我在页面上有一个链接可以打开和关闭搜索表单。例如，您搜索Spring术语类，然后要搜索新术语并单击“开始新搜索”。链接工作得很好，切换就好......除了切换自动再次关闭。我无法弄清楚为什么会发生这种情况，我已经搜索了堆栈溢出网站，并且没有一个解决方案似乎有用（或者我可能仍然做错了什么）我们将非常感谢您给予我的任何帮助。 这是调用函数的部分

该选择器的单击处理程序提交表单。提交表单将根据action网址代码中设置的条件重新加载新网页，除非该表单是通过ajax提交的。
加载新页面时没有保存页面状态。
因此，您基本上看到页面将自身重置为新版本

我发现了我的问题，有一个无关的脚本副本
$(".course-schedule-wrapper .toggle-search a").click(function(e){
e.preventDefault();
$("#course-schedule-search").slideToggle();
});
在其他一个提供给页面的文件中。删除该副本，现在它工作得很好！为了记录，这并不像这个“时间表”页面那么简单，开发人员创建了6个不同的文件来提供这一页！
