我正在尝试将多个 html 表格导出到单个文件 excel (xls)
应该是这样
Thanks Credit : How do I export multiple html tables to excel?
HTML代码
<html>
<head>
<title>JS to Excel</title>
</head>
<body>
<table id="1">
<tr><td>Hi</td></tr>
<tr><td>Hey</td></tr>
<tr><td>Hello</td></tr>
</table>
<table id="2">
<tr><td>Night</td></tr>
<tr><td>Evening</td></tr>
<tr><td>Nite</td></tr>
</table>
<a id="dlink" style="display:none;"></a>
<input type="button" onclick="tablesToExcel(['1', '2'], ['first', 'second'], 'myfile.xls')" value="Export to Excel">
<script src="~/Views/JS/JSExcel.js" type="text/javascript"></script>
</body>
像这样的 Javascript
var tablesToExcel = (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>'
, templateend = '</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head>'
, body = '<body>'
, tablevar = '<table>{table'
, tablevarend = '}</table>'
, bodyend = '</body></html>'
, worksheet = '<x:ExcelWorksheet><x:Name>'
, worksheetend = '</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>'
, worksheetvar = '{worksheet'
, worksheetvarend = '}'
, base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
, wstemplate = ''
, tabletemplate = '';
return function (table, name, filename) {
var tables = table;
for (var i = 0; i < tables.length; ++i) {
wstemplate += worksheet + worksheetvar + i + worksheetvarend + worksheetend;
tabletemplate += tablevar + i + tablevarend;
}
var allTemplate = template + wstemplate + templateend;
var allWorksheet = body + tabletemplate + bodyend;
var allOfIt = allTemplate + allWorksheet;
var ctx = {};
for (var j = 0; j < tables.length; ++j) {
ctx['worksheet' + j] = name[j];
}
for (var k = 0; k < tables.length; ++k) {
var exceltable;
if (!tables[k].nodeType) exceltable = document.getElementById(tables[k]);
ctx['table' + k] = exceltable.innerHTML;
}
//document.getElementById("dlink").href = uri + base64(format(template, ctx));
//document.getElementById("dlink").download = filename;
//document.getElementById("dlink").click();
window.location.href = uri + base64(format(allOfIt, ctx));
}
})();
它在一个 excel 文件 (xls) 中处理 2 个表
我的问题是，如果我有 1000 个表怎么办？
我如何使用 DO 或 for 循环来解决我的问题？
我是一名学生，是编程新手，谢谢
