atom 没有定义变量，会走不下去，也不会报错，

showPlatformView(){
      this.prdId = this.selectedIds.map(item => item.id).toString();
      if(!prdId || prdId.split(',').length > 1){
          this.$Modal.warning({
              title: '系统提示',
              content: '<p style="font-size:16px">请选择一行！</p>'
          });
          return;
      }
      this.platformPage = true;
}
