Question

尝试学习此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>

所以我需要一些能使IF语句生效的功能，该语句声明是否只有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。这是否可能？

您只需要构造车把块即可。车把控件不是HTML元素，因此您可以将部分HTML结构包装在if语句中。

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}}

handlebars.js并隐藏列表
