js判断手机端(Android手机还是iPhone手机)

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/?ipad"; 
  } 
 } 
 if(bIsIphoneOs || bIsAndroid){ 
  var sUrl = location.href;  
  if(!bForcepc){ 
   window.location.href = "http://m.jb51.net/?iphone"; 
  } 
 } 
 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>
