JavaScript前端实现手机端访问自动跳转的三种方案

作者：半夏时间：2026-10-21 21:27:10浏览：410

本文介绍了在JavaScript前端开发中判断用户是否使用手机设备并自动跳转至移动端页面的三种常见实现方式。通过检测navigator.userAgent识别iPad、iPhone、Android等设备类型，结合window.location.href实现页面重定向。代码示例涵盖了基础跳转逻辑、腾讯风格判断及带PC强制切换功能的完整方案，适用于需要区分桌面与移动端的Web应用场景。

常用跳转代码实现

常用的页面跳转实现代码

基础跳转逻辑


<script type="text/javascript">
 // borwserRedirect
 (function browserRedirect(){
  var sUserAgent = navigator.userAgent.toLowerCase();
  var bIsIpad = sUserAgent.match(/ipad/i) == 'ipad';
  var bIsIphone = 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) == 'web';
  var bIsCE = sUserAgent.match(/windows ce/i) == 'windows ce';
  var bIsWM = sUserAgent.match(/windows mobile/i) == 'windows mobile';
  var bIsAndroid = sUserAgent.match(/android/i) == 'android';
  if(bIsIpad || bIsIphone || bIsMidp || bIsUc7 || bIsUc || bIsCE || bIsWM || bIsAndroid ){
  window.location.href = '跳转的移动端网址';
  }
 })();
 </script>
<script type="text/javascript"> 
<!-- 
  //平台、设备和操作系统 
  var system = { 
   win: false, 
   mac: false, 
   xll: false, 
   ipad:false 
  }; 
  //检测平台 
  var p = navigator.platform; 
  system.win = p.indexOf("Win") == 0; 
  system.mac = p.indexOf("Mac") == 0; 
  system.x11 = (p == "X11") || (p.indexOf("Linux") == 0); 
  system.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false; 
  //跳转语句，如果是手机访问就自动跳转到wap.baidu.com页面 
  if (system.win || system.mac || system.xll||system.ipad) { 
  } else { 
   window.location.href = "http://www.jdpatro.com/3g/"; 
  } 
--> 
</script>

腾讯风格跳转示例

腾讯风格的设备跳转逻辑示例

腾讯设备检测代码


<script type="text/javascript">
if(window.location.toString().indexOf('pref=padindex') != -1){
}else{
 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("?mobile")<0){
  try{
   if(/Android|Windows Phone|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent)){
    window.location.href="http://xw.qq.com/index.htm";
   }else if(/iPad/i.test(navigator.userAgent)){
    //window.location.href="http://www.qq.com/pad/"
   }else{
    window.location.href="http://xw.qq.com/simple/s/index/"
   }
  }catch(e){}
 }
 }
}
</script>
<script type="text/javascript"> 
<!-- 
  //平台、设备和操作系统 
  var system = { 
   win: false, 
   mac: false, 
   xll: false, 
   ipad:false 
  }; 
  //检测平台 
  var p = navigator.platform; 
  system.win = p.indexOf("Win") == 0; 
  system.mac = p.indexOf("Mac") == 0; 
  system.x11 = (p == "X11") || (p.indexOf("Linux") == 0); 
  system.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false; 
  //跳转语句，如果是手机访问就自动跳转到wap.baidu.com页面 
  if (system.win || system.mac || system.xll||system.ipad) { 
  } else { 
   window.location.href = "http://www.jdpatro.com/3g/"; 
  } 
--> 
</script>

客户端类型判断方法

利用JavaScript判断浏览器客户端类型（包括iPad、iPhone、Android等）

完整判断与PC切换代码


<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://ipad.mail.163.com/"; 
   } 
  } 
  if(bIsIphoneOs || bIsAndroid){ 
   var sUrl = location.href;  
   if(!bForcepc){ 
    window.location.href = "http://smart.mail.163.com/"; 
   } 
  } 
  if(bIsMidp||bIsUc7||bIsUc||bIsCE||bIsWM){ 
   var sUrl = location.href;  
   if(!bForcepc){ 
    window.location.href = "http://m.mail.163.com/"; 
   } 
  } 
 } 
 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 : (r[2])); 
 } 
 function fShowVerBlock(){  
  if(bForcepc){ 
   document.getElementByIdx_x("dv_block").style.display = "block"; 
  } 
  else{ 
   document.getElementByIdx_x("ad_block").style.display = "block"; 
  } 
 } 
 fBrowserRedirect(); 
 </script>
