Edit: 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

(编辑：过期答案，ECMAScript 2015（ES6）标准javascript有一个Map实现，请在此处阅读以获取更多信息： 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);
