VUE实现自动滚动简单示例

<el-card class="text" name="scrollBox">
  文本内容
</el-card>

height: 600px;
overflow: auto;

    updateScrollTop() {
      const scrollList = document.getElementsByName('scrollBox')
      for (let i = 0; i < scrollList.length; i++) {
        const x = scrollList[i]
        this.scrollThen(x).then()
      }
    },
    async scrollThen(x) {
      do {
        await new Promise(resolve => {
          setTimeout(() => {
            resolve()
          }, 100)
        })
        if (parseFloat(x.clientHeight / x.scrollHeight) < 0.8) {
          if (x.scrollHeight - x.scrollTop === x.clientHeight) {
            x.scrollTop = 0
          } else {
            x.scrollTop++
          }
        }
      } while (true)
    }

  mounted() {
    this.updateScrollTop()
  }

mounted() {
  this.$nextTick(() => {
      setTimeout(() => {
        window.scrollTo({ top: 657, behavior: "smooth" })
      }, 200)
    })
  },
// top滚动位置
