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 luckyexcel2.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>
