本文实例为大家分享了vue实现匀速轮播效果的具体代码，供大家参考，具体内容如下

不多描述了 直接代码吧

<template>
 <div>
 <div class="box">
  <ul class="ullist" @mouseleave="clearTimeout" @mouseenter="beginTimeout">
  <li><img src="@/assets/401_images/401.gif" alt="" class="Liwidth"></li>
  <li><img src="@/assets/404_images/404.png" alt=""></li>

 methods:{
  //获取窗口的宽度
 getListLeng(){
  this.boxWidth = document.getElementsByClassName('box')[0].offsetWidth
  var ul = document.getElementsByClassName('ullist')[0]
  var length = ul.children.length
  ul.style.width=length*230+'px'
  this.runTimeout(ul,this.boxWidth,length)
 },
 //轮播效果
 runTimeout(ul,boxWidth,length){
  let that = this
  this.timer=setInterval(function(){
  // move();

  that.move(ul,boxWidth,length)
  },50)
 },
 //轮播图走的方法

 },
 //页面销毁的时候 关闭定时器
 destroyed () {
