datepicker not defined - jQuery

datepicker not defined - jQuery

本文关键字：jQuery defined not datepicker      更新时间：2023-09-26

我创建了一个django应用程序。在我的应用程序中，我有一个注册从中有一个日期字段。为此，我使用jQuery日期拾取器。它以前工作得很好，但今天当我开始我的应用程序不工作的一些未知的原因。我不能理解为什么它不工作在我的代码，但工作得很好，当我单独在一个新的html脚本。它现在显示的错误是datepicker不是一个函数。谁来调查一下。我将把我的html代码粘贴到这里。

我不知道这是否与你的问题有关，但你在你发布的代码片段中有一些无效的HTML。我首先要确保你所有的标签都是平衡的，你有一个第二形式的标签，它不会被关闭。此外，您的表中还有几个未关闭的粗体标记

我修好了。这是我的一个小疏忽。js文件在从{% facebook_connect_script %}扩展的另一个页面中引用。非常感谢大家的帮助
