如何从百里香叶增加boostrap区域控制标签增量

Question

我需要使用列表计数增加区域控制boostrap taf.我的代码如下:

<th:block th:each="stateTitles, statesStatus: ${states}">
    <a data-toggle="collapse" id="stateCollapsed" class="collapsed" data-parent="#accordion" th:href="'#collapse' + ${statesStatus.index + 1}" 
        aria-expanded="true" aria-controls="'collapse' + ${statesStatus.index + 1}">
        <span id="state" th:text="${stateTitles}" /> 
        <span class="glyphicon glyphicon-menu-down"></span>
        <span class="glyphicon glyphicon-menu-up"></span>
    </a>
</th:block>

增量不适用于区域控制标记.提前致谢.

您需要使用th:attr以便使用Thymeleaf注入值,请在此处查看文档.

所以将代码更改为:

<a data-toggle="collapse" id="stateCollapsed" class="collapsed" data-parent="#accordion" th:href="'#collapse' + ${statesStatus.index + 1}" 
        aria-expanded="true" th:attr="aria-controls='collapse' + ${statesStatus.index + 1}">
