有条件地关闭Thymeleaf中的标签 [英] Conditionally closing tag in Thymeleaf

问题描述

我需要有条件地关闭 Thymeleaf 模板中的标签。说，在迭代某些元素期间，我必须将其中的一些元素包装为单个< div> ：

I need to conditionally close tag in my Thymeleaf template. Say, during iterating some collection of elements I have to wrap series of some of them into single <div>:

<div>...element1, element2, element3...</div>
<div>...element4...</div>
<div>...element5, element6...</div>

如果存在某种条件的标签关闭方式，则可以将其存档。但是我显然不能写< / div th：if = ...> 。如果是 jsp ，我可以轻松地写成这样：

This could be archived if some way of conditionally tag closing would exist. But I can't obviously write </div th:if="...">. If it would be jsp I could easily write something like:

<%if (condition) {%></div><%}%>

任何想法如何解决此问题？

Any ideas how to solve this issue?

编辑确切地说，我的元素不仅仅是字符串，它们是复杂的内部html块。

EDIT To be precise, my elements aren't just strings, they are complex inner html blocks.

推荐答案

我找到了解决方法。应该包装为单个< div> 的一系列块应在模型中表示为单独的列表。说，我有 Element 类，它描述了我的 element 块。因此，我的模型应为：

I've found the workaround. Series of blocks which should be wrapped into single <div> should be represented as separated lists inside model. Say, it I have Element class which describes my element block. So, my model should be like:

List< Element> elementGroups

，我必须为其创建双循环：

and I have to create double loop for it:

<div th:each="group : ${elementGroups}">
    <th:block th:each="element : ${group}">
       ...
    </th:block>
</div>
