  • step: 0.3                          ----内容信息滚动速度,数值越大速度滚动越快
  • limitMoveNum: 5,                 ----开始无缝滚动的数据量,可根据需滚动的内容进行配置

  • openWatch: true                  ----开启数据实时监控刷新dom
  • singleHeight: 0                    ----单步运动停止的高度(默认值0是无缝不停止的滚动) direction值为向上/向下(0/1)
  • singleWidth: 0                     ----单步运动停止的宽度(默认值0是无缝不停止的滚动) direction值为向左/向右(2/3)

2.1 页面处理

<template>
  <div class="table-demo-wrapper">
    <ul class="table-header">
      <li>
        <span>姓名</span>
        <span>性别</span>
        <span>年龄</span>
        <span>地址</span>
      </li>
    </ul>
    <vueSeamlessScroll :data="source" class="seamless-warp" :class-option="optionSingleHeightTime">
      <ul
        class="list"
        :style="'height:'+source.length*38+'px;'"
        @mousemove="stopScroll"
        @mouseout="doScroll"
      >
        <li
          :class="{devicelistitem: true, even: (index + 1) % 2 !== 0}"
          v-for="(item,index) in source"
          :key="index"
        >
          <span :title="item.name">{{item.name}}</span>
          <span :title="item.sex">{{item.sex}}</span>
          <span :title="item.age">{{item.age}}</span>
          <span :title="item.address">{{item.address}}</span>
        </li>
      </ul>
    </vueSeamlessScroll>
  </div>
</template>

2.2 逻辑处理

<script>
import vueSeamlessScroll from "vue-seamless-scroll";
export default {
  components: {
    vueSeamlessScroll,
  },
  data() {
    return {
      allowScroll: true,
      source: [],
    };
  },
  computed: {
    optionSingleHeightTime() {
      return {
        singleHeight: 38,
        waitTime: 3000,
        limitMoveNum: this.source ? this.source.length : 5,
      };
    },
  },
  mounted() {
    this.initData();
  },
  methods: {
    initData() {
      this.source = [];
      for (let i = 0; i < 30; i++) {
        this.source.push({
          name: `张三${i + 1}`,
          sex: "男",
          age: i + 1,
          address: "中国大陆浙江省杭州市西湖区",
        });
      }
    },
    stopScroll() {
      this.allowScroll = false;
    },
    doScroll() {
      this.allowScroll = true;
    },
  },
};
</script>

2.3 样式处理
