<template>
  <div class="wrapper">
    <div class="roll-box">
      <ul class="roll-list" :class="{ roll_top: rollConfig.animate }">
        <li v-for="(item, index) in rollConfig.data" :key="index">
          {{ item }}
        </li>
      </ul>
    </div>

</template>
 

2、方法

<script>
export default {
  data() {
    return {
      // 滾動配置
      rollConfig: {
        animate: false,
        data: ['1', '2', '3', '4', '5', '6', '7', '8', '9'],
      },
    }
  },
  mounted() {
    setInterval(this.showroll, 2000)
  },
  methods: {
    showroll() {
      this.rollConfig.animate = true
      setTimeout(() => {
        this.rollConfig.data.push(this.rollConfig.data[0])
        this.rollConfig.data.shift()
        this.rollConfig.animate = false
      }, 500)
    },
  },
}
</script>
