js判断终端是PC还是移动端

function IsPC()  {  
   var userAgentInfo = navigator.userAgent;  
   var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  
   var flag = true;  
   for (var v = 0; v < Agents.length; v++) {  
       if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }  
   }  
   return flag;  
}
