点击图片放大预览功能实现

1、npm install v-viewer --save

2、在main.js中写以下代码

import Vue from 'vue';
import Viewer from 'v-viewer'
import 'viewerjs/dist/viewer.css'

Vue.use(Viewer);
Viewer.setDefaults({
  Options: { "inline": true, "button": true, "navbar": true, "title": true, "toolbar": true, "tooltip": true, "movable": true, "zoomable": true, "rotatable": true, "scalable": true, "transition": true, "fullscreen": true, "keyboard": true, "url": "data-source" }
});
3、把图片用<viewer>图片</viewer>包起来，或者在图片行间加上v-viewer,就完成了（仅限于在vue中使用）
