我创建了一个 Django 应用程序。在我的应用程序中，我有一个注册，其中有一个日期字段。为此，我使用 jQuery datepicker。它以前工作正常，但今天当我开始我的应用程序时，由于某种未知的原因它无法工作。我无法理解为什么它在我的代码中不起作用，但是当我在新的 html 中单独给出该脚本时工作正常。现在显示的错误是 datepicker 不是函数。有人可以研究一下吗？我将在此处粘贴我的 html 代码。

我不知道这是否与您的问题有关，但您发布的代码片段中有一些无效的 HTML。我首先要确保所有标签都是平衡的，你有一个不会关闭的第二种表单标签。此外，您的表格中有几个粗体标签也未关闭。
