概要

Vue实现在线编辑excel、导入、导出

整体架构流程

luckysheet文档地址

exceljs文档地址

1.npm安装依赖

npm i exceljs file-saver luckyexcel

2.index.html中引入




Vue引入luckysheet，index.html头部标签head中引入（luckysheet文件在node_modules中）




  <link rel='stylesheet' href='./luckysheet/plugins/plugins.css' />
  <link rel='stylesheet' href='./luckysheet/css/luckysheet.css' />
  <link rel='stylesheet' href='./luckysheet/assets/iconfont/iconfont.css' />
  <script src="./luckysheet/plugins/js/plugin.js"></script>
  <script src="<%= BASE_URL %>./luckysheet/luckysheet.umd.js"></script>













3.组件实现










<template>
    <div class="test2">
      <div class="mb-md">
        <input type="file" @change="chageFile" ref="inputFile" />
        <button class="blueBtn" @click="exportExcelBtn">导出xlsx</button>
        <button v-if="bgbsm" class="blueBtn" @click="zxClicked">最新任务清单</button>
        <button v-if="!bgbsm" class="blueBtn" @click="editClicked">编辑</button>
        <button v-if="!bgbsm" class="blueBtn" @click="save">保存</button>
      </div>
      <!--web spreadsheet组件-->
      <div class="excel">
        <div id="luckysheetDom" style="margin: 0px; padding: 0px; width: 100%; height: 100%"></div>
      </div>
    </div>
  </template>
