如何在 Angular 2 App 中包含时刻时区

问题描述

我意识到，这个问题重复了，但上一次没有提供恰当的答案时刻包已经安装

I realize, this question is repeated but previous once does not provide apt answermoment package was already installed

1.安装包

npm install moment-timezone --save

在node_modules目录内
|
|--时刻
|--moment-timezone

Inside node_modules directory
|
|--moment
|--moment-timezone

存在的目录

2.Index.html 包含脚本

<script src="node_modules/moment-timezone/moment-timezone.js"></script>

System.config.js

  var map = {
    'moment':             'node_modules/moment',
    'momentzone':         'node_modules/moment-timezone'
  };
  var packages = {
    'moment':             { defaultExtension: 'js' },
    'momentzone':         { defaultExtension: 'js' }
  };

3.Inside component.ts 文件

import * as moment from 'moment/moment';

export class TimeComponent implements OnInit{
   ngOninit(){
         console.log(moment("2014-06-01T12:00:00Z").tz('America/Los_Angeles').format('ha z'));

   }
}

应该导入什么来防止出错时刻"类型不存在属性 tz

What should be imported to prevent errorProperty tz does not exist on type 'Moment'

推荐答案

这可能会有所帮助.

为 angular-cli 或 npm install 运行以下命令.

Run Following command for angular-cli or npm install.

sudo npm install moment moment-timezone --save
npm install @types/moment @types/moment-timezone --save-dev

对于 npm systemjs.config.js

for npm systemjs.config.js

   map: {
        'moment': 'npm:moment',
        'moment-timezone': 'npm:moment-timezone/builds'
      }
packages: {
      'moment': {
          main: './moment.js',
          defaultExtension: 'js'
       },
      'moment-timezone': {
        main: './moment-timezone-with-data-2010-2020.min.js',
        defaultExtension: 'js'
      }
}

你想在 .ts 文件中使用时区的地方

where ever you want to use time-zone in .ts file

import * as moment from 'moment-timezone';

@Component({
  selector: 'my-app',
  template: `<h1>Hello {{name}}</h1>`,
})

export class AppComponent {
  name = 'Angular';
  jun = moment();// creating obj.
  constructor() {
    this.jun.tz('America/Los_Angeles').format('hh : mm : ss a z');
    console.log(this.jun.tz('America/Los_Angeles').format('hh : mm : ss a z'));
    console.log(moment.tz.names()); // for all time zone.
  }
