本文主要包含vue示例,vue.js示例,vue轮播组件,vue轮播图组件,vue组件等相关知识,流火行者 希望在学习及工作中可以帮助到您
本人刚学习vue,用vue做了个图片轮播，下面我来记录一下,有需要了解VUE开发一个图片轮播的组件的朋友可参考。希望此文章对各位有所帮助。
完成效果图如下：
vue开发的思路主要是数据绑定，代码如下：
<template>
<div ref="root" style="user-select: none;-webkit-user-select: none;overflow: hidden">
<div class="sliderPanel"
:class="{transitionAni:ani}"
:style="{height:height,transform:translateX}">
<div v-for="item in itemList" class="verticalCenter picbox" :style="{left:item.x+'px'}">
<img :style="{width:width,top:top}" :src="item.url" style="min-height: 100%">
</div>
</div>
<div @click="clickLeft" class="arrowLeft verticalCenter horizaCenter">
<img src="./image/arrow.png" style="transform: rotate(180deg)">
</div>
<div @click="clickRight" class="arrowRight verticalCenter horizaCenter">
<img src="./image/arrow.png">
</div>
<div class="arrowBottom verticalCenter horizaCenter" >
<img src="./image/arrow.png" style="transform: rotate(90deg) scale(0.7)">
</div>
<div class="sliderBar horizaCenter">
<div v-for="(item,index) in imgArray" @click="clickSliderCircle(index)" class="circle" :class="{circleSelected:item.selected}">
</div>
</div>
</div>
</template>
