解释->有两个屏幕，我想将复选框值存储为ISACTIVE的MAT TABLE中的yes或no！当我选择复选框并在垫子表项中单击保存按钮后，应输入YES。当我取消选中复选框并在垫子表项中单击保存按钮后，应输入为。 stackblitz在这里链接-> https://stackblitz.com/edit/angular-gbf9kz-uqyihm?file=app%2Ftable-basic-example.html

Answer 1

因此，在这里，我为您添加了一个表格，一旦正确填写即可注册。

  newOffersForm: FormGroup; //Formulaire
  @ViewChild('formDirective') formDirective: FormGroupDirective; //Erreur formulaire

  ngOnInit() {
    this.newOffersForm = new FormGroup({
      name: new FormControl('', [Validators.required, Validators.minLength(4)]),
      code: new FormControl('', [Validators.required]),
      isActive: new FormControl(false)
   });
  }

表单的所有输入都会创建一个“ dataObject”对象，该对象将被推送到表的数据列表中。

  dataObject: data;
  offersColumnRowData: data[] = [];

export interface data {
  name: string;
  code: string;
  isActive: boolean;
}

在表单中，“ isActive”的值默认为FALSE，如果选中此复选框，则为TRUE。这是表中处理“是/否”的显示。

<ng-container matColumnDef="ISACTIVE">
  <mat-header-cell *matHeaderCellDef> ISACTIVE </mat-header-cell>
  <mat-cell *matCellDef="let element">{{element.isActive? 'YES':'NO'}}</mat-cell>
</ng-container>
