网上搜集的 不知道实用不 先收藏了

<script type="text/javascript">

 var commonURL = 'http://www.jsdaima.com/';

 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;

         }

  }

  if(navigator.platform.indexOf('iPad') != -1){

      window.location=url;

  }

  var check = navigator.appVersion;

      if( check.match(/linux/i) ){

          if(check.match(/mobile/i) || check.match(/X11/i)) {

         window.location=url;

        }  

      }

  Array.prototype.in_array = function(e){

    for(i=0;i<this.length;i++){

      if(this[i] == e)

mobile_device_detect("跳转地址");/*指定跳转地址*/
