模态框关闭时表单重置JS代码单页有效另一页失效问题排查

Hey there! Let's figure out why your #addProjectModal isn't clearing the form when it closes, even though the exact same logic works flawlessly for #addadminprofile.

核心原因：HTML结构损坏 #

Looking at the HTML snippet you shared, the #addProjectModal has unclosed nested elements—that's the root of your problem! Let me highlight the issue:

<!-- Modal -->
<div class="modal fade" id="addProjectModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-xl" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Ajouter un projet</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <form action="suiviProjet.php" method="POST">
<!-- 这里直接开始了另一个模态框，完全没闭合form、modal-content、modal-dialog、modal的div标签！ -->

When HTML tags aren't properly closed, browsers can't parse the DOM structure correctly. This means jQuery can't reliably find the #addProjectModal element or its nested form, so your event listener never gets triggered.

修复方案：补全闭合标签 #

You need to close all unclosed elements for #addProjectModal before starting the next modal. Here's the corrected, complete HTML for #addProjectModal:

<!-- Modal -->
<div class="modal fade" id="addProjectModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-xl" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Ajouter un projet</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <form action="suiviProjet.php" method="POST">
        <!-- 在这里放置你的表单输入字段 -->
      </form> <!-- 闭合form标签 -->
      <div class="modal-footer">
        <!-- 如果有底部按钮，放在这里 -->
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Fermer</button>
        <button type="submit" class="btn btn-primary">Enregistrer</button>
      </div>
    </div> <!-- 闭合modal-content标签 -->
  </div> <!-- 闭合modal-dialog标签 -->
</div> <!-- 闭合modal标签 -->

额外优化建议 #

1. Wrap your JavaScript code in a $(document).ready() block to ensure it runs only after the DOM is fully loaded:

   $(document).ready(function() {
     $('#addProjectModal').on('hidden.bs.modal', function () { 
       $('#addProjectModal form')[0].reset(); 
     });
     $('#addadminprofile').on('hidden.bs.modal', function () { 
       $('#addadminprofile form')[0].reset(); 
     });
   });
   

2. Double-check that there are no duplicate id values on the page—each modal must have a unique identifier.

Once you fix the broken HTML structure, your existing JavaScript will work perfectly for both modals!
