本文示例都是用小程序写的，然而不影响要实现的性能。
wxml
装图片的盒子多复制一份，让循环图片的首尾相接
<view class="scrollbox dis-flex"> <view class="imgItem dis-flex" style="animation: {{computedAni}};"> <image src="../img/{{index + 1}}.jpg" wx:for="{{images}}" mode="aspectFill" wx:key="index"></image> </view> <view class="imgItem dis-flex" style="animation: {{computedAni}};"> <image src="../img/{{index + 1}}.jpg" wx:for="{{images}}" mode="aspectFill" wx:key="index"></image> </view></view>wxss
.dis-flex { display: flex; display: -webkit-flex;}.scrollbox { margin: 30px; text-align: center; border: 1px solid blue; height: 220rpx; align-items: center; overflow: hidden;}.imgItem { animation: 24s rowup linear infinite normal;}.imgItem image { width: 200rpx; height: 200rpx; margin: 0 20rpx;}@keyframes rowup { 0% { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } 100% { -webkit-transform: translate3d(-100%, 0, 0); transform: translate3d(-100%, 0, 0); }}@-webkit-keyframes rowup { 0% { -webkit-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } 100% { -webkit-transform: translate3d(-1000px, 0, 0); transform: translate3d(-1000px, 0, 0); }}js
调整速度的要害就在，动画的工夫是由循环的我的项目个数动态控制的
Page({ data: { images: new Array(4), computedAni: '' }, onLoad: function () { this.setAniSpeed(this.data.images.length) }, setAniSpeed (num) { let time = Math.ceil(num / 5 * 15) // 这里是以5张图片的时候，动画工夫15s为基准,能够本人调节 this.setData({ computedAni: `${time}s rowup linear infinite normal` }) }})点击这里能够查看代码片段
