无法将表导出到CSV

Question

I want to fill a table and export it to csv. 我想填一张表并将其导出到csv。 The following is my code 以下是我的代码

<html>
<head>
    <title></title>
</head>
<body>


<div class="container">
    <h1>Build Table</h1>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

    <div>
        <table id="blacklistgrid">
            <tr id="Row1">
                <td>Week Number</td>
                <td>Oranges Sold</td>
                <td>Apples Sold</td>
            </tr>
            <tr class="Row2">
                <td>
                    <input type="text"/>
                </td>
                <td>
                    <input type="text"/>
                </td>
                <td>
                    <input type="text"/>
                </td>
            </tr>
        </table>
        <button type="button" id="btnAdd">Add Row!</button>
        <button><a href="#" class="export">Export Table data into Excel</a></button>
    </div>

    <script>
     jQuery(document).ready(function () {
     jQuery('#btnAdd').click(function () {
          jQuery( ".Row2" ).clone().appendTo( "#blacklistgrid" );

        });
     });


$(document).ready(function() {

  function exportTableToCSV($table, filename) {

    var $rows = $table.find('tr:has(td)'),

      // Temporary delimiter characters unlikely to be typed by keyboard
      // This is to avoid accidentally splitting the actual contents
      tmpColDelim = String.fromCharCode(11), // vertical tab character
      tmpRowDelim = String.fromCharCode(0), // null character

      // actual delimiter characters for CSV format
      colDelim = '","',
      rowDelim = '"\r\n"',

      // Grab text from table into CSV formatted string
      csv = '"' + $rows.map(function(i, row) {
        var $row = $(row),
          $cols = $row.find('td');

        return $cols.map(function(j, col) {
          var $col = $(col),
            text = $col.text();

          return text.replace(/"/g, '""'); // escape double quotes

        }).get().join(tmpColDelim);

      }).get().join(tmpRowDelim)
      .split(tmpRowDelim).join(rowDelim)
      .split(tmpColDelim).join(colDelim) + '"';

    // Deliberate 'false', see comment below
    if (false && window.navigator.msSaveBlob) {

      var blob = new Blob([decodeURIComponent(csv)], {
        type: 'text/csv;charset=utf8'
      });

      // Crashes in IE 10, IE 11 and Microsoft Edge
      // See MS Edge Issue #10396033
      // Hence, the deliberate 'false'
      // This is here just for completeness
      // Remove the 'false' at your own risk
      window.navigator.msSaveBlob(blob, filename);

    } else if (window.Blob && window.URL) {
      // HTML5 Blob
      var blob = new Blob([csv], {
        type: 'text/csv;charset=utf-8'
      });
      var csvUrl = URL.createObjectURL(blob);

      $(this)
        .attr({
          'download': filename,
          'href': csvUrl
        });
    } else {
      // Data URI
      var csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

      $(this)
        .attr({
          'download': filename,
          'href': csvData,
          'target': '_blank'
        });
    }
  }

  // This must be a hyperlink
  $(".export").on('click', function(event) {
    // CSV
    var args = [$('#blacklistgrid'), 'export.csv'];

    exportTableToCSV.apply(this, args);

    // If CSV, don't do event.preventDefault() or return false
    // We actually need this to be a typical hyperlink
  });
});


    </script>

</body>
</html>

I can fill the table and add rows dynamically. 我可以填写表格并动态添加行。 However, I can not seem to export the filled data to the csv file. 但是，我似乎无法将已填充的数据导出到csv文件。 What am I doing wrong? 我究竟做错了什么？

Since you are using input elements, the text() method won't work - essentially there is nothing between your <td> elements. 由于您正在使用输入元素，因此text()方法将不起作用-实际上<td>元素之间没有任何内容。 Instead, you want to use the val() method to get the text from said input element. 相反，您想使用val()方法从所述输入元素获取文本。 Here's a quick-and-dirty example: https://jsfiddle.net/dzy5ktv6/ 这是一个简单的例子： https : //jsfiddle.net/dzy5ktv6/

Note that I changed the selector to select input elements instead of td . 请注意，我将选择器更改为选择input元素，而不是td 。
