月亮的影子倒印在江面，宛如一个害羞的小姑娘，发出淡淡的光芒，桥上星星点点的路灯灯光，像一颗颗小星星，为人们照亮前方的道路，闭上眼睛，风夹带着蟋蟀的歌声，荡漾在路上。
本文实例为大家分享了vue实现列表无缝循环滚动的具体代码，供大家参考，具体内容如下
功能介绍：
在PC端网页，包括大数据、官网、后台管理平台开发中，可能会用到这种列表循环滚动的展示。
大致需求：
1、列表可以使用数组循环遍历；2、每隔几秒中列表数据向上滚动一定距离，展示下一条数据；3、滚动到最后一条数据时重新显示第一条开始的数据（类似走马灯、banner图的循环效果）；
整体思路：
1、使用两个定时器嵌套实现；2、需要两个相同容器存放同样内容，实现无缝衔接效果；
效果展示：

setInterval踩坑：
发现这种方法实现的定时轮播，有一阵没访问页面，会出现卡停的情况，采用下面的解决方法：
<script>
new Vue({
el: '#app',
data: {
tableHei: 'auto',
timer: null,
size: 0,
stopSign: true, // 判断定时器是否停止标识
stepTime: null, // 改为全局定时器
},
mounted() {
const that = this;
// 增加浏览器激活状态判断。非激活状态为onblur
window.onfocus = function(e) {
const tableBox = that.$refs.tableBox;
const sT = tableBox.scrollTop;
console.log("激活状态！")
if (!that.stopSign) {
tableBox.scrollTop = Math.round(sT / 50) * 50;
clearInterval(that.stepTime);
}
}
this.getTable();
},
methods: {
getTable() {
const outHei = this.$refs.tableoOut.clientHeight - 60;
this.size = Math.floor(outHei / 50);
this.tableHei = this.size * 50 + 'px';
this.scrolls();
},
stepScroll() {
const that = this;
const step = 50;
let num = 0;
const tableBox = this.$refs.tableBox;
// 改为全局定时器，且在调用前先进行清空
clearInterval(this.stepTime);
this.stepTime = setInterval(function () {
that.stopSign = false;
num += 2;
if (num > step) {
num = 0;
clearInterval(that.stepTime);
that.stopSign = true;
} else {
tableBox.scrollTop += 2;
}
}, 1000 / 60);
},
scrolls() {
const that = this;
const tableBox = this.$refs.tableBox;
const tableInner = this.$refs.tableInner;
clearInterval(this.timer);
this.timer = setInterval(function () {
// 修改定时器结束判断条件
if(tableBox.scrollTop >= tableInner.scrollHeight) {
tableBox.scrollTop = 0;
}
that.stepScroll();
}, 2000);
},
}
})
</script>
