前言

在实现文件预览的时候我们可以通过vue-office组件来实现文件的预览效果

效果图

docx文件

xlsx文件

pdf文件

vue中简单案例

1、安装组件

整体安装和分开安装：vue-demi可同时兼容vue3和vue2的组件库
npm install --save @vue-office/docx @vue-office/excel @vue-office/pdf vue-demi

//docx文档预览组件
npm install @vue-office/docx vue-demi
 
//excel文档预览组件
npm install @vue-office/excel vue-demi
 
//pdf文档预览组件
npm install @vue-office/pdf vue-demi

vue的版本是2.6的 还需要安装
@vue/composition-api

2、vue中代码

<template>
  <div class="vueOffice-container">
    <el-upload class="upload-demo" action="" 
     :on-change="handleChange" 
     :file-list="fileList" 
     :limit="1" 
     multiple
    >
      <el-button size="small" type="primary">点击上传</el-button>
      <div class="el-upload__tip">
        <slot name='tip'>
          请上传文件
        </slot>
      </div>
    </el-upload>
    <div style="width: 40%; height: 840px">
      <vue-office-docx v-if="isdocx" :src="url" @rendered="rendered" style="width: 100%; height: 100%" />
      <vue-office-excel v-if="isexcel" :src="url" @rendered="rendered" style="width: 100%; height: 100%" />
      <vue-office-pdf v-if="ispdf" :src="url" @rendered="rendered" style="width: 100%; height: 100%" />
    </div>
  </div>
</template>

<script>

    }
  },
  created () { },
  mounted () {
  methods: {
    rendered () {
      console.log('渲染完成')
    },
    previewFile (url) {
      // 根据文件格式显示预览内容
      const fileExtension = url.split('.').pop().toLowerCase()
      if (fileExtension === 'xlsx') {
        this.isexcel = true
        this.isdocx = false
        this.ispdf = false
      }
      if (fileExtension === 'docx') {
        this.isdocx = true
        this.isexcel = false
        this.ispdf = false
      }
      if (fileExtension === ('pdf' || 'PDF')) {
        this.isdocx = false
        this.isexcel = false
        this.ispdf = true
      }
    },
    handleChange (file, fileLists) {
      this.url = URL.createObjectURL(file.raw)
      this.previewFile(file.name)
    }

  }
}
