礼拜五log~js 自定义map实现方法put和get

js是很灵活的编程语言～

function Map() {    this.elements = new Array();    //向MAP中增加元素（key, value)     this.put = function(_key, _value) {        this.elements.push( {        key : _key,        value : _value        });    };    this.get = function(_key) {        try {            for (i = 0; i < this.elements.length; i++) {                if (this.elements[i].key == _key) {                    return this.elements[i].value;                }            }        } catch (e) {            return false;        }        return false;    };}
