Javascript中的关联数组？ [英] Associative arrays in Javascript?

问题描述

目前，我正在使用以下内容在js中创建一个3d数组：

Currently, I am creating a 3d array in js using the following:

var arr = [["name1", "place1", "data1"],
          ["name2", "place2", "data2"],
          ["name3", "place3", "data3"]];

我可以使用arr [0]或arr [1]访问每个元素。但无论如何我可以使用这样的键访问它们：arr [name1]应该给我第一个。有什么建议？我想我正在寻找类似功能的Hashmap。

I can access each element using arr[0] or arr[1]. But is there anyways I can access them using a key like this: arr["name1"] should give me the first one. Any suggestions? I think I am looking for a Hashmap like functionality.

推荐答案

你能做到的唯一方法是把它包装在一个对象中。

The only way you could do that is by wrapping it in an object.

var arr = {
    name1 : ["name1", "place1", "data1"],
    name2 : ["name2", "place2", "data2"],
    name3 : ["name3", "place3", "data3"]
};
