方式一 ：vue-json-excel
这种方式会导出xls后缀的格式
参考：使用vue-json-excel生成并导出excel_finedayforu的博客-CSDN博客这里我们用到了一个库: vue-json-excel该库的npm地址:https://www.npmjs.com/package/vue-json-excel一. 安装vue-json-excelnpm install vue-json-excel在main.js中导入此模块import JsonExcel from "vue-json-excel";并在Vue对象上绑定此组件Vue...https://blog.csdn.net/finedayforu/article/details/115167417
1、引入vue-json-excel
cnpm i -S vue-json-excel2、 main.js中全局注册
import JsonExcel from 'vue-json-excel'
Vue.component('downloadExcel', JsonExcel)3、使用
<!--home-->
<template><div class="home"><download-excelclass="export-excel-wrapper":data="json_data":fields="json_fields"type="xls"worksheet="My Worksheet"name="用户信息"><el-button>导出EXCEL</el-button></download-excel></div>
</template><script>
export default {data() {return {json_fields: {年龄: "age", //常规字段姓名: "info.name", //支持嵌套属性密码: {field: "info.phone",//自定义回调函数callback: value => {return `+86 ${value}`;}}},json_data: [{age: 22,info: {name: "张三",phone: 12222222222},sex: "男"},{age: 23,info: {name: "李四",phone: 13333333333},sex: "女"}]// json_meta: [// [// {// " key ": " charset ",// " value ": " utf- 8 "// }// ]// ]};}
};
</script><style lang="scss" scoped>
.home {height: 100%;background-color: rgb(128, 126, 126);
}
</style>在这里说明一下组件的各个属性
- json_data：需要导出的数据
- json_fields：自主选择要导出的字段，若不指定，默认导出全部数据中心全部字段
| 属性名 | 类型 | 描述 |
|---|---|---|
| data | Array | 需要导出的数据，支持中文 |
| fields | Object | 定义需要导出数据的字段 |
| name | String | 导出excel的文件名 |
| type | String | 导出excel的文件类型（xls,csv）,默认是xls |
注意：还可以指定fetch属性动态获取数据，只需在其回调中返回tableData即可
<template><div id="app"><hr><h2>Fetch Example</h2><downloadexcelclass = "btn":fetch = "fetchData":fields = "json_fields":before-generate = "startDownload":before-finish = "finishDownload">Download Excel</downloadexcel></div>
</template><script>
import downloadexcel from "vue-json-excel";
import axios from 'axios';export default {name: "App",components: {downloadexcel,},data(){return {json_fields: {'Complete name': 'name','Date': 'date',},}}, //datamethods:{async fetchData(){const response = await axios.get('https://holidayapi.com/v1/holidays?key=a4b2083b-1577-4acd-9408-6e529996b129&country=US&year=2017&month=09');console.log(response);return response.data.holidays;},startDownload(){alert('show loading');},finishDownload(){alert('hide loading');}}
};
</script>4、效果图
方式二【推荐】：file-saver、xlsx、script-loader
经测试，导出15个字段情况下，最多可导出20万条记录，耗时20秒左右
1、引入依赖
cnpm i -S file-saver xlsx
cnpm i -D script-loader2、下载并引入Blob.js和Export2Excel.js
在src目录下创建excel文件,里面放入Blob.js 和Export2Excel.js两个文件（这两个文件可在文章底部获取）
下载地址：百度网盘 请输入提取码 提取码：ksnq
3、使用
<template><div><el-button type="primary" @click="export2Excel()">导出Excel</el-button></div>
</template><script>
export default {components: {},data() {return {tableData: [{ index: 0, username: "张三", password: 333, age: 22 },{ index: 1, username: "李四", password: 444, age: 23 }]};},props: {},created() {},mounted() {},computed: {},methods: {export2Excel() {require.ensure([], () => {const { export_json_to_excel } = require("@/excel/Export2Excel");const fieldName = ["索引", "用户名", "密码"];const filterVal = ["index", "username", "password"];const data = this.tableData.map(v => filterVal.map(j => v[j]));export_json_to_excel(fieldName, data, "用户列表");});}},watch: {}
};
</script><style lang="scss" scoped>
</style>| 参数 | 说明 | 类型 | 可选值 | 默认值 |
| header | 导出数据的表头 | Array | / | [] |
| data | 导出的具体数据 | Array | / | [] |
| filename | 导出文件名 | String | / | excel-list |
| autoWidth | 单元格是否要自适应宽度 | Boolean | true / false | true |
| bookType | 导出文件类型 | String | xlsx, csv, txt, more | xlsx |
4、效果图
基于此方法，封装的导出Excel组件：ExportExcel
首先还是引入依赖
cnpm i -S file-saver xlsx
cnpm i -D script-loader再下载Blob.js和Export2Excel.js，并在src目录下创建excel文件,里面放入Blob.js 和Export2Excel.js两个文件
下载地址：百度网盘 请输入提取码 提取码：ksnq
@/components/ExportExcel/index.vue：
<!--ExportExcel-->

</template><script>

};
</script><style lang="scss" scoped>
.ExportExcel {
}
</style>使用：
<template><div><ExportExcel:multipleSelection="multipleSelection":fieldName="exportExcelData.fieldName":fieldValue="exportExcelData.fieldValue"@exported="clearSelect()"></ExportExcel><el-table ref="ref_table"/></div>
</template>
<script>
import ExportExcel from "@/components/ExportExcel/index.vue";export default {components: {DialogSuppliers,ExportExcel,},data() {return {multipleSelection: [{"username":"admin","password":123},{"username":"test","password":1243}],exportExcelData: {fieldName: ["用户名", "密码"],fieldValue: ["username", "password"]}};},methods: {clearSelect() {this.$refs["ref_table"].clearSelection();}
}
</script>导出指定的记录
1、引入依赖
cnpm i -S file-saver xlsx
cnpm i -D script-loader2、使用
<template><div><el-button type="primary" @click="exportExcel">导出文件</el-button><el-table :data="tableData" style="width: 100%" id="out-table"><el-table-column prop="name" label="姓名" width="180"></el-table-column><el-table-column prop="age" label="年龄" width="80"></el-table-column><el-table-column prop="date" label="日期"></el-table-column></el-table></div>
</template><script>
//引入安装的依赖
import FileSaver from "file-saver";
import XLSX from "xlsx";
export default {data() {return {tableData: [{name: "张三",age: 22,date: "2016-05-02"},{name: "王小虎",age: 23,date: "2016-05-04"}]};},methods: {// XLSX.uitls.table_to_book( 放入的是table 的DOM 节点 ) ，sheetjs.xlsx 即为导出表格的名字，可修改！exportExcel() {let wb = XLSX.utils.table_to_book(document.querySelector("#out-table"));let wbout = XLSX.write(wb, {bookType: "xlsx",bookSST: true,type: "array"});FileSaver.saveAs(new Blob([wbout], { type: "application/octet-stream" }),"用户列表.xlsx");return wbout;}}
};
</script><style scoped>
