我试过很多类似的问题。还是找不到。请帮我。我知道这似乎是重复的。但不知何故不是。这是因为我为下拉列表添加了各种 ID。 （我猜）。请帮忙。谢谢你。
尝试使用 jQuery 而不是 $
所以
jQuery('document').ready(function () {
jQuery("#datepicker1,#datepicker2").datepicker({
minDate: 0,
beforeShowDay: $.datepicker.noWeekends,
dateFormat: "dd-mm-yy"
});});
两天后我终于弄明白了。我的 jsp 页面在主页中加载，因此主页也在项目中调用来自 jquery 的页面。我删除了 jsp 的 cdn 并让主页调用 jquery 中的那些。非常感谢大家的帮助。
Ps：我觉得自己好傻。 :D
我正在尝试使用 jquery-ui 日历做一些事情。加载页面时，它会给我这些错误。
