在Javascript中推送到2D数组-Pushto2DArraysinJavascript

I am trying to understand how 2D Arrays should work in Javascript, where I am currently attempting to store data in categories. In this scenario, I have a list of maps such as...

我试图了解2D数组应如何在Javascript中工作,我目前正在尝试将数据存储在类别中。在这种情况下,我有一个地图列表,如...

arena_badlands
arena_dust
ctf_2fort
cp_dustbowl

I would like to create a 2D Array where they are categorized by the types (arena, ctf, cp) so I can handle the data more efficiently. For whatever reason, I am unable to use the push() method as expected. Can anyone please help share what it is that I am doing incorrectly?

我想创建一个2D数组,它们按类型(竞技场,ctf,cp)进行分类,这样我就可以更有效地处理数据。无论出于何种原因,我无法按预期使用push()方法。谁能帮助分享我做错了什么?

As the maps in the list won't necessarily be in order by type, it keeps me from creating a single array of arena maps and then placing this inside of availableMaps.

由于列表中的地图不一定按类型排序,因此它不会创建单个竞技场地图数组,然后将其放在availableMaps中。

var availableMaps = [[]];       // Store all maps on the server which can be loaded

function getMaps()
{
    $.ajax({
        type: "POST",
        url: "handler.php",
        data: { 'action': 'getMaps' },
        dataType: 'json',
        success: function(data)
        {
            var maps = data['maps'];
            var counter = 0;

            $.each( maps, function( key, value )
            {
                // Split map name to fetch the type (ex: arena_badlands would be an 'arena' map)
                var parts = value.split("_");
                var mapType = parts[0];

                availableMaps[mapType][counter].push(value);

                counter++;
            });
        }
    });
}

var inputs = ["arena_badlands", "arena_dust", "ctf_2fort", "cp_dustbowl"];

function getAvailableMaps(inputs) {
    var map = {}, parts, name, item, items;
    for (var i = 0; i 

var inputs = ["arena_badlands", "arena_dust", "ctf_2fort", "cp_dustbowl"];

function getAvailableMaps(inputs) {
    var map = {}, input, name, item, items;
    for (var i = 0, i2; i
