HTML表到Excel格式&扩展名不匹配

我有一个将HTML表转换为Excel文档的函数。但是,在打开文件时,我收到来自Excel的以下消息:

  

'something.xls'的文件格式和扩展名不匹配。等等...

以下是我用于导出的函数,它是来自this线程的@SamPopes答案的略微编辑版本。 obj参数是我使用table创建的document.createElement('table');元素。

是否有任何方法可以在打开文件时阻止此消息?

function export(obj) {
  var tab_text="<table border='2px'><tr>";
  var textRange; var j=0;
  tab = obj; //Table


  for(j = 0 ; j < tab.rows.length ; j++){     
    tab_text=tab_text+tab.rows[j].innerHTML+"</tr>";
    //tab_text=tab_text+"</tr>";
  }

  tab_text=tab_text+"</table>";
  tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, "");//remove if you want links in your table
  tab_text= tab_text.replace(/<img[^>]*>/gi,""); // remove if you want images in your table
  tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // removes input params

  var ua = window.navigator.userAgent;
  var msie = ua.indexOf("MSIE "); 

  if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer
    {
      txtArea1.document.open("txt/html","replace");
      txtArea1.document.write(tab_text);
      txtArea1.document.close();
      txtArea1.focus(); 
      sa=txtArea1.document.execCommand("SaveAs",true,"export.xls");
  } else { //other browser not tested on IE 11
      sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));            
      return (sa);
  }
}

正如我在上面的评论中所说,这是创建CSV文件的代码。这可以避免您收到的错误消息,但将消除您格式化数据的任何机会(据我所知)。这是我的代码,它使用一个进程用于IE,第二个用于所有其他浏览器:

function exportTotalDataFile(){
    var dataText = "";    
    var rowText = "";

    'allData is generated through an AJAX call that creates a JSON'
    'this loop creates the header row'
    for (var index in allData[0]) {
        rowText += index + ',';
    }

    'takes the trailing comma out, adds new row'
    rowText = rowText.slice(0, -1);
    dataText += rowText + '\r\n';

    'Produces the data rows'
    for (var i = 0; i < allData.length; i++) {
        var rowText = "";

        for (var index in allData[i]) {
            rowText += '"' + allData[i][index] + '",';
        }

        rowText.slice(0, rowText.length - 1);
        dataText += rowText + '\r\n';
    }

    var fileName = "Losses Report"; 

    'Internet Explorer logic'
    var isIE = false || !!document.documentMode;
    if (isIE){
        var IEwindow = window.open();
        IEwindow.document.write('sep=,\r\n' + dataText);
        IEwindow.document.close();
        IEwindow.document.execCommand('SaveAs', true, fileName + ".csv");
        IEwindow.close();
    } 
    'All the other browsers'
    else {
        var uri = 'data:text/csv;charset=utf-8,' + escape(dataText);
        var link = document.createElement("a");  
        link.href = uri;
        link.style = "visibility:hidden";
        link.download = fileName + ".csv";
        document.body.appendChild(link);
        link.click();
        document.body.removeChild(link);
    }

}

很抱歉,这种方法仅限于格式化部门,但我希望这会有所帮助
