哈希映射

//定义一个Hash Map

var hashMap={

Set : function(key,value){this[key] = value},

Get : function(key){return this[key]},

Contains : function(key){return this.Get(key) == null?false:true},

Remove : function(key){delete this[key]}

}

//设置hashMap键值

hashMap.Set("name","bonly");

hashMap.Set("age","24");

//获取hashMap值

hashMap.Get("name");//bonly

hashMap.Contains("title");//false

hashMap.Contains("name");//true

hashMap.Remove("age");
