网上常用的代码

/** * [isMobile 判断平台] * @param test: 0:iPhone 1:Android */ function ismobile(test){ var u = navigator.userAgent, app = navigator.appVersion; if(/AppleWebKit.*Mobile/i.test(navigator.userAgent) || (/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/.test(navigator.userAgent))){ if(window.location.href.indexOf("")<0){ try{ if(/iPhone|mac|iPod|iPad/i.test(navigator.userAgent)){ return '0'; }else{ return '1'; } }catch(e){} } }else if( u.indexOf('iPad') > -1){ return '0'; }else{ return '1'; } };

使用方法：

var pla=ismobile(1);

如果pla返回的是0:iPhone 1:Android

代码一、

<script type="text/javascript"> var browser = { versions: function () { var u = navigator.userAgent, app = navigator.appVersion; return {//移动终端浏览器版本信息 trident: u.indexOf('Trident') > -1, //IE内核 presto: u.indexOf('Presto') > -1, //opera内核 webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核 gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核 mobile: !!u.match(/AppleWebKit.*Mobile/i) || !!u.match(/MIDP|SymbianOS|NOKIA|SAMSUNG|LG|NEC|TCL|Alcatel|BIRD|DBTEL|Dopod|PHILIPS|HAIER|LENOVO|MOT-|Nokia|SonyEricsson|SIE-|Amoi|ZTE/), //是否为移动终端 ios: !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端 android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器 iPhone: u.indexOf('iPhone') > -1 || u.indexOf('Mac') > -1, //是否为iPhone或者QQHD浏览器 iPad: u.indexOf('iPad') > -1, //是否iPad webApp: u.indexOf('Safari') == -1 //是否web应该程序，没有头部与底部 }; } (), language: (navigator.browserLanguage || navigator.language).toLowerCase() } if (browser.versions.iPhone || browser.versions.iPad || browser.versions.ios) { window.location.href = "http://www.jb51.net"; } if (browser.versions.android) { window.location.href = "http://www.qq.com"; } </script>

如何判断是否是 iPad 浏览器呢，关键是看它的 User Agent 中是否有 iPad。iPad 使用的是 Safari Mobile 浏览器，他的的 User Agent 是：

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

Javascript代码

function is_iPad(){

var ua = navigator.userAgent.toLowerCase();

if(ua.match(/iPad/i)=="ipad") {

return true;

} else {

return false;

}

}

因此，判断ipad,iphone,android的代码为：

<script type="text/javascript"> var bForcepc = fGetQuery("dv") == "pc"; function fBrowserRedirect(){ var sUserAgent = navigator.userAgent.toLowerCase(); var bIsIpad = sUserAgent.match(/ipad/i) == "ipad"; var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os"; var bIsMidp = sUserAgent.match(/midp/i) == "midp"; var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4"; var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb"; var bIsAndroid = sUserAgent.match(/android/i) == "android"; var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce"; var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile"; if(bIsIpad){ var sUrl = location.href; if(!bForcepc){ window.location.href = "http://m.jb51.net/"; } } if(bIsIphoneOs || bIsAndroid){ var sUrl = location.href; if(!bForcepc){ window.location.href = "http://m.jb51.net/"; } } if(bIsMidp||bIsUc7||bIsUc||bIsCE||bIsWM){ var sUrl = location.href; if(!bForcepc){ window.location.href = "http://m.jb51.net/"; } } } function fGetQuery(name){//获取参数值 var sUrl = window.location.search.substr(1); var r = sUrl.match(new RegExp("(^|&)" + name + "=([^&]*)(&|$)")); return (r == null ? null : unescape(r[2])); } function fShowVerBlock(){ if(bForcepc){ document.getElementById("dv_block").style.display = "block"; } else{ document.getElementById("ad_block").style.display = "block"; } } fBrowserRedirect(); </script>
