在angular4中具有[(ngModel)]的多个复选框中选择特定复选框时选中的所有复选框

selectedCheckboxes: string[] = [];

<input type="checkbox" [(ngModel)]="selectedCheckboxes" (change)="updateSelectedCheckboxes('checkbox1')" /> Checkbox 1
<input type="checkbox" [(ngModel)]="selectedCheckboxes" (change)="updateSelectedCheckboxes('checkbox2')" /> Checkbox 2
<input type="checkbox" [(ngModel)]="selectedCheckboxes" (change)="updateSelectedCheckboxes('checkbox3')" /> Checkbox 3

updateSelectedCheckboxes(value: string) {
  if (this.selectedCheckboxes.includes(value)) {
    // 如果已经选中，则从数组中移除
    this.selectedCheckboxes = this.selectedCheckboxes.filter(item => item !== value);
  } else {
    // 如果未选中，则添加到数组中
    this.selectedCheckboxes.push(value);
  }
}
