如何使用JavaScript / JQuery创建简单的地图
问题描述：
如何创建这个Java代码的JavaScript / JQuery等价物：
How can you create the JavaScript/JQuery equivalent of this Java code:
Map map = new HashMap(); //Doesn't not have to be a hash map, any key/value map is fine
map.put(myKey1, myObj1);
map.put(myKey2, myObj2); //Repeat n times
function Object get(k) {
return map.get(k);
}

编辑：过时的答案，ECMAScript 2015（ES6）标准JavaScript有一个Map实现，请阅读这里获得更多信息： https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map
Out of date answer, ECMAScript 2015 (ES6) standard javascript has a Map implementation, read here for more info: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map
var map = new Object(); // or var map = {};
map[myKey1] = myObj1;
map[myKey2] = myObj2;
function get(k) {
return map[k];
}
//map[myKey1] == get(myKey1);
