对于 Thymeleaf 中的每个运算符 [英] For each operator in Thymeleaf

问题描述

我在 Thymeleaf 模板中找不到用于构建简单 for-each-loop 的语法.我对 th:each="" 属性不满意，因为它复制了它所在的标签.

I can not find syntax for building simple for-each-loop in Thymeleaf template. I'm not satisfied with just th:each="" attribute, because it copies tag in which it's located.

我正在寻找的是这样的:

What I'm looking for is something like:

<th:foreach th:each="...">
...block to be repeated...
</th>

或 .有什么类似的吗?

what is analogue of <c:forEach items="..." var="..."> or <t:loop source="..." value="..."> in Tapestry. Is anything similar for that?

推荐答案

使用 th:block 如 Thymeleaf 指南中所述

Use th:block as stated in the Thymeleaf guide

th:block 只是一个属性容器，允许模板开发人员指定他们想要的任何属性.Thymeleaf 会执行这些属性，然后简单地让块消失得无影无踪.

th:block is a mere attribute container that allows template developers to specify whichever attributes they want. Thymeleaf will execute these attributes and then simply make the block disappear without a trace.

因此它可能很有用，例如，当创建每个元素需要多个 <tr> 的迭代表时:

So it could be useful, for example, when creating iterated tables that require more than one <tr> for each element:

<table>
   <th:block th:each="user : ${users}">
      <tr>
         <td th:text="${user.login}">...</td>
         <td th:text="${user.name}">...</td>
      </tr>
      <tr>
         <td colspan="2" th:text="${user.address}">...</td>
      </tr>
   </th:block>
</table>
