<link href="//path/viewer.css" rel="stylesheet"> <script src="//path/vue.js"></script> <script src="//path/viewer.js"></script> <script src="//path/v-viewer.js"></script> ... <script> Vue.use(VueViewer.default) </script>
CommonJS
var VueViewer = require('VueViewer')
AMD
require(['VueViewer'], function (VueViewer) {});
Usage of directive
Just add the directive v-viewer
to any element, then all img
elements in it will be handled by viewer
.
You can set the options like this: v-viewer="{inline: true}"
Get the element by selector and then use el.$viewer
to get the viewer
instance if you need.
<template> <div id="app"> <div class="images" v-viewer="{movable: false}"> <img v-for="src in images" :src="src" :key="src"> </div> <button type="button" @click="show">Show</button> </div> </template> <script> import 'viewerjs/dist/viewer.css' import Viewer from 'v-viewer' import Vue from 'vue' Vue.use(Viewer) export default { data() { images: ['1.jpg', '2.jpg'] }, methods: { show () { const viewer = this.$el.querySelector('.images').$viewer viewer.show() } } } </script>
Direcitve modifiers
static
The viewer
renderer will be executed only once after the directive binded.
If you're sure the images inside this element won't change again, use it to avoid unnecessary re-render.
<div class="images" v-viewer.static="{inline: true}"> <img v-for="src in images" :src="src" :key="src"> </div>
Usage of component
You can simply import the component and register it locally too.
Use scoped slot to customize the presentation of your images.
Listen for the inited
event to get the viewer
instance, or use this.refs.xxx.$viewer
.
<template> <div id="app"> <viewer :options="options" :images="images" @inited="inited" class="viewer" ref="viewer" > <template slot-scope="scope"> <img v-for="src in scope.images" :src="src" :key="src"> {{scope.options}} </template> </viewer> <button type="button" @click="show">Show</button> </div> </template> <script> import 'viewerjs/dist/viewer.css' import Viewer from "v-viewer/src/component.vue" export default { components: { Viewer }, data() { images: ['1.jpg', '2.jpg'] }, methods: { inited (viewer) { this.$viewer = viewer }, show () { this.$viewer.show() } } } </script>
You can replace images
with trigger
, to accept any type of prop. when the trigger
changes, the component will re-render the viewer.
<viewer :trigger="externallyGeneratedHtmlWithImages"> <div v-html="externallyGeneratedHtmlWithImages"/> </viewer>
