在单独的工作表中将HTML表导出到Excel（.xls） [英] Exporting HTML tables to Excel (.xls) in a separate sheet
问题描述
我有一个简单的HTML页面（由外部应用程序生成），它包含一个表视图。
我试图从页面中删除表，并将它们放在Excel工作簿中。
我已经设法通过使用可用的方法将整个HTML内容放在工作簿中
$（document）.ready（function（）{
$（＃btnExport）点击（function（e）{
//获取生成文件名的当前时间值
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 +。+ + + + +++++小时++ mins;
//创建一个临时HTML链接元素（支持设置文件名）
var a = document.c reateElement（ A）;
//从我们的div获取包含HTML表的数据
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;
//设置文件名
a.download ='exported_table_'+ postfix +'.xls';
//触发函数
a.click（）;
//以防万一，防止默认行为
e.preventDefault（）;
}）;
}）;

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.
Code from the related question:
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:
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.
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.
What I need as an end game is having the possibility to call something like.
tableToExcel(document.getElementsByTagName('table'), 'Workbook Name');
Any ideas if this is at all possible, and if so - how to go about making it happen?

$(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();
});
});
