javascript - 无法从对象中获取数据

问题描述

我有 java 脚本对象，我想从对象中获取值，但我无法从对象中获取值。

这是我的 javascript 对象

var profile = { '[Profile ID]': 135675302,
  '[Name | Prefix]': '',
  '[Name | First]': 'KK',
  '[Name | Middle]': '',
  '[Name | Last]': 'Test',
  '[Contact Name]': 'KK Test',
  '[Email | Primary]': 'kk@yopmail.com',
  '[Email | Main]': 'kk@yopmail.com',
  '[Address | Primary | Line 1]': '',
  '[Address | Primary | Line 2]': '',
  '[Address | Primary | City]': '',
  '[Address | Primary | State]': '',
  '[Address | Primary | Zip]': '',
  '[Address | Primary | Country]': '',
  '[Address | Main | Line 1]': '',
  '[Address | Main | Line 2]': '',
  '[Address | Main | City]': '',
  '[Address | Main | State]': '',
  '[Address | Main | Zip]': '',
  '[Address | Main | Country]': '',
  '[Phone | Primary]': '',
  '[Organization]': '',
  '*Key Contact': '',
  Facebook: '',
  'Gender Served': [],
  LinkedIn: '',
  'School Size': [],
  'School Website': '',
  'Student Residential Status': [],
  Title: '',
  Twitter: '',
  '[Created Date]': '05/11/2018 11:49:56 AM',
  '[Expiration Date]': '',
  '[Group]': [ 'Members' ],
  '[Last Modified Date]': '05/11/2018 11:49:56 AM',
  '[Member Status]': 'Active',
  '[Member Type]': 'Members',
  '[Username]': 'kk@yopmail.com' }

我想从对象中获取“名字”、“姓氏”和“用户名”。

任何想法？

解决方案

当属性值不能用点表示法访问时，使用括号表示法 - 只需将属性值放在括号内的字符串中：

var profile = { '[Profile ID]': 135675302,
  '[Name | Prefix]': '',
  '[Name | First]': 'KK',
  '[Name | Middle]': '',
  '[Name | Last]': 'Test',
  '[Contact Name]': 'KK Test',
  '[Email | Primary]': 'kk@yopmail.com',
  '[Email | Main]': 'kk@yopmail.com',
  '[Address | Primary | Line 1]': '',
  '[Address | Primary | Line 2]': '',
  '[Address | Primary | City]': '',
  '[Address | Primary | State]': '',
  '[Address | Primary | Zip]': '',
  '[Address | Primary | Country]': '',
  '[Address | Main | Line 1]': '',
  '[Address | Main | Line 2]': '',
  '[Address | Main | City]': '',
  '[Address | Main | State]': '',
  '[Address | Main | Zip]': '',
  '[Address | Main | Country]': '',
  '[Phone | Primary]': '',
  '[Organization]': '',
  '*Key Contact': '',
  Facebook: '',
  'Gender Served': [],
  LinkedIn: '',
  'School Size': [],
  'School Website': '',
  'Student Residential Status': [],
  Title: '',
  Twitter: '',
  '[Created Date]': '05/11/2018 11:49:56 AM',
  '[Expiration Date]': '',
  '[Group]': [ 'Members' ],
  '[Last Modified Date]': '05/11/2018 11:49:56 AM',
  '[Member Status]': 'Active',
  '[Member Type]': 'Members',
  '[Username]': 'kk@yopmail.com' };
  
  console.log(profile['[Name | First]']);
  console.log(profile['[Name | Last]']);
  console.log(profile['[Username]']);
