如何让图片放大，大多数的UI组件都带有这种功能，今天给大家介绍的这个插件除了放大之外，还可以旋转、移动、翻转、旋转、二次放大（全屏）

实现

npm i v-viewer -S

main.js 中引入

import 'viewerjs/dist/viewer.css'
import Viewer from 'v-viewer'
Vue.use(Viewer)
//配置项
Viewer.setDefaults({
zIndexInline:9999
})

<div>
<div>
图片展示
</div>
<img class="img" v-for="(src,index) in srclist" :src=" src.src" :title="src.name" :key="index">
</div>
///   预览学法有两种
图片预览1
<div v-viewer>
<img class="img" v-for="(src,index) in srclist" :src=" src.src" alt="src.name" :title="src.name" :key="index"/> 
</div>
图片预览2
<viewer :images="srclist">
<img class="img" v-for="(src,index) in srclist" :src="index > 1 ? src.src: ''" :key="index"/> 
</viewer>
