javascript - 将 id 解析为 Bootstrap 模式

Question

我有一个包含一堆字符串的 Bootstrap 模式。我还有一串卡片，每张卡片都有不同的“id”。当我打开模态时，我希望 id 显示在模态内(稍后我将使用它来获取更多信息，例如名称、描述和截止日期)。

这是我的 JSON 对象循环:

<div class="card-list-body">
            {% for assignment in förseningar %}
                <div class="card card-kanban" data-toggle="modal" data-target="#task-modal" id="{{assignment.id}}">

                   <script>
                     $('#task-modal').on('show.bs.modal', function(event) {
                     var Id = $(event.relatedTarget).data('id');
                     console.log("aaa")
                     $(event.currentTarget).find('input[name="modal-title"]').val(Id);
                    });
                   </script>


                  <div class="card-body">
                    <div class="dropdown card-options">
                      <button class="btn-options" type="button" id="kanban-dropdown-button-16" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                        <i class="material-icons">more_vert</i>
                      </button>
                      <div class="dropdown-menu dropdown-menu-right">
                        <a class="dropdown-item" href="#">Edit</a>
                        <a class="dropdown-item text-danger" href="#">Archive Card</a>
                      </div>
                    </div>

                    <div class="card-title" style="white-space: initial; ">
                        <a href="#" data-toggle="modal" data-target="#task-modal">

这是模态的一部分:

javascript:

<script>
                 $('#task-modal').on('show.bs.modal', function(event) {
                 var Id = $(event.relatedTarget).data('id');
                 console.log("aaa")
                 $(event.currentTarget).find('input[name="modal-title"]').val(Id);
                });
               </script>

正如我所说。我想要卡片的详细信息页面。所以当我按下卡片时，我会弹出一个窗口。我希望该弹出窗口包含更详细的卡片页面。我不知道如何将数据放入弹出模式(任务模式)我认为这很接近，但如果有人能提供帮助，我们将不胜感激!

Answer 1

三个问题:

• 您的 javascript 在 for 循环内 ( {% for assignment in förseningar %} )，它应该在外面。否则重复 x 次。
• var Id = $(event.relatedTarget).data('id')意味着触发模式的按钮有一个 data-id属性。但是你的没有，它有一个 id属性。所以要么设置data-id="{{ assignment.id }}"在<div class="card card-kanban" ...>或更改为 var Id = $(event.relatedTarget).attr('id') .
• $(event.currentTarget).find('input[name="modal-title"]')表示您正在寻找 <input name="modal-title">模态中的元素，但我在任何地方都看不到它。也许它被切断了，在这种情况下没问题。但是如果你想改变 modal-title div，那么选择器应该是:$(this).find('.modal-title') .

注意:我使用 $(this)而不是 $(event.currentTarget) .作为 currentTarget 应该没有任何区别是模态，所以是 this .
