如何在 Thymeleaf 中拆分字符串 [英] How to split string in Thymeleaf

问题描述

我有像 wange/25011.jpg|wange/25011-1.jpg 或 null 之类的图像名称，我想将它们拆分为 wange/25011.jpg 和 wange/25011-1.jpg，如果为空则不拆分.我尝试了如下代码，但没有成功...

<td th:if="${brickset.imageNames} != null" th:each="image : ${#strings.arraySplit(brickset.imageNames, '|')}"><a href="#" th:href="${imageBaseUrl + image}"><img src="#" th:src="${imageBaseUrl + image}" height="64"/></a></td>

解决方案

这是我自己的答案:

<tr th:each="brickset : ${bricksets}" th:alt="${brickset.description}"><td><div th:unless="${brickset.imageNames == null}"><div th:each="image,status : ${#strings.arraySplit(brickset.imageNames, '|')}"><a href="#" th:href="${imageBaseUrl + image}" th:remove="${image} == null ? tag" th:title="${brickset.brand.name}"><img src="#" th:src="${imageBaseUrl + image}" height="64" th:remove="${status.index} > 0 ? tag"/></a>

</td></tr></tbody>

I have imageNames like wange/25011.jpg|wange/25011-1.jpg or null, I want to split them to wange/25011.jpg and wange/25011-1.jpg, or no split if null. I tried code as below, but no work...

<td th:if="${brickset.imageNames} != null"  th:each="image : ${#strings.arraySplit(brickset.imageNames, '|')}">
    <a href="#" th:href="${imageBaseUrl + image}">
        <img src="#" th:src="${imageBaseUrl + image}" height="64"/>
    </a>
</td> 

解决方案

Here is my own answer:

<tbody id="portfolio" class="clear fix">
  <tr th:each="brickset : ${bricksets}" th:alt="${brickset.description}">
    <td>
      <div th:unless="${brickset.imageNames == null}">
        <div th:each="image,status : ${#strings.arraySplit(brickset.imageNames, '|')}">
          <a href="#" th:href="${imageBaseUrl + image}" th:remove="${image} == null ? tag" th:title="${brickset.brand.name}">
            <img src="#" th:src="${imageBaseUrl + image}" height="64" th:remove="${status.index} > 0 ? tag"/>
          </a>
        </div>
      </div>
    </td>
  </tr>
</tbody>
