vue+table2excel 导出JSON数据到excle

最近在做一个信息采集管理系统,需要把采集到的信息导出到excle,先说说在vue中安装和引入table2excel  

//安装
npm install js-table2excel

//引入
import table2excel from 'js-table2excel'

 

采集系统需要收集的信息包含姓名、手机号、身份证号、还有一项是上传图片;

模拟数据如下:

const data=[
    {
        name:"张三",
        phone:"13512345678",
        idCard:"412356198601251234",
        image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
    },
    {
        name:"李四",
        phone:"13612345678",
        idCard:"412356198601251234",
        image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
    },
    {
        name:"王五",
        phone:"13712345678",
        idCard:"412356198601251234",
        image:"https://profile.csdnimg.cn/9/8/3/2_xiaoxiaojie12321"
    }
]

需求是导出时将图片一块导出 

下面是导出按钮上绑定的方法

exportExcel() {

      const column=[
        {
          title: '姓名',
          key: 'name',
          type: 'text'
        },
        {
          title: '手机号',
          key: 'phone',
          type: 'text'
        },
        {
          title: '身份证号',
          key: 'idCard',
          type: 'text'
        },
        {
          title: '图片',
          key: 'image',
          type: 'image',
          width: 80,
          height: 50
        },
      ]

      /** column数据的说明 */
      // 1.title为列名
      // 2.key为data数据每个对象对应的key
      // 3.若为图片格式, 需要加type为image的说明,并且可以设置图片的宽高
      const data = this.tableData
      const excelName = `人员信息统计表`
      table2excel(column, data, excelName)
}

本人亲测,这样确实可以导出数据中的图片,但是又出现了一个新问题,导出表格内的身份证号码显示成了科学计数法,这肯定不符合要求,找了半天的资料,也没找到一个合适的案例,后面收到网友提供的方法启发,才解决;

网友提供的方法如下:

只需在td上加上如下style, 

style="mso-number-format:'\@';" ng-bind="data.paySerialNo">

可是我想了半天,我是通过JSON数据导出的,我改吧这个代码加到哪儿;无奈之下准备去看看依赖代码:

源码文件路径  :node_modules\js-table2excel\index.js

下面是我修改后的代码

/* eslint-disable */
let idTmr;
const getExplorer = () => {
	let explorer = window.navigator.userAgent;
	//ie
	if (explorer.indexOf("MSIE") >= 0) {
		return 'ie';
	}
	//firefox

	else if (explorer.indexOf("Firefox") >= 0) {
		return 'Firefox';
	}
	//Chrome
	else if (explorer.indexOf("Chrome") >= 0) {
		return 'Chrome';
	}
	//Opera
	else if (explorer.indexOf("Opera") >= 0) {
		return 'Opera';
	}
	//Safari
	else if (explorer.indexOf("Safari") >= 0) {
		return 'Safari';
	}
}
// 判断浏览器是否为IE
const exportToExcel = (data, name) => {

	// 判断是否为IE
	if (getExplorer() == 'ie') {
		tableToIE(data, name)
	} else {
		tableToNotIE(data, name)
	}
}

const Cleanup = () => {
	window.clearInterval(idTmr);
}

// ie浏览器下执行
const tableToIE = (data, name) => {
	let curTbl = data;
	let oXL = new ActiveXObject("Excel.Application");

	//创建AX对象excel
	let oWB = oXL.Workbooks.Add();
	//获取workbook对象
	let xlsheet = oWB.Worksheets(1);
	//激活当前sheet
	let sel = document.body.createTextRange();
	sel.moveToElementText(curTbl);
	//把表格中的内容移到TextRange中
	sel.select;
	//全选TextRange中内容
	sel.execCommand("Copy");
	//复制TextRange中内容
	xlsheet.Paste();
	//粘贴到活动的EXCEL中

	oXL.Visible = true;
	//设置excel可见属性

	try {
		let fname = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
	} catch (e) {
		print("Nested catch caught " + e);
	} finally {
		oWB.SaveAs(fname);

		oWB.Close(savechanges = false);
		//xls.visible = false;
		oXL.Quit();
		oXL = null;
		// 结束excel进程,退出完成
		window.setInterval("Cleanup();", 1);
		idTmr = window.setInterval("Cleanup();", 1);
	}
}

// 非ie浏览器下执行
const tableToNotIE = (function () {
	// 编码要用utf-8不然默认gbk会出现中文乱码
	const uri = 'data:application/vnd.ms-excel;base64,',
		template = '{table}
'; const base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))); } const format = (s, c) => { return s.replace(/{(\w+)}/g, (m, p) => { return c[p]; }) } return (table, name) => { const ctx = { worksheet: name, table } const url = uri + base64(format(template, ctx)); if (navigator.userAgent.indexOf("Firefox") > -1){ window.location.href = url } else { const aLink = document.createElement('a'); aLink.href = url; aLink.download = name || ''; let event; if (window.MouseEvent) { event = new MouseEvent('click'); } else { event = document.createEvent('MouseEvents'); event.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null); } aLink.dispatchEvent(event); } } })() // 导出函数 const table2excel = (column, data, excelName) => { const typeMap = { image: getImageHtml, text: getTextHtml } let thead = column.reduce((result, item) => { result += `${item.title}` return result }, '') thead = `${thead}` let tbody = data.reduce((result, row) => { const temp = column.reduce((tds, col) => { tds += typeMap[col.type || 'text'](row[col.key], col) return tds }, '') result += `${temp}` return result }, '') tbody = `${tbody}` const table = thead + tbody // 导出表格 exportToExcel(table, excelName) function getTextHtml(val) { //在此处生成单元格时添加上述样式属性 return `${val}` } function getImageHtml(val, options) { options = Object.assign({width: 40, height: 60}, options) return `` } } export default table2excel

好嘞,搞完这个就结束了
