSearchString.length+1)); }, dataBrowser: [ { string: navigator.userAgent, subString: "Chrome", identity: "Chrome" }, { string: navigator.userAgent, subString: "OmniWeb", versionSearch: "OmniWeb/", identity: "OmniWeb" }, { string: navigator.vendor, subString: "Apple", identity: "Safari", versionSearch: "Version" }, { prop: window.opera, identity: "Opera" }, { string: navigator.vendor, subString: "iCab", identity: "iCab" }, { string: navigator.vendor, subString: "KDE", identity: "Konqueror" }, { string: navigator.userAgent, subString: "Firefox", identity: "Firefox" }, { string: navigator.vendor, subString: "Camino", identity: "Camino" }, { // for newer Netscapes (6+) string: navigator.userAgent, subString: "Netscape", identity: "Netscape" }, { string: navigator.userAgent, subString: "MSIE", identity: "Internet Explorer", versionSearch: "MSIE" }, { string: navigator.userAgent, subString: "Gecko", identity: "Mozilla", versionSearch: "rv" }, { // for older Netscapes (4-) string: navigator.userAgent, subString: "Mozilla", identity: "Netscape", versionSearch: "Mozilla" } ], dataOS : [ { string: navigator.platform, subString: "Win", identity: "Windows" }, { string: navigator.platform, subString: "Mac", identity: "Mac" }, { string: navigator.userAgent, subString: "iPhone", identity: "iPhone/iPod" }, { string: navigator.platform, subString: "Linux", identity: "Linux" } ] }; BrowserDetect.init();
使用方式如下:
BrowserDetect.browser;// 浏览器的名称,例如Firefox,IE BrowserDetect.version;//浏览器的版本,比如,7、11 BrowserDetect.OS;//浏览器所宿主的操作系统,比如Windows、Linux
这个js兼容非常不错!使用起来比较简单,而且功能强大!
