我无法获取 JSON 对象中 JSON 数组的项目。我的 JSON 如下所示:
[
{
"category":9,
"channels":[
{
"id":5,
"title":"MYTITLE",
"active":true,
"recent":true,
"image":"/arts/736c1ad4-2dbe-40a6-859d-8dba89c26ec2.jpg",
"recent_tracks":{
"vip":"https://api.xyzsite.com/recent_tracks/vip-3.json",
"free":"https://api.xyzsite.com/recent_tracks/free-3.json"
},
"additional_vip_channels":[
{
"channel_name":"vip-3a",
"recent_tracks_uri":"https://api.xyzsite.com/recent_tracks/vip-3a.json",
"streams":{
"320":"http://streams.xyzsite.com/api/914/320/stream",
"64":"http://streams.xyzsite.com/api/914/64/stream",
"192":"http://streams.xyzsite.com/api/914/192/stream"
}
}
],
"streams":{
"free":"http://streams.xyzsite.com/api/31/56/stream",
"free_56":"http://streams.xyzsite.com/api/31/56/stream",
"free_128":"http://streams.xyzsite.com/api/31/128/stream",
"320":"http://streams.xyzsite.com/api/33/320/stream",
"64":"http://streams.xyzsite.com/api/33/64/stream",
"192":"http://streams.xyzsite.com/api/33/192/stream"
}
},
我使用以下代码来获取值:
$.getJSON('https://api.xyzsite.com/channels.json', function(response) {
$.each(response, function (index, value) {
var catId = value.category;
$.each(value.channels, function (index, value) {
XYZApp.channels.push({
categoryId: catId,
id: value.id,
name: value.title,
image: value.image,
recent_tracks: {
vip: value.recent_tracks.vip,
free: value.recent_tracks.free
},
streams: {
free_128: value.streams.free_128,
member_320: value.streams["320"],
member_64: value.streams["64"],
member_192: value.streams["192"]
}
});
console.log(value.additional_vip_channels);
});
});
}).
then ...
我可以获取值，但无法读取 .each jQuery 函数中的additional_vip_channels 数组。我已经尝试过了:
- value.additional_vip_channels.channel_name
- value.additional_vip_channels[0].channel_name
- value.additional_vip_channels["0"].channel_name
但它们都不起作用。
日志输出也在这里:
如何获取additional_vip_channels中的channel_name和其他数据？
最佳答案
我相信您会想要:
channels[0]['additional_vip_channels'][0]['channel_name']
同样，这应该有效:(只是选择的方式不同)
channels[0].additional_vip_channels[0].channel_name
希望有所帮助并有效:)
