Answer 1

在<script src="js/bootstrap.min.js"></script>

之前添加</body>

编辑：你还需要jQuery，在bootstrap.min.js之前添加

Answer 2

在bootstrap.min.js之前包含jquery

<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>

<!-- Latest compiled and minified JavaScript -->
<script src="js/bootstrap.min.js"></script>

Bootstrap需要运行jquery ...
