迅雷批量下载

1.首先介绍下js操作cookie

//写
   function setCookie(name,value)
   {
       var Days = 30;
       var exp = new Date();
       exp.setTime(exp.getTime() + Days*24*60*60*1000);
       document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
   }
   // 读
   function getCookie(name)
   {
      var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");

      if(arr=document.cookie.match(reg))

        return unescape(arr[2]);
      else
        return null;
   }
   //删
   function delCookie(name)
   {
    var exp = new Date();
    exp.setTime(exp.getTime() - 1);
    var cval=getCookie(name);
    if(cval!=null)
        document.cookie= name + "="+cval+";expires="+exp.toGMTString();
   }
JS操作cookie

可以在某个页面利用上面代码写入cookie

之后再调用迅雷。

2.调用迅雷
