javascript - Angular 数据模型停止添加名称属性

Question

我想要一个当用户输入路线时被填充的日期字段。这是我正在使用的代码:

formular1.component.ts

constructor(
    private validateService: ValidateService,
    private flashMessage: FlashMessagesService,
    private authService: AuthService,
    private router: Router,
    private terminalService: TerminalService
  ) {
    this.todaysDate = new Date();
  }

formular1.component.html:

<input type="date" [ngModel]="todaysDate | date:'dd-MM-yyyy'" (ngModelChange)="todaysDate = $event" [value]="todaysDate | date:'yyyy-MM-dd'">

这工作正常，日期字段填充了正确的值，但我在控制台内遇到了一个大错误:

Error: If ngModel is used within a form tag, either the name attribute must be set or the form
      control must be defined as 'standalone' in ngModelOptions.

      Example 1: <input [(ngModel)]="person.firstName" name="first">
      Example 2: <input [(ngModel)]="person.firstName" [ngModelOptions]="{standalone: true}">

听起来很简单...但是当我添加 name="test" 时属性 dateField 不再工作并且未填充日期值 - 为什么？

也许有人也可以告诉我，如何在德国获得正确的时间(夏季/冬季)，从我得到的日期起实际上还有+1小时New Date();

问题出在日期格式化管道上

  <input type="date" name="todayDate" id="todayDate" [ngModel]="todaysDate | date:'yyyy-MM-dd'" (ngModelChange)="todaysDate = $event" [value]="todaysDate | date:'yyyy-MM-dd'">

如果要转换为dd-mm-yyyy格式check this one
