上一篇文章我们已经知道如何利用Django弹出简单的消息提示框，文章链接：Django如何弹出简单的消息提示框
但是这样的界面有点丑，界面没有优化，下面介绍如何引入bootstrap的模态框作为自己的消息提示框，你会发现提示框比以前好看多了
1、引入bootstrap框架
最基本的框架，引入细节可以查看官网：https://v4.bootcss.com/docs/getting-started/introduction/
<!doctype html>
<html lang="en">
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.4.1/dist/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
<title>Hello, world!</title>
</head>
<body>
<h1>Hello, world!</h1>
<!-- Optional JavaScript -->
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script src="https://cdn.jsdelivr.net/npm/jquery@3.4.1/dist/jquery.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.4.1/dist/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>
</body>
</html>
2、加入模态框代码
代码如下：
<!-- Modal -->
<div class="modal fade" id="messageModal" tabindex="-1" role="dialog" aria-labelledby="messageModal" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="messageModal">提示信息</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" id="message-body">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">确认</button>
</div>
</div>
</div>
</div>
3、JS代码
{% if messages %}
<script>
$(document).ready(function(){
{% for msg in messages %}
// 把Django返回的消息内容更新为模态框的内容 通过id号查找
$("#messageModal").find("#message-body").html('{{ msg.message }}');
// 显示模态框
$("#messageModal").modal('show');
{% endfor %}
});
</script>
{% endif %}
4、测试
效果如下：
