Vue实现简单图片切换效果

本文实例为大家分享了Vue实现简单图片切换的具体代码，供大家参考，具体内容如下

代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
    <title>图片切换</title>
    <style type="text/css">
        *{
            padding: 0;
            margin: 0;
        }
        #app{
           position: absolute;
           width: 100px;
           height: 100px;
           top: 100px;
           left: 400px;
        }
 
       #left{
           position: relative;
           top:-240px;
           left: -45px;
           font-size: 50px;
       }
 
       #right{
           position: relative;
           top: -300px;
           left: 595px;
           font-size: 50px;
       }
 
       a{
           color: black;
           text-decoration: none;
       }
    </style>
</head>
<body>
    <div id="app">
        <!-- 要轮询的图片 -->
      <img :src="imgArr[index]"/>
      <!-- 左箭头 -->
      <a href="javascript:void(0)" id="left" @click="prev" v-show="index!=0">《</a>
      <!-- 右箭头 -->
      <a href="javascript:void(0)" id="right" @click="next" v-show="index<imgArr.length-1">》</a>
    </div>
    <script>
        var app = new Vue({
            el: "#app",
            data: {
                imgArr:[
                    "img/1.jpg",
                    "img/2.jpg",
                    "img/3.jpg",
                    "img/4.jpg",
                    "img/5.jpg",
                ],
 
                index: 0,
 
            },
            methods: {
                prev: function(){
                    this.index--;
                },
                next: function(){
                    this.index++;
                },
            }
        })
    </script>
</body>
</html>

总结：

列表数据使用数组保存；
v-bind指令可以设置元素属性，如src ；
v-show和v-if都可以切换元素的显示状态，但频繁切换推荐使用v-show
