篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了前端表格下载/打印(可vue/可element-ui)相关的知识,希望对你有一定的参考价值。
1.装依赖
npm install xlsx --save
npm install file-saver --save
2.组件中引入
import FileSaver from ‘file-saver‘ import XLSX from ‘xlsx‘
3.下载表格
//导出Excel
exportToExcel () {
let et = XLSX.utils.table_to_book(document.querySelector(‘#myTable‘)); //此处传入table的DOM节点
console.log(11,et);
let etout = XLSX.write(et, {
bookType: ‘xlsx‘,
bookSST: true,
type: ‘array‘
});
try {
FileSaver.saveAs(new Blob([etout], {
type: ‘application/octet-stream‘
}), ‘trade-publish.xlsx‘); //trade-publish.xlsx 为导出的文件名
} catch (e) {
console.log(e, etout) ;
}
return etout;
},
4.打印表格
//打印页面内容
printContent(){
console.log(11);
let wpt = document.querySelector(‘#myTable‘);
let newContent = wpt.innerhtml;
let oldContent = document.body.innerHTML;
document.body.innerHTML = newContent;
window.print(); //打印方法
// window.localtion.reload();
history.go(0)
document.body.innerHTML = oldContent;
}
5.整体demo
<template> <div class="myPage"> <el-button @click="exportToExcel">下载表格</el-button> <el-button @click="printContent">打印表格</el-button> <div class="myTable"> <el-table id="myTable" :height="tableHeight" :data="tableData" style="width: 100%"> <el-table-column prop="date" label="日期" width="180"> </el-table-column> <el-table-column prop="name" label="姓名" width="180"> </el-table-column> <el-table-column prop="address" label="地址"> </el-table-column> </el-table> </div> </div> </template> <script> import FileSaver from ‘file-saver‘ import XLSX from ‘xlsx‘ export default { data (){ return { tableData: [ { date: ‘2016-05-02‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1518 弄‘ }, { date: ‘2016-05-04‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1517 弄‘ }, { date: ‘2016-05-01‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1519 弄‘ }, { date: ‘2016-05-03‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1516 弄‘ }, { date: ‘2016-05-02‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1518 弄‘ }, { date: ‘2016-05-04‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1517 弄‘ }, { date: ‘2016-05-01‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1519 弄‘ }, { date: ‘2016-05-03‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1516 弄‘ }, { date: ‘2016-05-02‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1518 弄‘ }, { date: ‘2016-05-04‘, name: ‘王小虎‘, address: ‘上海市普陀区金沙江路 1517 弄‘ } ], tableTitleData: [ { label: ‘日期‘, prop: ‘date‘ }, { label: ‘姓名‘, prop: ‘name‘ }, { label: ‘地址‘, prop: ‘address‘ } ], tableHeight:‘auto‘, }; }, methods:{ //导出Excel exportToExcel () { let et = XLSX.utils.table_to_book(document.querySelector(‘#myTable‘)); //此处传入table的DOM节点 console.log(11,et); let etout = XLSX.write(et, { bookType: ‘xlsx‘, bookSST: true, type: ‘array‘ }); try { FileSaver.saveAs(new Blob([etout], { type: ‘application/octet-stream‘ }), ‘trade-publish.xlsx‘); //trade-publish.xlsx 为导出的文件名 } catch (e) { console.log(e, etout) ; } return etout; }, //打印页面内容 printContent(){ console.log(11); let wpt = document.querySelector(‘#myTable‘); let newContent = wpt.innerHTML; let oldContent = document.body.innerHTML; document.body.innerHTML = newContent; window.print(); //打印方法 // window.localtion.reload(); history.go(0) document.body.innerHTML = oldContent; }, }, mounted(){}, } </script> <style lang=‘less‘ scoped> .myPage{ overflow-y: scroll; } .myTable{ width: 800px; } </style>
