安装

npm install --save @vue-office/docx @vue-office/excel @vue-office/pdf vue-demi@0.14.6

vue-demi@0.14.6; 其中 @0.14.6 为版本号，可以不加，默认下载最新版。

如果是 vue2.6 版本或以下还需要额外安装 @vue/composition-api

npm install @vue/composition-api

使用

目录结构

src\components

直接上代码

src\components\FileView\doc\index.vue

应用实例

建议在main.js中增加全局组件引用

import FileView from '@/components/FileView'
Vue.component('FileView',FileView)

如果不使用全局挂载，那么请局部注册

我的使用场景

<FileView :open.sync="fileViewOpen" :url="fileUrl" v-if="fileViewOpen" />
