JS判斷瀏覽器

1.js判斷PC瀏覽器

<script type="text/javascript">var Sys = {};var ua = navigator.userAgent.toLowerCase();var s;(s = ua.match(/msie ([\d.]+)/)) ? Sys.ie = s[1] :(s = ua.match(/firefox\/([\d.]+)/)) ? Sys.firefox = s[1] :(s = ua.match(/chrome\/([\d.]+)/)) ? Sys.chrome = s[1] :(s = ua.match(/opera.([\d.]+)/)) ? Sys.opera = s[1] :(s = ua.match(/version\/([\d.]+).*safari/)) ? Sys.safari = s[1] : 0;//以下進行測試if (Sys.ie) document.write('IE: ' + Sys.ie);if (Sys.firefox) document.write('Firefox: ' + Sys.firefox);if (Sys.chrome) document.write('Chrome: ' + Sys.chrome);if (Sys.opera) document.write('Opera: ' + Sys.opera);if (Sys.safari) document.write('Safari: ' + Sys.safari);</script>

2.js判斷手機移動終端

<script type="text/javascript">/** 智能機瀏覽器版本資訊:**/var browser={versions:function(){ var u = navigator.userAgent, app = navigator.appVersion; return {//移動終端瀏覽器版本資訊 trident: u.indexOf('Trident') > -1, //IE核心presto: u.indexOf('Presto') > -1, //opera核心webKit: u.indexOf('AppleWebKit') > -1, //蘋果、Google核心gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //Firefox核心mobile: !!u.match(/AppleWebKit.*Mobile.*/)||!!u.match(/AppleWebKit/), //是否為移動終端ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios終端android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android終端或者uc瀏覽器iPhone: u.indexOf('iPhone') > -1 || u.indexOf('Mac') > -1, //是否為iPhone或者QQHD瀏覽器iPad: u.indexOf('iPad') > -1, //是否iPadwebApp: u.indexOf('Safari') == -1 //是否web應該程式，沒有頭部與底部};}(),language:(navigator.browserLanguage || navigator.language).toLowerCase()} document.writeln("語言版本: "+browser.language);document.writeln(" 是否為移動終端: "+browser.versions.mobile);document.writeln(" ios終端: "+browser.versions.ios);document.writeln(" android終端: "+browser.versions.android);document.writeln(" 是否為iPhone: "+browser.versions.iPhone);document.writeln(" 是否iPad: "+browser.versions.iPad);document.writeln(navigator.userAgent);</script>
