vue读取本地的excel文件并显示在网页上

我想实现读取一个本地的xlsx文件(task_list.xlsx)而后显示在网页上, 一开始选择的方法是建个express server, 经过发送axios请求来实现, 可是以为只是读取一个本地文件还要搞个server太复杂了, 最终仍是经过"xlsx"模块 + axios实现了读取本地文件, 无需后端, 步骤以下:vue

1.经过vue-cli新建项目:
ios

2.编写分析excel workbook的脚本
/src/scripts/read_xlsx.jsgit

const XLSX = require('xlsx')

//将行,列转换
function transformSheets(sheets) {
  var content  = []
  var content1 = []
  var tmplist = []
  for (let key in sheets){
    //读出来的workbook数据很难读,转换为json格式,参考https://github.com/SheetJS/js-xlsx#utility-functions
    tmplist.push(XLSX.utils.sheet_to_json(sheets[key]).length)
    content1.push(XLSX.utils.sheet_to_json(sheets[key]))
  }
  var maxLength = Math.max.apply(Math, tmplist)
  //进行行列转换
  for (let y in [...Array(maxLength)]){
    content.push([])
    for (let x in [...Array(tmplist.length)]) {
      try {
        for (let z in content1[x][y]){
          content[y].push(content1[x][y][z])
        }
      } catch (error) {
        content[y].push(' ')
      }
    }
  }
  content.unshift([])
  for (let key in sheets){
    content[0].push(key)
  }
  return content

}

export {transformSheets as default}

3.新建一个组件
/src/components/task_list.vuegithub

<template>
  <div class="task-list">
    <p v-if="err!==''">{{err}}</p>  <!-- 用来显示报错 -->
    <table style="margin:0 auto;" v-if="content!==''">  <!-- 设置居中,若是没获取到内容则不显示 -->
      <tr><th v-for="h in content[0]" :key="h.id">{{h}}</th></tr>  <!-- 循环读取数据并显示 -->
      <tr v-for="row in content.slice(1,)" :key=row.id>
        <td v-for="item in row" :key=item.id>{{item}}</td>
      </tr>
    </table>
  </div>
</template>

<script>
import axios from 'axios'
import XLSX from 'xlsx'
import transformSheets from '../scripts/read_xlsx'    //导入转制函数

export default {
  name: 'TaskList',
  data: function () {
    return {
      content: '',    //初始化数据
      err: ''
    }
  },
  created() {
    var url = "/task_list.xlsx"  //放在public目录下的文件能够直接访问
    
    //读取二进制excel文件,参考https://github.com/SheetJS/js-xlsx#utility-functions
    axios.get(url, {responseType:'arraybuffer'})
    .then((res) => {
        var data = new Uint8Array(res.data)
    var wb = XLSX.read(data, {type:"array"})
    var sheets = wb.Sheets
    this.content = transformSheets(sheets)
    }).catch( err =>{
      this.err = err
    })
  }
}

大功告成,编译而后部署到服务器吧vue-cli

npm run build

部署就不详述了,把dist目录丢到服务器上就行.

效果就是这样,编程新手,就这个东西断断续续搞了快一周了...express
