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 };
