 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))
    }
})()

以下代码将表格转换为 excel 文件。

注意： - 该函数有第三个参数作为文件名。

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。

打开文件时出错。但无论如何都会点击“是”打开它。

文件成功打开。

有没有办法在js生成的excel文件上设置安全内容？
