Common usage of V-Viewer and hidden img tags or img tags are not directly under <viewer>

v-viewer installation

npm install v-viewer --save

use

I use it globally, under main.js

import 'viewerjs/dist/viewer.css'
import Viewer from 'v-viewer';
Vue.use(Viewer);

Common usage

<viewer :images="imgList">
	<img v-for="src in imgList"  src="src"/>
</viewer>

Do not directly use img as a subtag

In my project, my img is included in other components and cannot be directly included in the tag. In this case, you need to use the v-viewer command on the parent node that uses v-for

<div class="blog-img-list clearfix" @click.stop="" v-viewer>
        <div class="blog-img-item" v-for="(item,index) in imgList"  >
            <el-image :src="blogImgPath+item" fit="cover" >
                <div slot="error" class="image-slot" >
                    <i class="el-icon-picture-outline"></i>
                </div>
            </el-image>
        </div>
    </div>

Hide img tag

Sometimes we don’t need to display the picture, such as using text like [View Picture] to open the picture, then we need another way to open v-viewer

<template>
    <span class="img-text">
        <el-link v-for="(img,index) in imgList" type="primary" @click="show(index)" >[查看图片]</el-link>
        <viewer :images="imgList"  class="viewer" ref="viewer"
                @inited="inited">
            <img   v-for="img in imgList" :src="img"/>
        </viewer>
    </span>
</template>

<script>
    export default {
        name: "ImageText",
        props: ['imgList'],
        methods: {
            inited (viewer) {
                this.$viewer = viewer
            },
            show(index) {
                this.$viewer.view(index)
            }
        }
    }
</script>

<style scoped>
    img{
        display: none;
    }
</style>

Hide img, and use $viewer.view to pass in index to open
