最近在做项目,前端进行处理数据,导出excel中,还是遇到不少问题,这里将其进行总结一下,博主是vue框架开发,借用file-saver和xlsx插件进行导出excel,我们来看下代码和效果。地址链接如下:https://www.npmjs.com/package/js-xlsx
博主自己封装了一个方法xlsx.js,然后在vue中进行调用就行,如下:
import fs from \'file-saver\' import XLSX from \'xlsx\' export default (json, fields, filename = \'测试数据.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 => { if (typeof ArrayBuffer !== \'undefined\') { var 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 { var buf = new Array(s.length); for (var i = 0; i != s.length; ++i) buf[i] = s.charCodeAt(i) & 0xFF; return buf; } }
