Copy code The code is as follows:

/*
* Js Class Cookie
* Author:Mr Co
*/
var Cookie = function(/*Cookie name*/name){
this.$name = name;
var allcookies = document.cookie;
if(allcookies == '') return;
var cookies = allcookies.split(';');
var cookie = null;

if(cookies[i].substring(0,name.length 1) == (name '=')){

break;
}
}
if(cookie == null) return;
var cookieval = cookie.substring(name.length 1);
var a = cookieval.split('&');
for(var i = 0; i < a.length; i ){

}
for(var i = 0; i < a.length; i ){

}
}
