  <!--          匯出excel-->
              <div class="col-sm-1" >
                <button   style="" type="button" class="btn btn-warning q7" data-toggle="modal" data-target="" (click)="exportExcel()"

前端ts

  exportExcel() {
    //使用window.location.href連結跳轉
    window.location.href = url() + '/dhTask/myExportExcel?time='+this.time+'&searchMsg='+this.searchMsg;
  }
