Question

我对我的应用程序的相同方面有两个问题，抽象视图是这样的：

该应用程序允许用户查看不同的视频剪辑。在后端/管理部分，管理员可以跟踪任何特定剪辑组的视图。例如，管理员可以选择Universal Studios，选择date range: Beginning Date: 2015-01-1, End Date: 2016-01-1并点击filter，然后查看Universal在此范围内收到的总观看次数。

问题是，对于其中一个， datepicker 不再有效，所以当我点击日期字段时，没有显示日历，我手动必须输入日期。对于两个人，我只能在最远的地方获得结果：2015-10-18和2016-02-18。当我输入2015-09-18或之前的任何内容时，它都不会生成结果。
