handlebars.js 并隐藏 if 列表

handlebars.js and hide if list

正在努力学习这个handlebars.js,目前我有:

<ul class="productView-thumbnails"{{#gt product.images.length 5}} data-slick='{
                "infinite": false,
                "mobileFirst": true,
                "slidesToShow": 5,
                "slidesToScroll": 1
            }'{{/gt}}>
            {{#each product.images}}
                <li class="productView-thumbnail">
                    <a
                        class="productView-thumbnail-link"
                        href="{{getImage this 'product_size' (cdn ../theme_settings.default_image_product)}}"
                        data-image-gallery-item
                        data-image-gallery-new-image-url="{{getImage this 'product_size' (cdn ../theme_settings.default_image_product)}}"
                        data-image-gallery-zoom-image-url="{{getImage this 'zoom_size' (cdn ../theme_settings.default_image_product)}}">
                        <img class="lazyload" data-sizes="auto" src="{{cdn 'img/loading.svg'}}" data-src="{{getImage this 'productview_thumb_size' (cdn ../theme_settings.default_image_product)}}" alt="{{this.alt}}" title="{{this.alt}}">
                    </a>
                </li>
            {{/each}}
        </ul>

所以我需要一些 IF 语句的效果,如果只有 1 张图像 (li),然后将 display:none 应用于 class productView-thumbnails

如果只返回一个 LI,我试图隐藏整个 UL。这可能吗?

您应该只需要构造您的车把块。车把控件不是 HTML 元素,因此您可以在 if 语句中包装部分 HTML 结构。

考虑到您已经注册了 gt-helper:

{{#gt product.images.length 1}}
<ul class="productView-thumbnails"{{#gt product.images.length 5}} data-slick='{
…}'{{/gt}}>
{{/gt}}
{{#each product.images}}
  {{#gt product.images.length 1}}
            <li class="productView-thumbnail">
  {{/gt}}
  …
  {{#gt product.images.length 1}}
  </li>
  {{/gt}}
{{/each}}
…
{{#gt product.images.length 1}}
</ul>
{{/gt}}
