, 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))
}
})()
tableToExcel('table', 'Table Title')

推荐答案
以下代码取表并将其转换为 excel 文件。
The following code takes the table and converts it to the excel file.
注意：该功能具有第三个参数作为文件名。
Note:- The function have 3rd parameter as the filename.
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, filename) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = {
worksheet: name || 'Worksheet',
table: table.innerHTML
}
document.getElementById("dlink").href = uri + base64(format(template, ctx));
document.getElementById("dlink").download = filename;
document.getElementById("dlink").click();
}
})()
<table id="newTab">
<th>Col 1</th>
<th>Col 2</th>
<th>Col 3</th>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
<tr>
<td>7</td>
<td>8</td>
<td>9</td>
</tr>
</table>
<a id="dlink" style="display:none;"></a>
<input type="button" onclick="tableToExcel('newTab', 'name', 'newSheet.xls')" value="Table to Excel">
打开下载的文件时可能会弹出以下错误。
The following Error might popup while opening the downloaded file.
打开文件时出错。但是，无论如何，点击是打开。
Error on opening the file. But it opens by clicking 'Yes' anyways.
文件打开成功。
