JS 自定义字典对象

  <script type="text/javascript" language="javascript">
//自定义字典对象
function Dictionary(){
 this.data ={};
 
 this.put = function(key,value){
  this.data[key] = value;
 };

 this.get = function(key){
  return this.data[key];
 };

//使用 例子
var d = new Dictionary();
d.put("CN",{id:1,name:‘df‘});
d.put("US", "America");
document.write(d.get("CN").name);
document.write(d.get("US"));


var dic={};

dic["b"]={id:1,name:"wqeqweqwewqe"}
