5,实现鼠标移入移出左右切换图片按钮的样式切换,使用css3中的:hover的样式
- <body>
- <div id="box">
- <button id="left" @click="left">//左侧点击按钮
- <
- </button>
- <img id="img":src="img[dindex]" >//轮播的图片采用动态绑定渲染
- <button id="right" @click="right">
- >
- </button>
- <ul>
- //采用v-for循环实现圆点的动态个数渲染
- <li v-for="(item,index) in img.length" @click="yuan(index)">
- //不同图片的渲染
- <img :src="index===dindex?'./圆点 .png':'./圆点2.png'" alt="">
- </li>
- </ul>
- </div>
- </body
- <style>
- //轮播图片的位置
