How to implement a scrolling list in uniapp

Uniapp is an efficient cross-platform development framework that can be used to develop WeChat applets, APPs, etc. In Uniapp, implementing scrolling lists is a common need and can be achieved by using components and some simple code. This article will introduce how to implement a scrolling list in uniapp and provide corresponding code examples.

Step 1: Create a scrolling list component
First, create a scrolling list component in Uniapp, which can be implemented using the <scroll-view></scroll-view> component. <scroll-view></scroll-view> is a container that supports scrolling, in which multiple sub-components can be placed to achieve a scrolling effect.

The sample code is as follows:

<template>
  <scroll-view class="list-wrapper" scroll-y>
    <div class="list-item" v-for="item in list" :key="item.id">
      {{ item.text }}
    </div>
  </scroll-view>
</template>

<script>
export default {
  data() {
    return {
      list: [
        { id: 1, text: '列表项1' },
        { id: 2, text: '列表项2' },
        { id: 3, text: '列表项3' },
        // ...更多列表项
      ]
    }
  },
}
</script>

<style>
.list-wrapper {
  height: 300px;  /* 设置滚动区域的高度 */
}
.list-item {
  height: 50px;  /* 设置每个列表项的高度 */
  line-height: 50px;
  padding: 0 20px;
  border-bottom: 1px solid #ccc;
}
</style>

In the above example, we created a scrolling list by using the <scroll-view></scroll-view> component, passing scroll- The y attribute implements vertical scrolling.

Step 2: Reference the scrolling list component in the page
Reference the scrolling list component just created on the page that needs to display the scrolling list, and pass the corresponding data.

The sample code is as follows:

<template>
  <view>
    <scroll-list></scroll-list>
  </view>
</template>

<script>
import scrollList from '@/components/scrollList'

export default {
  components: {
    scrollList
  },
}
</script>

In the above example, we introduced a scrolling list component named scrollList and used it in the page.

Summary
Through the above steps, we can implement a simple scrolling list in uniapp. First, we created a scrolling list component and used the <scroll-view></scroll-view> component to achieve the scrolling effect. We then referenced the component in the page and passed it the appropriate data. Through the above code examples, you can further explore more features and functions of implementing scrolling lists in uniapp.
