 }

 // 设置cookie，同一域名都可获取
 function setCookie(name, value, exdays) {
   var exdays = exdays || 1024;
   var d = new Date();
   d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
   document.cookie = name + "=" + escape(value) + ";path=/;expires=" + d.toGMTString();
 }
 // 读取cookies，判断是否存在设置的name
 function getCookie(name) {
   var name = name + "=";
   var ca = document.cookie.split(';');
   for (var i = 0; i < ca.length; i++) {
     var c = ca[i].trim();
     if (c.indexOf(name) == 0) {
       return c.substring(name.length, c.length);
     }
   }
   return "";
