JavaScript实现cookies设置，在网上有很多代码，但是功能完全的确很少找到，前段时间做ajax程序，需要js操作cookies 就自己写了段JS，这里提供给大家，希望有点用处
未加密的JS文件
/*
GetCookie(name) 获取Cookies方法 ，name为名字
SetCookie(name,value,interval,number,[path],[domain],[secure]) 设置cookies方法
name 名称，value cookies值，interval（"y" 年,"q"季,"m"月,"d"日,"h"时,"M"分,"s"秒，默认：日），number：数量级
[path],[domain],[secure] 可缺省。
DelCookie(name) 删除设置过期cookies ， name：cookies名称

function GetCookieVal(offset){
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie(name){
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen){
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return GetCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function DelCookie(name){
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires="+ exp.toGMTString();
}
function SetCookie(name, value,interval,number){
if (interval == "0") return false;
var expdate = new Date();
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = DateAdd(interval,number,expdate);
var path = (argc > 4) ? argv[4] : null;
var domain = (argc > 5) ? argv[5] : null;
var secure = (argc > 6) ? argv[6] : false;
document.cookie = name + "=" + escape (value) +((expires == null) ? "" : ("; expires="+ expires.toGMTString()))
+((path == null) ? "" : ("; path=" + path)) +((domain == null) ? "" : ("; domain=" + domain))
+((secure == true) ? "; secure" : "");
}
function DateAdd(interval,number,date){
switch(interval){
case "y":{
date.setFullYear(date.getFullYear()+number);
return date;
break;
}
case "q":{
date.setMonth(date.getMonth()+number*3);
return date;
break;
}
case "m":{
date.setMonth(date.getMonth()+number);
return date;
break;
}

date.setDate(date.getDate()+number*7);
return date;
break;

break;

date.setHours(date.getHours()+number);
return date;
break;

date.setMinutes(date.getMinutes()+number);

break;

case "s":{
date.setSeconds(date.getSeconds()+number);
return date;

case "0":{
return date;

}
}
采用脚本压缩后的JS文件（通过测试完全可以使用）
