Vue导出json数据到Excel电子表格

工作笔记记录

一、安装依赖

npm install file-saver --save
npm install xlsx --save
npm install script-loader --save-dev

二、下载两个所需要的js文件  Blob.js 和 Export2Excel.js

http://xiazai.jb51.net/201708/yuanma/Export2Exce_jb51.rar

　　

三、src目录下新建vendor文件夹，将Blob.js 和 Export2Excel.js放进去

 

四、更改webpack.base.conf.js配置

五、vue

html部分：

<el-button type="primary" :loading="downloadLoading" @click="handleDownload" icon="el-icon-download">导出数据库</el-button>

        <el-table
            :data="tableData5"
            style=" 100%">
            <el-table-column type="expand">
            <template slot-scope="props">
                <el-form label-position="left" inline class="demo-table-expand">

<script>
export default {

      import("@/vendor/Export2Excel").then(excel => {
        const THEADER = ["箱码","单品条码","产品名称","规格",件规","件数","包数","单价","网店管家库存","总库存","成本"];  //  excell表头
        const FILETERVAL = ["id","name","desc","desc","desc","desc","desc","desc","desc","desc","desc"];  // filterVal是data中tableData5的key值，也是要自己写的。  ps: 忽略我的相同key:desc
        const DATA = this.formatJson(FILETERVAL, this.tableData5);
        excel.export_json_to_excel({
          header: THEADER,

    },
    formatJson(filterVal, jsonData) {
