Question

请帮我打印控制台的值和“昵称”字段的键。这是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？

Answer 1

您在问题中提供的数组是not serialized。此外username给定数组中的任何对象都没有字段。

如果您指的是每个other对象中的字段fields，则可以使用Array.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"]

如果要打印索引和昵称，请考虑使用forEach：

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
