VUE中用原生js实现轮播图效果

本文主要是介绍VUE中用原生js实现轮播图效果，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

代码如下：

HTML部分：

<div class="mainBlock"><!--显示的窗口--><div class="displayWindow"><!--可移动面板--><div class="mobilePanel" style="position: relative;left: 0;"><div class="box" v-bind:key="index" v-for="(item, index) in productList"><div class="boxLeft"><div style="width: 100%;height: 100%;display: flex;justify-content: center"><img :src="item.picSrc" :width="item.picWidth" height="80px" style="margin-top: 14px"/></div></div><div class="boxRight"><p class="proTitle">{{item.ProductName}}</p><p class="proText">{{item.Description}}</p></div></div></div></div></div>

CSS部分：

.mainBlock {width: 1080px;margin: 0 auto;padding: 20px 0;height: 150px;}.displayWindow {width: 100%;height: 100%;overflow: hidden}.mobilePanel {width: 3240px;height: 100%;}.box {float: left;width: 270px;height: 120px;background: url(../assets/images/item_bg.jpg) no-repeat center bottom;}.boxLeft {width: 115px;float: left;height: 100%;}.boxRight {width: 135px;float: left;}.proTitle {line-height: 30px;font-size: 14px;margin: 2px auto;}.proText {color: #666;line-height: 180%;font-size: 12px;margin: 2px auto;}

JS部分：
