用例：

cookie = new cookie;

cookie.set('text1','123');

cookie.set('text2','321',3600*24);

text2 = cookie.get('text2');

cookie.del('text2');

cookie.setlifetime(3600*24*2);

cookie.set('text3','456');

alert(cookie.getall());

cookie.js——

var cookie = cookie || function(){

   cookies = document.cookie.split('; ');
   for (i in cookies){
       cookie = cookies[i].split('=');
       this.cookies[cookie[0]] = cookie[1];
   }
   this.date = new Date();//日期初始化
}
cookie.prototype = {
   cookies:[],//cookie值存储器
   lifetime:null,//生命周期存储器,单位毫秒
   date:null,//日期存储器
   setlifetime:function(lifetime){
       if (lifetime = parseInt(lifetime)){
           this.lifetime = lifetime;
       }
       return this;
   },
   get:function(name){
       if (this.cookies[name]){
           return this.cookies[name];
       }else{
           return false;
       }
   },
   getall:function(){
       return document.cookie;
   },
   set:function(name,value,lifetime){
       cookieText = name+'='+value+';';
       lifetime = lifetime || this.lifetime;
       if (lifetime = parseInt(lifetime)){
           this.date.setTime(this.date.getTime()+lifetime*1000);
           cookieText += 'expires='+this.date.toGMTString();
       }
       document.cookie = cookieText;
       return this;
   },
   del:function(name){
       if (this.cookies[name]){
           this.date.setTime(this.date.getTime()-10000);
           document.cookie = name+'=;expires='+this.date.toGMTString();
       }
       return this;
   }
};
