我的问题如下：
我在网站集根目录下有一个列表，代表名为“项目注册”的项目。该列表中的每个项目代表一个项目，我在其中存储项目名称、状态、URL 和一些其他属性。存储 URL 是因为每个项目在同一网站集下都有一个相应的 SharePoint 子网站，该网站集是通过在 Visual Studio 中创建的自定义事件接收器动态创建的。
每个项目子站点都有一个名为“成员”的列表，用于跟踪分配给该项目的人员。这是一项业务要求，此列表用于此问题范围之外的其他目的。
现在，我面临的挑战是，我需要在另一个名为“时间表”的列表的下拉列表中显示登录用户被分配到的项目。这是为了让用户能够输入在这些项目中花费的时间。此时间表列表不过是带有一些自定义字段的现成 SharePoint 日历列表。
下面是我正在使用的代码，但在检索成员列表时它一直给我以下错误。
未捕获的类型错误：无法调用未定义的方法“应用”
谁能指出我正确的方向？
我正在使用的代码位于我在母版页中正确引用的自定义 .js 文件中：
