废话不多说了，直接给大家贴代码了，本文写的不好还请各位大侠见谅。
JScript code：
function Cookie(key,value)
{
this.key=key;
if(value!=null)
{
this.value=escape(value);
}
this.expiresTime=null;
this.domain=null;
this.path="/";
this.secure=null;
}
Cookie.prototype.setValue=function(value){this.value=escape(value);}
Cookie.prototype.getValue=function(){return (this.value);}
Cookie.prototype.setExpiresTime=function(time){this.expiresTime=time;}
Cookie.prototype.getExpiresTime=function(){return this.expiresTime;}
Cookie.prototype.setDomain=function(domain){this.domain=domain;}
Cookie.prototype.getDomain=function(){return this.domain;}
Cookie.prototype.setPath=function(path){this.path=path;}
Cookie.prototype.getPath=function(){return this.path;}
Cookie.prototype.Write=function(v)
{
if(v!=null)
{
this.setValue(v);
}
var ck=this.key+"="+this.value;
if(this.expiresTime!=null)
{
try
{
ck+=";expires="+this.expiresTime.toUTCString();;
}
catch(err)
{
alert("expiresTime参数错误");
}
}
if(this.domain!=null)
{
ck+=";domain="+this.domain;
}
if(this.path!=null)
{
ck+=";path="+this.path;
}
if(this.secure!=null)
{
ck+=";secure";
}
document.cookie=ck;
}
Cookie.prototype.Read=function()
{
try
{
var cks=document.cookie.split("; ");
var i=0;
for(i=0;i <cks.length;i++)
{
var ck=cks[i];
var fields=ck.split("=");
if(fields[0]==this.key)
{
this.value=fields[1];
return (this.value);
}
}
return null;
}
catch(err)
{
alert("cookie读取错误");
return null;
}
}
