本文提供如何在uniapp小程式中建立分層產品類別結構以及處理產品類別連動事件的指南。它還解釋瞭如何動態獲取和顯示嵌套產品類別。 ha
要建立分層產品類別結構,可以使用以下步驟:
例如,如果你有一個像這樣的產品類別結構:
<code>Categories: - Clothing - Shirts - Pants - Shoes - Electronics - Computers - Phones - Tablets</code>
你將創建以下檔案:
<code>/categories/clothing.js: export default { name: 'Clothing' }</code>
<code>/categories/clothing/shirts.js: export default { name: 'Shirts', parentCategory: '/categories/clothing' }</code>
<code>/categories/clothing/pants.js: export default { name: 'Pants', parentCategory: '/categories/clothing' }</code>
<code>/categories/clothing/shoes.js: export default { name: 'Shoes', parentCategory: '/categories/clothing' }</code>
<code>/categories/electronics.js: export default { name: 'Electronics' }</code>
<code>/categories/electronics/computers.js: export default { name: 'Computers', parentCategory: '/categories/electronics' }</code>
<code>/categories/electronics/phones.js: export default { name: 'Phones', parentCategory: '/categories/electronics' }</code>r
<code>/categories/electronics/tablets.js: export default { name: 'Tablets', parentCategory: '/categories/electronics' }</code>
處理產品類別連結事件時,它是遵循這些最佳實踐很重要:
要動態取得並顯示巢狀的產品類別,可以使用下列步驟:
onLoad
方法。 例如,以下程式碼展示如何在uniapp小程式中取得和顯示嵌套的產品類別:
<code class="javascript">import Vue from 'vue' import App from './App.vue' Vue.config.productionTip = false new Vue({ render: h => h(App) }).$mount('#app')</code>
<code class="javascript">// App.vue <template> <div> <ul> <li v-for="category in categories" :key="category.id"> {{ category.name }} <ul> <li v-for="subcategory in category.subcategories" :key="subcategory.id"> {{ subcategory.name }} </li> </ul> </li> </ul> </div> </template> <script> import { getCategories } from '@/api/category.js' export default { data() { return { categories: [] } }, async onLoad() { const res = await getCategories() this.categories = res.data } } </script></code>
<code class="javascript">// api/category.js import request from '@/utils/request.js' export function getCategories() { return request({ url: '/categories', method: 'GET' }) }</code>
