$(function(){ 
  var mobile_flag = isMobile(); // true为PC端，false为手机端

function isMobile() { 
  var userAgentInfo = navigator.userAgent; 
 
  var mobileAgents = [ "Android", "iPhone", "SymbianOS", "Windows Phone", "iPad","iPod"]; 
 
  var mobile_flag = false; 
 
  //根据userAgent判断是否是手机 
  for (var v = 0; v < mobileAgents.length; v++) { 
      if (userAgentInfo.indexOf(mobileAgents[v]) > 0) { 
          mobile_flag = true; 
          break; 
      } 
  } 
 
   var screen_width = window.screen.width; 
   var screen_height = window.screen.height;     
 
   //根据屏幕分辨率判断是否是手机 
   if(screen_width < 500 && screen_height < 800){ 
       mobile_flag = true; 
   } 
 
   return mobile_flag;
