获取 jQuery 模板数组中的第一项
Grab the first item in jQuery Template array
我有一个数组 sizes，我可以在我的 jQuery 模板中访问它。但是，在某些情况下，数组只有一个项目，我想直接访问它。如何使用 jQuery 模板执行此操作？
此尝试无效：
<input type="hidden" name="product_id" data-related-product-id="${$index}" value="${sizes[0]}${product_id}" />
并输出：
<input type="hidden" value="[object Object]{product_id}" data-related-product-id="1" name="product_id">
我似乎找不到有关如何执行此操作的任何文档。
这是 sizes 上 JSON.stringify 的输出。

基于size数组结构，你将不得不做这样的事情：
${sizes['somethingHere'][0]}.
您可以使用 JSON.stringify(sizes) 转储并查看 [object Object] 包含的内容。
编辑：
将代码中的 ${sizes[0]}${product_id} 替换为 ${sizes[0]['product_id']}。这应该让你成为数组中的第一个元素（如果只有一个元素，则为唯一元素）。
使用 ${sizes[0]['product_id']}，这将为您提供产品数组中第一个产品的产品 ID。
很高兴，您的问题已解决。
快乐编码:-)
