手机端自动跳转

　　方法1:

<SCRIPT LANGUAGE="JavaScript">
 function mobile_device_detect(url)
 {
        var thisOS=navigator.platform;
        var os=new Array("iPhone","iPod","iPad","android","Nokia","SymbianOS","Symbian","Windows Phone","Phone","Linux armv71","MAUI","UNTRUSTED/1.0","Windows CE","BlackBerry","IEMobile");
 for(var i=0;i<os.length;i++)
        {
 if(thisOS.match(os[i]))
        {  
  window.location=url;
 }
          
 }
 //因为相当部分的手机系统不知道信息,这里是做临时性特殊辨认
 if(navigator.platform.indexOf('iPad') != -1)
        {
  window.location=url;
 }
 //做这一部分是因为Android手机的内核也是Linux
 //但是navigator.platform显示信息不尽相同情况繁多,因此从浏览器下手，即用navigator.appVersion信息做判断
  var check = navigator.appVersion;
  if( check.match(/linux/i) )
          {
   //X11是UC浏览器的平台 ，如果有其他特殊浏览器也可以附加上条件
   if(check.match(/mobile/i) || check.match(/X11/i))
                 {
   window.location=url;
   } 
 }
 //类in_array函数
 Array.prototype.in_array = function(e)
 {
  for(i=0;i<this.length;i++)
  {
   if(this[i] == e)
   return true;
  }
  return false;
 }
 }
mobile_device_detect("http://m.16css.com");
