8.BootStrap依赖


BootStrap依赖JavaScript的类库,jQuery。


  • 下载
https://jquery.com/


在页面上应用BootStrap的javaScript类库


Step1:引入

<script src="static/js/jquery-3.6.3.min.js"></script>
<script src="plugins/bootstrap-3.4.1-dist/js/bootstrap.min.js"></script>


Step2:测试


这里使用一个模态框测试

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="plugins/bootstrap-3.4.1-dist/css/bootstrap.css">
    <link rel="">
</head>
<body>
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
<script src="static/js/jquery-3.6.3.min.js"></script>
<script src="plugins/bootstrap-3.4.1-dist/js/bootstrap.min.js"></script>
</body>
</html>
