javascript - for循环模式不传递信息

问题描述

这是非常基本的，但不起作用，我没有想法......我想它在我的设置中

它是引导程序的基本模式

它应该在发件人中显示@mod，但它看起来很干净......所以我不确定发生了什么以及如何使其工作。

我使用mozilla firefox进行开发，是使用python和烧瓶的应用程序，但问题似乎出在后台 javascript 中？

基本上我有一个 for 循环

{% extends 'base.html' %}
{% block content %}
{% include 'navbar.html' %}

            {% for total in totales %}
        <tr>
            <td>{{ total.id_control }}</td>
            <td>{{ total.fecha }}</td>       
            <td><button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button></td>
        </tr>
        {% endfor %}

从这里它应该给我打开一个模态

<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
  <div class="modal-content">
    <div class="modal-header">
      <h5 class="modal-title" id="exampleModalLabel">New message</h5>
      <button type="button" class="close" data-dismiss="modal" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
    </div>
    <div class="modal-body">
      <form>
        <div class="form-group">
          <label for="recipient-name" class="col-form-label">Recipient:</label>
          <input type="text" class="form-control" id="recipient-name">
        </div>
        <div class="form-group">
          <label for="message-text" class="col-form-label">Message:</label>
          <textarea class="form-control" id="message-text"></textarea>
        </div>
      </form>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Send message</button>
    </div>
  </div>
</div>

使用 javascript 传递信息

    <script type='text/javascript'>
$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})
    </script>
{% endblock %}

base.html 中的设置是

    <!doctype html>
<html lang="en">
  <head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

    <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="{{ url_for('static', filename='css/bootstrap.min.css') }}">
 
    <title>{{ title }}</title>
  
  </head>
  <body>
    {% block content %}
    {% endblock content %}


    <!-- Optional JavaScript -->
    <!-- jQuery first, then Popper.js, then Bootstrap JS -->
    <script src="{{ url_for('static', filename='js/jquery-3.3.1.slim.min.js') }}"></script>
    <script src="{{ url_for('static', filename='js/popper.min.js') }}"></script>
    <script src="{{ url_for('static', filename='js/bootstrap.min.js') }}"></script>
  </body>
</html>
