Aem 如何在数据列表中添加条件元素？

我目前有一个数据列表，它填充一个JS数组，如下所示：

          var infoWindowContent = [
              <div data-sly-use.ed="Foo"
                   data-sly-list="${ed.allassets}"
                   data-sly-unwrap>
                   ['<div class="info_content">' +
                   '<h3>${item.assettitle @ context='unsafe'}</h3> ' +
                   '<p>${item.assettext @ context='unsafe'} </p>' + '</div>'],
               </div>
               ];

---

看看这里的示例，我会将此逻辑放入JS USe api中以填充此数组。

要快速回答您的问题，可以在列表中设置一个条件（使用

数据sly test

），如下所示：

<div data-sly-list="${ed.allAssets}">
    <h3>${item.assettitle @ context='html'}</h3>
    <img data-sly-test="${item.assetFormat == 'image/png'}" src="${item.assetImgLink}"/>
    <p data-sly-test="${item.assetFormat == 'text/html'}">${item. assetText @ context='html'}"</p>
</div>

对于JS中的标记，我宁愿将其移动到客户端JS，以便相应的Foo.java逻辑只构建JSON内容，而不构建任何内部标记
