css 复制代码

// css
<style lang="scss">
  .scroll-list {
	display: flex;
	flex-direction: column;
      .scroll-list__row {
        display: flex;
        flex-direction: row;
        margin-top:5rpx;
     }
     .scroll-list__goods-item {
       display: flex;
       flex-direction: column;
       align-items: center;
    }
}

<style>

如果下面的指示器跟上面的滑动不同步的情况下用下面的代码

javascript 复制代码

<template>
  <u-scroll-list @scroll="handleScroll">
    <view class="scroll-list margin-top-xs" ref="scrollList">
      <!-- 第一行 -->
      <view class="scroll-list__row">
        <view
          class="scroll-list__goods-item"
          style="width: 248rpx;height:120rpx;display:flex;justify-content: center;align-items:center"
          v-for="(item, index) in list.slice(0, 6)" 
          :key="'row1-' + index"
          :class="[(index === 4) && 'scroll-list__goods-item--no-margin-right']"
        >
          <text>{{item.name}}</text>
