使用Bootstrap和Thymeleaf从列表中动态创建选项卡

thymeleaf twitter-bootstrap

假设我有一个对象列表“Bar”,每个Bar有两个属性“title”和“content”: 如何为列表中的每个栏动态创建带有调色板的选项卡?

这里是犯罪代码:

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
  <head>
    <title>Bar's tab</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous" />

  </head>
  <body>
   <div class="container">

      <ul class="nav nav-tabs" >
        <div th:each="bar: ${bar_list}">
          <li class="nav-item">
            <a class="nav-link" th:href="@{'#'+ ${bar.title}}" data-toggle="tab"><label th:text="${bar.title}">bar title</label></a>
          </li>
        </div>
      </ul>

      <div class="tab-content" >
        <div th:each="bar : ${bar_list}">
              <div class="tab-pane fade active" th:id="${bar.title}">
                  <p th:text = "${bar.content}">bar content</p> 
              </div>          
        </div>
      </div> 

    </div>
  </body>
</html>

请删除多余的、封闭的div(那些包含 th:each 属性)。此外,只应显示一个选项卡窗格 active 一开始,并不是所有人。你应该在里面添加一些条件 th:classappend 为了实现这一点。

<body>

<div class="container">
    <ul class="nav nav-tabs" >
        <li class="nav-item" th:each="bar, barStat: ${bar_list}">
            <a class="nav-link" th:classappend="${barStat.first} ? 'active'" th:href="@{'#'+ ${bar.title}}" data-toggle="tab"><label th:text="${bar.title}">bar title</label></a>
        </li>
    </ul>

    <div class="tab-content" >
        <div class="tab-pane fade" th:classappend="${barStat.first} ? 'show active'" th:id="${bar.title}" th:each="bar, barStat : ${bar_list}">
            <p th:text = "${bar.content}">bar content</p> 
        </div>
    </div> 
</div>
