js determines the mobile phone (Android phone or iPhone phone)_javascript skills

Commonly used codes on the Internet

/**
 * [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("&#63;mobile")<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';
	}
};

How to use:

var pla=ismobile(1);

If pla returns 0:iPhone 1:Android

Code 1,

<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;)&#63; 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";
}

How to determine whether it is an iPad browser? The key is to see if there is an iPad in its User Agent. The iPad uses the Safari Mobile browser, and its User Agent is:

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 code
function is_iPad(){
var ua = navigator.userAgent.toLowerCase();
if(ua.match(/iPad/i)=="ipad") {
return true;
} else {
return false;
}
}
Therefore, the code to determine ipad, iphone, android is:

<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/&#63;ipad"; 
 } 
 } 
 if(bIsIphoneOs || bIsAndroid){ 
 var sUrl = location.href; 
 if(!bForcepc){ 
  window.location.href = "http://m.jb51.net/&#63;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 &#63; 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>
