Question

我试图在传递数据时显示swal成功消息。即使数据通过我也没有得到swal，这显示在chrome控制台

中

未捕获的ReferenceError：未定义swal 成功@CustomerLoyalty：40 （匿名函数）@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>

以上是我的swal功能和＆＃34; swal（＆＃34;警告！＆＃34;，＆＃34;未能记录假！＆＃34;，＆＃34;成功＆＃34;）＆＃34;当我点击控制台中的错误时，下划线为红色。（见截图）

第217行：

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

谁能告诉我这里有什么问题？我已经在标题中粘贴了swal链接。screenshot:

Answer 1

如果swal本身显示为undefined，那么swal脚本dint会加载。加载时检查网络选项卡，看看是否加载了swal js。

Answer 2

SOLVEDIT

<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"); });
}

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

Swal没有显示，但数据已通过
