Angular4_Checkbox多选框选中事件,与其他组件交互

<input type="checkbox" [rtSelectionCheckboxFor]="hu" [(selected)]="hu.selected"  (change)="onChecked($event); setRtList(list);"/> 

用的事change事件监听的

 onChecked($event: any) {
    this.changeStatus.emit(true);
  }

 changeStatus(agreed: boolean) {
        let isEdit = true;
        let isReturn = true;
        let isCombine = true;

        const selectedRows = this.gridComponent.getSelectedRows();
        if (selectedRows && selectedRows.length >= 1) {
          isEdit = false; isReturn = false; isCombine = true;
          if (selectedRows && selectedRows.length === 2) {
            isEdit = true; isReturn = true;
            isCombine = false;
          } if (selectedRows && selectedRows.length > 2) {
            isEdit = true; isReturn = false;
            isCombine = true;
          }
        }
        this.footerComponent.setHuButtonStatus(isEdit,isReturn,isCombine);
      }
