json数据导出excel

最近做的一个项目涉及到把数据导出到excel里面，网上找来找去，最终找到两种办法，废话不多说了

第一种:

拿到表格的id就可以抓取表格的数据，导出到excel，这种方式简单粗暴，引入这两个插件即可。

但是用这种方式会出现一种问题，就是当你的table有分页的情况下，这玩意只能抓取页面上的值，所以也不用多说了，其他分页的是导不出来的，值能导出当前分页的数据。

但是项目要求必须导出所有数据，这就出现了第二种解决方案，

使用起来也比较简单，拿到数据直接往里面塞就是了，最后调用方法。这样的话最终所有数据都出来了。

function JSONToExcelConvertor(JSONData, FileName, ShowLabel) {

var arrData = typeof JSONData != 'object' ? JSON.parse(JSONData) : JSONData;

var excel = '<table>';

//设置表头

var row = "<tr>";

for (var i = 0, l = ShowLabel.length; i < l; i++) {

row += "<td>" + ShowLabel[i].value + '</td>';

}

//换行

excel += row + "</tr>";

//设置数据

for (var i = 0; i < arrData.length; i++) {

var row = "<tr>";

for(var j=0;j<arrData[i].length;j++){

var value = arrData[i][j].value === "." ? "" : arrData[i][j].value;

row += '<td>' + value + '</td>';

}

excel += row + "</tr>";

}

excel += "</table>";

var excelFile = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:excel' xmlns='http://www.w3.org/TR/REC-html40'>";

excelFile += '<meta http-equiv="content-type" content="application/vnd.ms-excel; charset=UTF-8">';

excelFile += '<meta http-equiv="content-type" content="application/vnd.ms-excel';

excelFile += '; charset=UTF-8">';

excelFile += "<head>";

excelFile += "<!--[if gte mso 9]>";

excelFile += "<xml>";

excelFile += "<x:ExcelWorkbook>";

excelFile += "<x:ExcelWorksheets>";

excelFile += "<x:ExcelWorksheet>";

excelFile += "<x:Name>";

excelFile += "{worksheet}";

excelFile += "</x:Name>";

excelFile += "<x:WorksheetOptions>";

excelFile += "<x:DisplayGridlines/>";

excelFile += "</x:WorksheetOptions>";

excelFile += "</x:ExcelWorksheet>";

excelFile += "</x:ExcelWorksheets>";

excelFile += "</x:ExcelWorkbook>";

excelFile += "</xml>";

excelFile += "<![endif]-->";

excelFile += "</head>";

excelFile += "<body>";

excelFile += excel;

excelFile += "</body>";

excelFile += "</html>";

var uri = 'data:application/vnd.ms-excel;charset=utf-8,' + encodeURIComponent(excelFile);

var link = document.createElement("a");

link.href = uri;

link.style = "visibility:hidden";

link.download = FileName + ".xls";

document.body.appendChild(link);

link.click();

document.body.removeChild(link);

}
