Bootstrap Datetimepicker库的头文件

在使用Bootstrap Datetimepicker库时，需要引入以下头文件：

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1 Cha /C2mN9teEULT0M0rjfooEIFktBx" crossorigin="anonymous">

<!-- Datetimepicker CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap-datetimepicker@4.17.47/build/css/bootstrap-datetimepicker.min.css" integrity="sha384-uL9g6D0qJLj1aY3UG1sJFy0kQmL6gTgQq+4gNkDzZfXvjqZ+R8UzL2hmQJ5QwVqE" crossorigin="anonymous">

<!-- jQuery -->
<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

<!-- Moment.js -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js" integrity="sha384-xpB1Sti5+I0h6wIH3xF5s8i/4HCpU4UFSq6L4JUkByBbjSsTqjJXK3g5LGyXaWZ5" crossorigin="anonymous"></script>

<!-- Datetimepicker JS -->
<script src="https://cdn.jsdelivr.net/npm/bootstrap-datetimepicker@4.17.47/build/js/bootstrap-datetimepicker.min.js" integrity="sha384-1L5ksNi6Gyv4v8e6fZ2I1KO2XuQ3n6i4qdhkZb3gJy/0BW5KtjvN5onl+8b8DcS8" crossorigin="anonymous"></script>

<!-- Bootstrap JS -->
<script src="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js" integrity="sha384-7EuT6aDlQwZlQQwq5/Ks6wfvZKkUntG0OmWwo5pXJlIB+IkyRxg4tqydhj8LvO9a" crossorigin="anonymous"></script>

以上是Bootstrap Datetimepicker库的必要头文件。需要注意的是，除了jQuery和Moment.js是必须的外，其他库的版本号可能会不同，需要根据实际情况进行修改。
