1 安装依赖
npm install xlsx
npm install file-saver
2 创建exportExcel.js文件
import fs from 'file-saver'
import * as XLSX from 'xlsx'
export function exportExcel(json, fields, filename = '.xlsx') {//导出xlsx
json.forEach(item => {
for (let i in item) {
if (fields.hasOwnProperty(i)) {
item[fields[i]] = item[i];
}
delete item[i]; //删除原先的对象属性
}
})
let sheetName = filename //excel的文件名称
let wb = XLSX.utils.book_new() //工作簿对象包含一SheetNames数组,以及一个表对象映射表名称到表对象。XLSX.utils.book_new实用函数创建一个新的工作簿对象。
let ws = XLSX.utils.json_to_sheet(json, { header: Object.values(fields) }) //将JS对象数组转换为工作表。
wb.SheetNames.push(sheetName)
wb.Sheets[sheetName] = ws
const defaultCellStyle = { font: { name: "Verdana", sz: 13, color: "FF00FF88" }, fill: { fgColor: { rgb: "FFFFAA00" } } };//设置表格的样式
let wopts = { bookType: 'xlsx', bookSST: false, type: 'binary', cellStyles: true, defaultCellStyle: defaultCellStyle, showGridLines: false } //写入的样式
let wbout = XLSX.write(wb, wopts)
let blob = new Blob([s2ab(wbout)], { type: 'application/octet-stream' })
fs.saveAs(blob, filename + '.xlsx')
}
const s2ab = s => {
var buf;
if (typeof ArrayBuffer !== 'undefined') {
buf = new ArrayBuffer(s.length)
var view = new Uint8Array(buf)
for (var i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xff
return buf
} else {
buf = new Array(s.length);
for (var i = 0; i != s.length; ++i) buf[i] = s.charCodeAt(i) & 0xFF;
return buf;
}
}
3 使用
(1)在需要导出文件页面引入exportExcel方法
(2)使用时调用方法,确保列表字段与数据字段一致
