Javascript 从js文件而不是xml文件创建关联数组

我一直在使用一个函数

getxml

，该函数创建了一个关联数组，其中包含在xml文件中找到的所有相册/曲目：

function XMLload() {
    jQuery.post(url, function(data) {
        getxml(data);
    }, 'xml');
}

function dataFromTag(node, t) {
    var d = node.getElementsByTagName(t);
    if (d.length == 0) return ('');
    return (d[0].firstChild.nodeValue);
}

jQuery(document).ready(XMLload);

var url = 'music.xml';

function getxml(xmldoc) {
xmlalbums = xmldoc.getElementsByTagName('album');

for (var i = 0; i < xmlalbums.length; i++) {
    title = dataFromTag(xmlalbums[i], 'title');
    artist = dataFromTag(xmlalbums[i], 'artist');
    artwork = dataFromTag(xmlalbums[i], 'artwork');

    var xmltracks = xmlalbums[i].getElementsByTagName('track');

    var tracks = []

    for (var j = 0; j < xmltracks.length; j++) {
        song = dataFromTag(xmltracks[j], 'title');
        mp3 = dataFromTag(xmltracks[j], 'mp3');
        tracks[song] = mp3;
    }
    albumlist[title] = [artist, artwork, tracks];
}

// call pageLoad();
pageLoad();
}

您的

var相册

有几个问题（额外的逗号，请检查以验证）。但除此之外，它还是一个有效的JSON对象

var albums=
[
    {   "title":"",
        "artist":"",
        "artwork":"",
        "tracks":[
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""}
        ]
    },
    {   "title":"",
        "artist":"",
        "artwork":"",
        "tracks":[
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
        ]
    }
];

for (var i = 0; i < albums.length; i++) {
    title = albums[i].title;
    artist = albums[i].artist;
    artwork = albums[i].artwork;

    var tracks = []

    for (var j = 0; j < albums[i].tracks.length; j++) {
        song = albums[i].tracks[j].title;
        mp3 = albums[i].tracks[j].mp3;
        tracks[song] = mp3;
    }
    albumlist[title] = [artist, artwork, tracks];
}

var相册=
[
{“标题”：“，
“艺术家”：“，
“艺术品”：“，
“轨道”：[
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}
]
},
{“标题”：“，
“艺术家”：“，
“艺术品”：“，
“轨道”：[
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
{“标题”：“，”mp3:“.mp3”，
“歌词”：“}”，
]
}
];
对于（var i=0；i

这不是JSON的作用吗？我如何用JSON重新解释代码？

var albums=
[
    {   "title":"",
        "artist":"",
        "artwork":"",
        "tracks":[
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
            {"title":"","mp3":".mp3",
            "lyrics":""},
        ]
    },
    {   "title":"",
        "artist":"",
        "artwork":"",
        "tracks":[
