#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>
    <u-scroll-list :indicator="indicator" indicatorColor="#fff0f0" indicatorActiveColor="#f56c6c">
        <view v-for="(item, index) in list" :key="index">
            <image :src="item.thumb"></image>
        </view>
    </u-scroll-list>
</template>

<script>
    export default {
        data() {
            return {
                indicator: true,
                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"
                }]
            }
        }
    }

#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提供了事件left和right可供调用，用于对列表滑动到端点处的业务实现。

<template>
    <u-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>
                <u-icon name="arrow-leftward" color="#f56c6c" size="12"></u-icon>
            </view>
        </view>
    </u-scroll-list>
