js判断手机或者PC的例子我们在几乎所有网站建设中都会有这段代码了，现在手机流量与pc差不多了，下面来看绵阳动力网络公司给的两段js判断手机或者PC例子吧

例子一

<script> 
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='http://www.webmy.cn'; 
  }else{ 
 //window.location.href='http://m.webmy.cn'; 
  }
 }
 $(function(){
  browserRedirect(); 
}); 
</script>

例子2

<script type="text/javascript">
 (function(){
   var reWriteUrl = function(url){
     if(url){ 
      var Splits = url.split("/"),siteName=window.location.pathname; 
      if(typeof siteName!=="undefined"){  
       return http://m.webmy.cn+siteName;   
    }   
  } 
  };   
if(/Android|webOS|iPhone|iPad|Windows Phone|iPod|BlackBerry|SymbianOS|Nokia|Mobile/i.test(navigator.userAgent)){
   var url=window.location.href;  
   var pathname=window.location.pathname;  
   if(url.indexOf("?mobile")<0){  
   try{  
     window.location.href=reWriteUrl(url);   
  }catch(e){}   
  } 
  };
 })(); 
</script>

注意，如果给搜索引擎看的话我们在文件头加入

<meta http-equiv="mobile-agent" content="format=xhtml; url=http://m.webmy.cn" />

<meta http-equiv="mobile-agent" content="format=html5; url=http://m.webmy.cn" />

意思是告诉搜索引擎移动蜘蛛抓取的是手机版本的．
