javascript - swal没有出现，但是数据传递了

Question

我试图在数据传递时显示 swal 成功消息。即使数据已传递，我也没有得到 swal，这显示在 chrome 控制台中

Uncaught ReferenceError: swal is not defined success @ CustomerLoyalty:40 (anonymous function) @ CustomerLoyalty:217

第 40 行:

    <script>
    function alerts() {
        swal({   title: "Are you sure you want to delete?",   text: "You will not be able to recover this record!",   type: "warning",   showCancelButton: true,   confirmButtonColor: "#DD6B55",   confirmButtonText: "Delete",   closeOnConfirm: false }, function(){   swal("Deleted!", "Employee Record has been deleted", "success"); });
    }

    function success() {
        swal("Warning!","Failed to record leave!", "success")
    }
</script>

上面是我的 swal 函数，当我单击控制台中的错误时，“swal(“警告!”，“无法记录离开!”，“成功”)”以红色下划线显示。 (见截图)

第 217 行:

 <form role="form" method="POST" action="http://localhost:8000/CustomerLoyalty">
                                                   <script type="text/javascript">success();</script>

谁能告诉我这里出了什么问题吗？我也将 swal 链接粘贴到我的标题中。 screenshot:

如果 swal 本身显示为未定义，则 swal 脚本根本无法加载。加载时检查网络选项卡，看看 swal js 是否已加载。
