复制代码 代码如下:

function $Cookie(){

var a=arguments.callee;

var b=a._cached;

if(a._cached){return a._cached}

if(!(this instanceof a)){return new a}

if(typeof a._cached=="undefined"){a._cached=this}

}

$Cookie.prototype.get=function(e){

var a=document.cookie.split(/s*;s*/);

var d=new RegExp("^(s*"+e+"s*=)");

for(var b=0;b<a.length;b++){

if(d.test(a[b])){return unescape(a[b].substr(RegExp.$1.length))}

}

return null

};

$Cookie.prototype.set=function(e,f,d,a){

var b="";

if(typeof d=="number"){b=";expires="+(new Date((new Date()).getTime()+d*1000*60*60*24)).toGMTString()}

if(typeof a=="undefined"){a=""}

document.cookie=e+"="+escape(f)+b+"; path=/"+(a?"; domain="+a:"");

return this

};

$Cookie.prototype.remove=function(a){

if(this.get(a)!=null){this.set(a,"",-1)}

return this

};
