Question

使用TCPDF打印pdf时遇到问题。故事板是，我有一个搜索表单，我将结果显示在表格中。我的目的是，当点击一个按钮时，用户可以在javascript中的window.open浏览器的新窗口中将此表打印成PDF。我使用ajax发送一些数据，在这种情况下，我发送包含<tbody></tbody>。现在，在ajax的成功，我不知道我应该怎么做。这是我的代码。

HTML

<tbody id="hasil-pencarian">
  <tr>
    <td>1</td>
    <td>TMS/IT/06/001</td>
    <td>Erika Julia Widiyanti</td>
    <td>Marketing</td>
    <td>14-06-2015 13:59</td>
    <td>14-06-2015 14:00</td>
    <td>Erika test 1</td>
    <td>Jawab erika request 1<br></td>
    <td>14-06-2015 15:00</td>
    <td>15-06-2015 17:19</td>
    <td class="center" width="10px">
       <a class="btn btn-success"><i class="halflings-icon white print" id="print"></i>Print</a>
   </td>
  </tr>

<p class="center">
  <button class="btn btn-small btn-primary" id="print-bottom">Print Data Di atas</button>
</p>

这是jquery上的ajax

$(document).on('click', '#print-bottom', function() {
var result = $("#hasil-pencarian").html();
    $.ajax({
        url: '<?php echo base_url() . 'it_team/control_it/generate_pdf' ?>',
            type: 'POST',
            data: {result: result},
            success: function() {
                //it still gives me a blank content of table if I use like this :
                window.open("<?php echo base_url() . 'it_team/control_it/generate_pdf/' ?>", "_blank", "top=25, left=250, toolbar=no, width=1000, height=600"); 
            },
            error: function() {
                alert('Error');
            }
    });
 });

这是TCPDF

public function generate_pdf() {
    if (($this->session->userdata('logged_in') != "logging") && ($this->session->userdata('logged_in') != "IT")) {
        redirect('control_auth');
    } else {
        $this->load->library("tcpdf");
        //Post from ajax
        $html = $this->input->post('result');

        $pdf = new tcpdf(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
        $pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
        $pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
        $pdf->AddPage();
        $pdf->SetFont('helvetica', '', 8);

        // This is for <th> header
        $tbl = <<<EOD
        <table cellspacing="0" cellpadding="1" border="1">
          <tr>
           <td align="center" width='1px'><b> No.  </b></td>
           <td align="center"><b>No_Req</b></td>
           <td align="center"><b>Nama user</b></td>
           <td align="center"><b>Dept</b></td>                                            
           <td align="center"><b>Masuk ke IT</b></td>
           <td align="center"><b>Diterima IT</b></td>
           <td align="center"><b>Keluhan</b></td>
           <td align="center"><b>Tindakan IT</b></td>
           <td align="center"><b>Estimasi</b></td>
           <td align="center"><b>Tutup Request</b></td>
         </tr>

      EOD;

        // Adding the content of table based from post ajax
        $tbl = $tbl. $html;
        $tbl = $tbl . "</table>";
        $pdf->writeHTML($tbl, true, false, false, false, '');
        $pdf->Output('example_048.pdf', 'I');
    }
}

在ajax成功仍然空白页面中使用TCPDF打印pdf
