Question

这是一个将HTML表格转换为xlsx的简单代码。导出的文件带有xlsx扩展名，但是当我尝试打开文件时出现错误＆＃34; Excel无法打开文件，因为文件格式或文件扩展名无效。＆＃34;

我无法解决此问题。将HTML导出为.xlsx文件是必需的。我如何解决这个问题，或者有没有更好的方法可以不使用第三方JavaScript。

我的代码

的Javascript

 <script>
      var isIE = /*@cc_on!@*/false || !!document.documentMode;
      function ExportToExcel(ExTable){
           tableToExcel(ExTable,"XDK");
      }
      var tableToExcel = (function() {
           var uri = 'data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8;filename=XDK_Export;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 $.base64.encode(s)
           } 
           , format = function(s, c) {
                return s.replace(/{(\w+)}/g, function(m, p) {
                     return c[p];
                })
           }
           return function(table) {
                var objHtmlD = $("#"+table).find(".DtlTableContainer").clone()
                $(objHtmlD).find("a").each(function(index){
                     $(this).replaceWith($(this).text())
                });
                if (!table.nodeType) 
                     table = $("#"+table).find(".HdrTableContainer").html() + $(objHtmlD).html()
                var ctx = {
                     worksheet: name || 'Worksheet',
                     table: table
                }
                var sa;
                if(isIE)
                {
                     var ifrm = document.createElement('iframe');
                     ifrm.id = "txtExport";
                     ifrm.style.display = 'none';
                     document.body.appendChild(ifrm);
                     txtExport.document.open("txt/html","replace");
                     txtExport.document.write(format(template, ctx));
                     txtExport.document.close();
                     txtExport.focus();
                     sa= txtExport.document.execCommand("SaveAs",true,"XDK_Export.xlsx");
                     ifrm.parentNode.removeChild(ifrm);
                }
                else
                     sa = window.open(uri + base64(format(template, ctx)),"XDK_Export.xlsx");
                return sa;
           }
      })()
 </script>

有了这个，我也在使用jquery.base64.js
