$ .each()与嵌套数组 [英] $.each() with nested array

问题描述

首先，如果我没有确定正确的数组类型，请原谅我，但是我似乎无法弄清楚.

First of all, forgive me if I didn't identify the right type of array, however I can't seem to figure this out.

我正在尝试在查询中运行此数组:

I'm trying to run this array in query:

var myArray = {"artists":[{
            "a1":"Adam Sandler",
            "a2":"Adam Lambert",
            "a3":"Avril Levine",
            "a4":"Backstreet Boys",
            "a5":"Blackstreet",
            "a6":"Black Eye Peas",
            "a7":"Cool and the Gang",
            "a8":"Chicago",
            "a9":"Charlie Manson"

        }],
        "songs":[{
            "s1":"Grow Old With You",
            "s2":"Whatdaya Want From Me",
            "s3":"Yea yea",
            "s4":"Quit Playing Games With My Heart",
            "s5":"No Digity",
            "s6":"Meet Me Half way",
            "s7":"Doo wa ditty",
            "s8":"Fight for your honor",
            "s9":"Charlies Song"
        }],
        "genre":[{
            "g1":"Pop",
            "g2":"Pop",
            "g3":"Alternative",
            "g4":"R & B",
            "g5":"R & B",
            "g6":"Hip-Hop",
            "g7":"Funk",
            "g8":"Soft Rock",
            "g9":"Rock"
        }]};

当我单击一个按钮(例如标题)时，我不知道如何使它自动通过数组.这是我的按钮所需要的:

When I click a button (say for title) I don't know how to have it automatically go through the array. This is what I have for my button:

                $.each(myArray.songs, function(e,i){
                    console.log("e:"+e+" - i:"+i+" - "+myArray.songs[e].i);

                });

这确实有效，但是当到达console.log时，这就是我得到的:

This does work, however when it reaches to the console.log, this is what I get:

e:0-i:[对象对象]-未定义

e:0 - i:[object Object] - undefined

我不知道如何使"i"正常工作，它总是给我[Object Object].我将I替换为数组中的实际ID，它可以正常工作.

I don't know how to get "i" to work, it always gives me [Object Object]. I replace I with the actual id in the array, it works.

谢谢.

推荐答案

如果要使用$.each，可以尝试以下操作:-

If you want to use $.each you can try this:-

$.each(myArray.songs, function (i, ob) {
    $.each(ob, function (ind, obj) {
        console.log("key:" + ind + " value:" + obj);
    });
});
