如何删除弹出通知消息中的<script> 编码？

Question

我正在使用 php 语言来做我的项目，我有一个关于如何删除弹出通知消息中的编码的问题？因为当我添加下面的代码时，它会显示通知弹出消息框：

希望有人能指导我如何删除它。谢谢。

如果您使用的是 Bootstrap，您应该使用Model Popup来显示您的 HTML 内容，而不是alert.<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"><script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><!-- Button trigger modal --><button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">&nbsp; Launch demo modal</button><!-- Modal --><div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">&nbsp; <div class="modal-dialog" role="document">&nbsp; &nbsp; <div class="modal-content">&nbsp; &nbsp; &nbsp; <div class="modal-header">&nbsp; &nbsp; &nbsp; &nbsp; <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>&nbsp; &nbsp; &nbsp; &nbsp; <button type="button" class="close" data-dismiss="modal" aria-label="Close">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <span aria-hidden="true">&times;</span>&nbsp; &nbsp; &nbsp; &nbsp; </button>&nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; <div class="modal-body">&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; <input type="text" id="branch_id3" /> <input type="text" id="merchant_type" />&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; <script>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$('#branch_id3').change(function(){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $('#merchant_type').val(0);&nbsp; &nbsp; &nbsp; &nbsp; })&nbsp; &nbsp; &nbsp;</script>&nbsp;&nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; <div class="modal-footer">&nbsp; &nbsp; &nbsp; &nbsp; <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>&nbsp; &nbsp; &nbsp; &nbsp; <button type="button" class="btn btn-primary">Save changes</button>&nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; </div>&nbsp; </div></div>
