使用Django导出动态表数据

Question

我有一个由屏幕抓屏代码生成的表格，该表格运行良好。我还向该表添加了过滤器（搜索栏，下拉列表和显示条目限制）。此外，我刚刚添加了一个导出按钮，当单击并将所有表数据传输到csv时，该按钮将起作用。唯一的缺点是，即使启用了过滤器，导出按钮也将导出整个表。例如，如果我将下拉列表设置为仅在表格中显示男性，并将结果限制为每页10个，则“导出”按钮将仅导出整个表格。

我在这里搜索了一段时间，但没有找到解决方法。发送帮助。

这是我的html

    tmpColDelim = String.fromCharCode(11), r

    csv = '"' + $rows.map(function(i, row) {

          text = $col.text();

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

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

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

  if (false && window.navigator.msSaveBlob) {

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

    window.navigator.msSaveBlob(blob, filename);

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

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

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

$(".export").on('click', function(event) {
  // CSV
  var args = [$('#Data>table'), 'export.csv'];

  exportTableToCSV.apply(this, args);

});
});
</script>

我希望导出按钮能够与已经安装的过滤器一起很好地工作。
