我正在使用sorttable.js对从我们的Mysql数据库中提取的表进行排序。数据库有我们提供的课程的开始和结束日期。排序工作很好，但我只注意到，按日期排序时，即使年份较早（即2015年和2016年），总是会在10-12月结束，以便例如10/01/15显示在底部之后16年1月1日。我知道它必须是简单的调整，但我一直无法弄清楚在哪里或如何。我不是很熟练的JavaScript，可以使用一点点的帮助。有人能告诉我我做错了什么吗？使用sorttable.js进行日期排序，按年份然后按月然后按日期排序

日期格式如何显示，如下所示：10/01/1 5？ – Tarek
是的。对不起忙于其他事情。 – Inky1231
