Question

我在组件中使用一种反应形式，并且对我的开发环境工作良好。但是在生产环境中，我会遇到

的FormGroup元素错误

ClientApp \ app \ panel \ applyLeave \ applyLeave.component.html（86,36）中的错误：属性'reportingPerson'在'ApplyLeaveComponent'类型上不存在。 ClientApp \ app \ panel \ applyLeave \ applyLeave.component.html（99,36）：：属性'notifyPerson'在'ApplyLeaveComponent'类型上不存在。 ClientApp \ app \ panel \ applyLeave \ applyLeave.component.html（114,86）：：类型'ApplyLeaveComponent'上不存在属性'loading'。 ClientApp \ app \ panel \ applyLeave \ applyLeave.component.html（86,36）：：属性'reportingPerson'在'ApplyLeaveComponent'类型上不存在。 ClientApp \ app \ panel \ applyLeave \ applyLeave.component.html（99,36）：：属性'notifyPerson'在'ApplyLeaveComponent'类型上不存在。

Component.ts文件：-

export class ApplyLeaveComponent {
  leaveForm: FormGroup;

  ngOnInit() {
    this.leaveForm = this.fb.group({
      leaveType: ['', Validators.required],
      leaveFromDate: ['', Validators.required],
      leaveToDate: ['', Validators.required],
      leaveReason: ['', Validators.required],
      reportingPerson: ['', Validators.required],
      notifyPerson: ['', Validators.required]
    })
  }
}

component.html：-

    <form [formGroup]="leaveForm" class="row" 
    (ngSubmit)="applyLeave(leaveForm)">

  <div class="form-group col-4">

                               [(ngModel)]="notifyPerson"
                               formControlName="notifyPerson"
                               required>

   </div>
  <div class="form-group col-5">
    <label for="" class="col-form-label">Reason</label>
    <div class="">
      <textarea class="form-control form-control-sm" 
      formControlName="leaveReason" required></textarea>
    </div>
    <div *ngIf="submitted && f.leaveReason.invalid"> <div 
      *ngIf="f.leaveReason.errors.required" style="color:red ; font- 
      size:13px">* <span>Required</span></div></div>
    </div>
  <div class="col-3">
    <button type="submit" class="btn btn-primary" name="submit" 
    id="leavebutton" [disabled]="loading">Apply</button>
  </div>
</form>

我尝试将我的表单组的类型用作leaveForm:any=FormGroup;，但这不能解决问题

由于已绑定属性notifyPerson和其他提及的属性，例如[(ngModel)]="notifyPerson"，因此需要在ts中声明它。

赞：

notifyPerson:string
reportingPerson:string

同样，您需要像这样声明属性loading：

loading:boolean

注意：避免以反应形式使用[(ngModel)]

在生产构建期间，类型Component上的属性不存在
