# ScrollList 横向滚动列表

该组件一般用于同时展示多个商品、分类的场景,也可以完成左右滑动的列表。

# 平台差异说明

App(vue) App(nvue) H5 小程序

# 基本使用

通过slot传入内容

<template>
    <up-scroll-list>
        <view v-for="(item, index) in list" :key="index">
            <image :src="item.thumb"></image>
        </view>
    </up-scroll-list>
</template>
<script setup>  
import { reactive } from 'vue';  
  
const list = reactive([  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/1.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/2.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/3.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/4.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/5.jpg"  
    }  
]);  
</script>
<script>
    export default {
        data() {
            return {
                list: [{
                    thumb: "https://cdn.uviewui.com/uview/goods/1.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/2.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/3.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/4.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/5.jpg"
                }]
            }
        }
    }
</script>

# 指示器的使用

  • indicator 用于控制指示器是否显示
  • indicatorWidth 用于控制指示器整体的宽度
  • indicatorBarWidth 用于控制指示器滑块的宽度
  • indicatorColor 指示器的颜色
  • indicatorActiveColor 滑块的颜色
  • indicatorStyle 指示器的位置/样式控制
<template>
    <up-scroll-list :indicator="indicator" indicatorColor="#fff0f0" indicatorActiveColor="#f56c6c">
        <view v-for="(item, index) in list" :key="index">
            <image :src="item.thumb"></image>
        </view>
    </up-scroll-list>
</template>
<script setup>  
import { reactive } from 'vue';  
  
const list = reactive([  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/1.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/2.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/3.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/4.jpg"  
    },  
    {  
        thumb: "https://cdn.uviewui.com/uview/goods/5.jpg"  
    }  
]);  
</script>
<script>
    export default {
        data() {
            return {
                list: [{
                    thumb: "https://cdn.uviewui.com/uview/goods/1.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/2.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/3.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/4.jpg"
                }, {
                    thumb: "https://cdn.uviewui.com/uview/goods/5.jpg"
                }]
            }
        }
    }
</script>

# 兼容性与性能

  • 此组件是在nvue中引入bindingx,此库类似于微信小程序wxs,目的是让js运行在视图层,减少视图层和逻辑层的通信折损,在nvue中会有更好的体验。
  • 此组件是在APP-VUE、H5、小程序中使用的是wxs。
  • 其他平台则使用js完成。

当滑动到最左边/最右边时,uview-plus提供了事件leftright可供调用,用于对列表滑动到端点处的业务实现。

<template>
    <up-scroll-list @right="right" @left="left">
        <view class="scroll-list" style="flex-direction: row;">
            <view
                class="scroll-list__goods-item"
                v-for="(item, index) in list"
                :key="index"
                :class="[(index === 9) && 'scroll-list__goods-item--no-margin-right']"
            >
                <image class="scroll-list__goods-item__image" :src="item.thumb"></image>
                <text class="scroll-list__goods-item__text">¥{{ item.price }}</text>
            </view>
            <view class="scroll-list__show-more">
                <text class="scroll-list__show-more__text">查看更多</text>
                <up-icon name="arrow-leftward" color="#f56c6c" size="12"></up-icon>
