DatePicker无法在bootstrap 4上运行

时间：2017-12-07 05:35:02

标签： jquery html datepicker bootstrap-4

我想在我的项目中使用datepicker。这是我第一次使用bootstrap。问题是当我点击日期表单时没有显示datepicker。我已经尝试在标签内部和内部替换CDN url位置但仍然没有工作。我不知道我犯了什么错误，希望你们能帮我解决这个问题谢谢你。

您正在导入jQuery两次（1.12.4和3.1.1）。删除v1.12.4并将jquery-ui.js移到底部（在jQuery 3.1.1之后）。

您的代码运行良好，但您需要更改格式。底层来源存在问题。

我已经检查了您的上述代码另外两个Javascripts或包含在您的项目中，从代码中删除这些javascript

我认为你应该添加'popper.js'文件，因为Bootstrap 4弹出元素依赖于popperjs。

Popper.js
