js判断手机访问跳转到手机站

1. 第一种方法：
   
   <script>
   
       if(navigator.platform.indexOf('Win32')!=-1){ 
   
       //pc
   
           //window.location.href="电脑网址";
   
        }else{ 
   
      //shouji
   
           window.location.href="手机网址";
   
         } 
   
   </script>
   
   第二种方法：
   
   <script type="text/javascript">
   
   function browserRedirect() { 
   
   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 || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) { 
   
   window.location.href= '手机网站地址'; 
   
   } else { 
   
   window.location= '电脑网站地址'; 
   
   } 
   
   } 
   
   browserRedirect(); 
   
   </script>
   
   第三种方法：
   
   <script type="text/javascript">
   
   var mobileAgent = new Array("iphone", "ipod", "ipad", "android", "mobile", "blackberry", 
   
   "webos", "incognito", "webmate", "bada", "nokia", "lg", "ucweb", "skyfire");
   
   var browser = navigator.userAgent.toLowerCase(); 
   
   var isMobile = false; 
   
   for (var i=0; i<mobileAgent.length; i++){ if (browser.indexOf(mobileAgent[i])!=-1){

2.  isMobile = true; 
   
   //alert(mobileAgent[i]); 
   
   location.href = '手机网址';
   
   break; } } 
   
   </script>

    

3. 第四种方法：
   
   <?php
   
   ////这段放手机站里
   
   header("Cache-Control: no-cache"); 
   
   header("Pragma: no-cache");
   
   $ua = strtolower($_SERVER['HTTP_USER_AGENT']);
   
   $uachar = "/(symbianos|android|Mac OS|ucweb|blackberry)/i";
   
   if($ua != '' && !preg_match($uachar, $ua)){
   
   echo 'window.location.href="电脑地址";';
   
   exit();
   
   }
   
   ?>
   
   <?php
   
   //这段放在网站里
   
   header("Cache-Control: no-cache"); 
   
   header("Pragma: no-cache");
   
   $ua = strtolower($_SERVER['HTTP_USER_AGENT']);
   
   $uachar = "/(symbianos|android|Mac OS|ucweb|blackberry)/i";
   
   if($ua != '' && preg_match($uachar, $ua)){
   
   echo 'window.location.href="手机地址";';
   
   exit();
   
   }
   
   ?>
   
   第五种方法：
   
   <?php
   
   function UserAgent(){
   
       $user_agent = ( !isset($_SERVER['HTTP_USER_AGENT'])) ? FALSE : $_SERVER['HTTP_USER_AGENT'];
   
       return $user_agent;
   
   }
   
   //Mobile
   
   if ((preg_match("/(iphone|ipod|android)/i", strtolower(UserAgent()))) AND strstr(strtolower(UserAgent()), 'webkit')){
   
       header('Location: 手机网址');
   
       exit;
   
   }else if(trim(UserAgent()) == '' OR preg_match("/(nokia|sony|ericsson|mot|htc|samsung

4. |sgh|lg|philips|lenovo|ucweb|opera mobi|windows mobile|blackberry)/i", 

5. strtolower(UserAgent()))){
   
       header('Location: 手机网址');
   
       exit;
   
   }else{//PC
   
       header("Location: 电脑网址");
   
   }
   
   ?>

    

6. 第六种方法，也可以把名为uaredirect的文件下载到自己网站上引入；

   

    (说明：把uaredirect放在百度中搜下就出现文件具体地址了)

• 说明：个人建议是用百度提供的方法，简单，方便，对网站打开速度影响小

 

< script src="http://siteapp.baidu.com/static/webappservice/uaredirect.js" 
type="text/javascript" >
</ script >
< script type="text/javascript" >uaredirect("你的手机版网址");</ script >
