如何在 Spring Boot Thymeleaf 列表中使用 Bootstrap 模式? [英] How to use Bootstrap Modals with Spring Boot Thymeleaf List?

问题描述

我列出了我的用户.它完美运行，每个用户都有自己的 Bootstrap 卡.但是当我点击更多"时触发模态，每更多"按钮给出相同的模态，这是用户 #1 的弹出窗口.所以无论我对哪个用户的数据感兴趣，它总是显示相同的模态.我希望它能够正常工作，这样每当我点击更多按钮时，窗口就会弹出该用户的数据.

 <div th:each="user : ${listUsers}"类=卡mb-3"><div 类=行 g-0"><!-- <div class="col-md-3"><img src="/images/noimage2.png"alt="..."></div>--><div 类=col-md-12"><div 类=卡体"><h3 class=卡片标题"th:text="${user.name}">名称</h3><!-- 按钮触发模式--><按钮类型=按钮"class="btn btn-secondary btn-sm"data-bs-toggle=模态"；data-bs-target="#exampleModal"><i class="fas fa-address-card"></i>更多的</按钮><!-- 模态--><div 类=模态淡入淡出";id="exampleModal";tabindex="-1";aria-labelledby=exampleModalLabel";aria-hidden="true">

解决方案

你所有的按钮都指向 #exampleModal -- 你可以在这里看到:data-bs-target="#exampleModal".如果你想让按钮工作，你需要给你的每个模态一个唯一的 id，然后用正确的按钮定位正确的模态.所以...

1. 添加 状态变量 进入你的循环.

2. 使用 ${status.index} 变量为您的目标创建唯一 id:

    <button type="button";class="btn btn-secondary btn-sm"data-bs-toggle=模态"；th:data-bs-target="|#userModal${status.index}|"><i class="fas fa-address-card"></i>更多的</按钮>

3. 使用 ${status.index} 变量为您的模式创建一个唯一的 id:

I list out my users. It works perfectly, every user has their own Bootstrap card. But when I click on "more" to trigger the Modal, every "more" button gives the same Modal, which is the pop-up window for User #1. So no matter which user's data interests me, it always shows the same Modal. I want it to work properly, so that whenever I click on the more button the window pops up with that user's data.

    <div th:each="user : ${listUsers}" class="card mb-3">
                <div class="row g-0">
                    <!--  <div class="col-md-3">
                        <img src="/images/noimage2.png" alt="...">
                    </div>-->
                    <div class="col-md-12">
                        <div class="card-body">
                            <h3 class="card-title"
                                th:text="${user.name}">Name</h3>

                            <!-- Button trigger modal -->
                            <button type="button" class="btn btn-secondary btn-sm"
                                data-bs-toggle="modal" data-bs-target="#exampleModal">
                                <i class="fas fa-address-card"></i> More
                            </button>

                            <!-- Modal -->
                            <div class="modal fade" id="exampleModal" tabindex="-1"
                                aria-labelledby="exampleModalLabel" aria-hidden="true">
                                <div
                                    class="modal-dialog modal-dialog-scrollable modal-lg modal-dialog-centered">
                                    <div class="modal-content">
                                        <div class="modal-header">
                                            <h5 class="modal-title" id="exampleModalLabel"
                                                th:text="${user.name}">Modal title</h5>
                                            <button type="button" class="btn-close"
                                                data-bs-dismiss="modal" aria-label="Close"></button>
                                        </div>
                                        <div class="modal-body">

                                            <span class="d-inline"
                                                th:text="${user.address}"></span> | <span
                                                th:text="${user.phoneNumber}"></span> | <span
                                                th:text="${user.email}">email</span>
                                        </div>

                                        <p class="card-body"
                                            th:text="${user.description}"></p>
                                    </div>
                                    <div class="modal-footer"></div>

                                </div>
                            </div>
                        </div>
                    </div>
                </div>
            </div>
            <p>
        </div>

解决方案

All of your buttons are targetting #exampleModal -- you can see here:data-bs-target="#exampleModal". If you want the buttons to work, you need to give each of your modals a unique id and then target the correct modal with the correct button. So...

1. Add the status variable onto your loop.

   <div th:each="user, status : ${listUsers}" class="card mb-3">
   

2. Use the ${status.index} variable to create a unique id for your target:

    <button type="button" class="btn btn-secondary btn-sm"
            data-bs-toggle="modal" th:data-bs-target="|#userModal${status.index}|">
      <i class="fas fa-address-card"></i> More
    </button>
   

3. Use the ${status.index} variable to create a unique id for your modal:

    <div class="modal fade" th:id="|#userModal${status.index}|" tabindex="-1"
      aria-labelledby="exampleModalLabel" aria-hidden="true">
