Exporting HTML tables to Excel (.xls) in a separate sheet
提问by Atanas Bozhkov
I've got a simple HTML page (generated by an external application) that contains a table view. I am trying to scrape off the tables from the page and put them in an Excel workbook. I have managed to put the whole HTML contents in a workbook by using the method available here.
我有一个包含表视图的简单 HTML 页面（由外部应用程序生成）。我试图从页面上刮下表格并将它们放入 Excel 工作簿中。通过使用此处提供的方法，我已设法将整个 HTML 内容放入工作簿中。
Code from the related question:
来自相关问题的代码：
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<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"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
, base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))
}
})()
The method however does not support multiple spreadsheets. What I need is for every HTML table being in it's own SpreadSheet in the same Excel workbook. Something like this:
然而，该方法不支持多个电子表格。我需要的是每个 HTML 表都在同一个 Excel 工作簿中它自己的电子表格中。像这样的东西：
I have tried to create a sample Excel document with two spreadsheets and then reverse engineer it by looking at an export in .html format. Unfortunately I failed to understand how to recreate the connection betwee a workbook and it's sheets.
我尝试使用两个电子表格创建一个示例 Excel 文档，然后通过查看 .html 格式的导出对其进行逆向工程。不幸的是，我无法理解如何在工作簿和工作表之间重新创建连接。
As far as I can understand the format()function does the 'magical' combining of the worksheet data and the Excel template. The function looks very cryptic to me, so I have no idea how to go about modifying it.
据我所知，该format()函数对工作表数据和 Excel 模板进行了“神奇”的组合。这个函数对我来说看起来很神秘，所以我不知道如何修改它。
What I need as an end game is having the possibility to call something like.
tableToExcel(document.getElementsByTagName('table'), 'Workbook Name');
作为最终游戏，我需要的是有可能调用类似的东西。
tableToExcel(document.getElementsByTagName('table'), 'Workbook Name');
Any ideas if this is at all possible, and if so - how to go about making it happen?
如果这是可能的，任何想法，如果是的话 - 如何去实现它？

$(document).ready(function() {
$("#btnExport").click(function(e) {
//getting values of current time for generating the file name
var dt = new Date();
var day = dt.getDate();
var month = dt.getMonth() + 1;
var year = dt.getFullYear();
var hour = dt.getHours();
var mins = dt.getMinutes();
var postfix = day + "." + month + "." + year + "_" + hour + "." + mins;
//creating a temporary HTML link element (they support setting file names)
var a = document.createElement('a');
//getting data from our div that contains the HTML table
var data_type = 'data:application/vnd.ms-excel';
var table_div = document.getElementById('dvData');
var table_html = table_div.outerHTML.replace(/ /g, '%20');
a.href = data_type + ', ' + table_html;
//setting the file name
a.download = 'exported_table_' + postfix + '.xls';
//triggering the function
a.click();
//just in case, prevent default behaviour
e.preventDefault();
});
});
