如何使用 ejs 将一些 JS 代码包含到 Bootstrap 模式中？

Question

我有一个 ejs 页面，它使用一些数据，包括通过 <%= items[i].id %> 和按钮添加或删除项目的循环。一旦我将删除功能转移到引导模式（创建删除确认对话框），循环就会停止工作，只有第一个数组项被删除。我正在使用 Bootstrap 4.0 及其内置的 JQuery。如果在模态之外执行，删除工作正常。感谢您的任何提示！

<% for (let i=0; i<items.length; i++) { %>

<div class="card w-100 p-3">

  <form method="post" >

    <div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">

      <div class="card-header">

        <%= items[i].name  %>

      </div>

      <div class="card-body">

        <p class="card-text"> <%= items[i].desc  %> </p>

      </div>

      <button formaction="/project" type="submit" class="btn btn-outline-dark" name="editButton" value="<%= items[i].id  %>">Edit</button>

      <button type="button" class="btn btn-outline-danger" data-toggle="modal" data-target="#deleteModal">Delete</button>

    </div>

  </form>

</div>

<!-- Delete Modal -->

 <div class="modal fade" id="deleteModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

  <div class="modal-dialog" role="document">

    <div class="modal-content">

      <div class="modal-body">

        <form class="form-control" action="/delete" method="post">

          <p>Are you sure you want to delete <%= items[i].name  %> ? </p>

        <button type="submit" class="btn btn-outline-danger" name="deleteButton" value="<%= items[i].id  %>">Delete</button>

        <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>

        </form>

      </div>

    </div>

  </div>

</div> 

<% } %>

都<div class="model...具有相同的id属性。当您单击删除按钮时，只会打开第一个模式。添加<%= i %>为后缀id：<% for (let i=0; i<items.length; i++) { %>&nbsp; &nbsp; <div class="card w-100 p-3">&nbsp; &nbsp; &nbsp; &nbsp; <form method="post">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <button data-target="#deleteModal<%= i %>" type="button" class="btn btn-outline-danger" data-toggle="modal" >Delete</button>&nbsp; &nbsp; &nbsp; &nbsp; </form>&nbsp; &nbsp; </div>&nbsp; &nbsp; <!-- Delete Modal -->&nbsp; &nbsp; <div id="deleteModal<%= i %>" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">&nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; </div>&nbsp;<% } %>
