<ng-template ngFor [ngForOf]="checklist" let-item let-i="index">
            <div class="ui checkbox">
              <input type="checkbox" name="status" [checked]="item.isChecked">
              <label for="wait-loan-id" class="Settlement">{{item.name}}<span class="black">({{item.cnt}})</span></label>
            </div>
          </ng-template>
the effect of the page is as follows:
The code for  
 ts looks like this: 
getCheckList(): void {
    let statusList: any = [
      { name: "", value: 0, cnt: 0 },
      { name: "", value: 2, cnt: 0 }
    ];
    statusList.map((item) => {
      return item.isChecked = true;
    });
    this.checklist = statusList;
  }
chooseStatuses(event, index): void {
    let { value, checked } = event.target;
    this.toggleItemStatuses(checked, value, index);
  }
 subscript status 
 when I send a request, I need to determine whether the check of the status is to select all or single. If I select all, I need 
 org/apply?status=0&status=2 to request from the backend. If I choose one, I will monitor the change of the input value. But I will not, and the logic of judging the status of the single selection and selecting or canceling the current state is not very clear. Ask for help from the boss!
