此代码应该：找到匹配所选按钮的日期（例如，星期一）的对象课程，然后;根据开始时间对列表进行排序。由于对象中信息的性质，我将它们转换为军事等值用于比较目的。一旦完成后，它应该最终显示具有在声明中指定的信息的已排序课程列表。JSON/JavaScript功能/实现
但是，当我选择一个按钮时，什么也没有发生。没有显示任何内容，编译时也不会在代码中发现任何错误。

什么问题：由于计数器LD从未运行（始终为0）正在对名单（永远不为0）
这里是为您小提琴的大小测试？有错误吗？如果是这样，那么错误信息是什么？代码是否不像您期望的那样行事？如果是这样，会发生什么？你期望会发生什么？ – Asaph
对不起，不包含该信息。在理想情况下，代码应该：从JSON对象中找到匹配所选按钮的一天（例如，星期一）的课程，然后;根据开始时间对列表进行排序。由于JSON对象中信息的性质，我将它们转换为其军事等价物用于比较目的。一旦完成后，它应该最终显示具有在声明中指定的信息的已排序课程列表。我一直在尝试使用准备运行onclick函数的准系统HTML页面上的按钮来测试它，但它似乎不起作用。 –
