Javascript 如何从序列化数组中获取数据？,javascript,jquery,json,Javascript,Jquery,Json,请帮助我将值打印到控制台和字段“昵称”的键。以下是JSON中的序列化数据数组： [ {"fields": {"user_permissions": [], "nickname": "\u0418\u0432\u0430\u043d \u0422\u0443\u0440\u0433\u0435\u043d\u0435\u0432 \u0451\u043f\u0442\u0430", "groups": [], "avatar": "", "gender": 1, "skype": "dfs

请帮助我将值打印到控制台和字段“昵称”的键。以下是JSON中的序列化数据数组：

[
    {"fields": {"user_permissions": [], "nickname": "\u0418\u0432\u0430\u043d \u0422\u0443\u0440\u0433\u0435\u043d\u0435\u0432 \u0451\u043f\u0442\u0430", "groups": [], "avatar": "", "gender": 1, "skype": "dfsdf", "other": "zzzz", "phone": "2014-0921"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 4}, 
    {"fields": {"user_permissions": [], "nickname": "\u0410\u043d\u0442\u043e\u043d \u0427\u0435\u0445", "groups": [], "avatar": "", "gender": 2, "skype": "dfsdf", "other": "qqqqqq", "phone": "21"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 5}
]

我希望结果是这样的：

0: zzzzzz
1: qqqqqq

我该怎么做呢？

您在问题中提出的数组是。此外，

username

在给定数组中的任何对象中都没有字段

如果您是指每个

字段

对象中的

其他

字段，则可以使用

数组.map

检索该字段：

var usernames = [
    {"fields": {"user_permissions": [], "nickname": "\u0418\u0432\u0430\u043d \u0422\u0443\u0440\u0433\u0435\u043d\u0435\u0432 \u0451\u043f\u0442\u0430", "groups": [], "avatar": "", "gender": 1, "skype": "dfsdf", "other": "zzzz", "phone": "2014-0921"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 4}, 
    {"fields": {"user_permissions": [], "nickname": "\u0410\u043d\u0442\u043e\u043d \u0427\u0435\u0445", "groups": [], "avatar": "", "gender": 2, "skype": "dfsdf", "other": "qqqqqq", "phone": "21"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 5}
].map(function (v) { return v.fields.other });
//=> usernames now: ["zzzz", "qqqqqq"]

…

< p>如果要打印索引和昵称，请考虑使用Frace:

var users = [
    {"fields": {"user_permissions": [], "nickname": "\u0418\u0432\u0430\u043d \u0422\u0443\u0440\u0433\u0435\u043d\u0435\u0432 \u0451\u043f\u0442\u0430", "groups": [], "avatar": "", "gender": 1, "skype": "dfsdf", "other": "zzzz", "phone": "2014-0921"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 4}, 
    {"fields": {"user_permissions": [], "nickname": "\u0410\u043d\u0442\u043e\u043d \u0427\u0435\u0445", "groups": [], "avatar": "", "gender": 2, "skype": "dfsdf", "other": "qqqqqq", "phone": "21"}, "model": "app_accounts.userprofile_deferred_avatar_date_joined_email_fic679ed35161c7ba80f007b4235db5148", "pk": 5}
] 

users.forEach(function(users, index) {console.log(index + ': ' + users.fields.nickname);});

将打印：

0: Иван Тургенев ёпта
1: Антон Чех

你期待吗？

你的json没有字段

“用户名”

对不起。字段名“昵称”@dert：首先需要将JSON解析为JavaScript对象

var parsed=JSON.parse（JSON_数据）

。然后获取结果，并像普通数组一样迭代它<代码>for（var i=0；i
