sweetalert是一个漂亮的弹窗
中文网址：
http://mishengqiang.com/sweetalert/
它需要2个文件：sweetalert-dev.js和sweetalert.css
下载插件
怎么下载呢？直接从上面的网站扣下来，就可以了
修改index.html，引入2个资源
<script src="http://mishengqiang.com/sweetalert/js/sweetalert-dev.js"></script> <link rel="stylesheet" href="http://mishengqiang.com/sweetalert/css/sweetalert.css">
首页有一个删除还不错，直接贴过来即可！
index.html完整代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="http://mishengqiang.com/sweetalert/js/sweetalert-dev.js"></script>
<link rel="stylesheet" href="http://mishengqiang.com/sweetalert/css/sweetalert.css">
</head>
<body>
<button class="btn2">click</button>
<script>
$(".btn2").click(function () {
//删除示例代码
swal({
title: "确定删除吗？",
text: "你将无法恢复该虚拟文件！",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "确定删除！",
cancelButtonText: "取消删除！",
closeOnConfirm: false,
closeOnCancel: false
},
function (isConfirm) {
if (isConfirm) {
swal("删除！", "你的虚拟文件已经被删除。",
"success");
} else {
swal("取消！", "你的虚拟文件是安全的:)",
"error");
}
});
});
</script>
</body>
</html>
访问首页，点击click，效果如下：
表格删除一条记录
修改settings.py，开启csrf
MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ]
修改views.py，修改ajax_handle视图函数，返回一个json
def ajax_handle(request): if request.method == "POST": print(request.POST) #定义一个状态，假装删除成功了 response = {"state": True} return HttpResponse(json.dumps(response)) # 返回json else: return HttpResponse("非法请求,必须是POST")
修改index.html，写一个table，模拟删除操作
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script>

注意：在input里面定义的line_num是一个自定义属性，属性名，可以随便。
删除一条记录，效果如下：
注意：页面并没有刷新。那么第2条记录，是如何没有的呢？是用DOM操作，删除掉的！
