How can I create a hierarchical product category structure in a uniapp小程序?

To create a hierarchical product category structure, you can use the following steps:

Create a new folder for your product categories.
In the folder, create a file for each category.
In each category file, define the category's name and parent category (if any).
Save the category files.

For example, if you have a product category structure like this:

<code>Categories:
  - Clothing
    - Shirts
    - Pants
    - Shoes
  - Electronics
    - Computers
    - Phones
    - Tablets</code>

What are the best practices for handling product category linkage events in a uniapp小程序?

When handling product category linkage events, it is important to follow these best practices:

Use a consistent naming convention for your events. This will make it easier to identify and handle events.
Use descriptive event names. This will help you to understand what the event is about.
Provide detailed event data. This will help you to troubleshoot any issues that may arise.
Handle events in a centralized location. This will make it easier to maintain your code.

How can I dynamically fetch and display nested product categories in a uniapp小程序?

To dynamically fetch and display nested product categories, you can use the following steps:

Create a function to fetch the product categories.
Call the function in the onLoad method of the product category page.
Use the fetched product categories to populate a list or tree view.

For example, the following code shows how to fetch and display nested product categories in a uniapp小程序:

<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>

    <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>

로그인 후 복사

<code class="javascript">// api/category.js
import request from '@/utils/request.js'

export function getCategories() {
  return request({
    url: '/categories',
    method: 'GET'
  })
}</code>
