vue 列表无限滚动列表，循环完自动切换tab

记录一下大屏常用的滚动组件 vue-seamless-scroll 以及滚动完自动切换tab效果。

1.下载vue-seamless-scroll插件

javascript">npm install vue-seamless-scroll --save

2.页面使用

javascript"><vueSeamlessScroll @ScrollEnd="changeScroll" :data="nowlist" :class-option="defaultOption" class="fxsfdw_list"><div v-for="(item, index) in nowlist" :key="index"><div class="ttflex"><div class="items w1">{{ item.name }}</div><div class="items w2">{{ item.age }}</div><div class="items w3">{{ item.class }}</div></div></div>//循环完一次增加间隔<div style="height: 20px;"></div>
</vueSeamlessScroll>
<script>
import vueSeamlessScroll from "vue-seamless-scroll"
export default {components: {vueSeamlessScroll},
}
</script>

3.监听列表滚动完毕执行定时任务

需要用到插件的一个方法 @ScrollEnd 官网没有介绍，这个方法是列表滚动完毕一次就会执行。

javascript">  methods: {jumptype() {clearTimeout(this.timeOut)this.active = this.active + 1console.log(this.active);if (this.active == 3) {this.active = 0this.nowlist = this.userInfo.list1} else if (this.active == 1) {this.nowlist = this.userInfo.list2} else if (this.active == 2) {this.nowlist = this.userInfo.list3}if (this.nowlist.length < 4) {this.timeOut = setTimeout(() => {this.jumptype()}, 3000);}}, //监听列表滚动完毕changeScroll() {if (this.nowlist.length) {this.jumptype()}}},

4.完整测试代码

注意滚动列表最好要定义高度，高度与你设置limitMoveNum 属性相关联否则列表滚动会有间隔！

javascript"><template><div><div class="tit_flex"><div class="tit_item" :class="active == index ? 'activeitem' : ''" v-for="(item, index) in classList" :key="index"@click="changeType(item, index)">{{ item.name }}</div></div><div class="content"><div class="tflex"><div class="items w1">姓名</div><div class="items w2">年龄</div><div class="items w3">班级</div></div><!-- 注意滚动列表最好要定义高度，高度与你设置limitMoveNum 属性相关联否则列表滚动会有间隔  !!!!!--><vueSeamlessScroll @ScrollEnd="changeScroll" :data="nowlist" :class-option="defaultOption" class="fxsfdw_list"><div v-for="(item, index) in nowlist" :key="index"><div class="ttflex"><div class="items w1">{{ item.name }}</div><div class="items w2">{{ item.age }}</div><div class="items w3">{{ item.class }}</div></div></div><div style="height: 20px;"></div></vueSeamlessScroll></div></div>
