TCPDF不会在ajax调用下生成PDF文件

问题描述

我正在尝试使用php的TCPDF库生成和下载pdf文件。我使用javascript将参数传递给php到ajax：这些参数来自html表，我将其作为数组传输到PHP：这是我的Javascript代码的一部分：

I am trying to generate and download pdf file using the library TCPDF of php. I pass the parameters to php thru ajax using javascript: These parameters comes from html table, that I transfer to the PHP as an array :Here is the portion of my Javascript code:

var myTableArray = [];
    var nb = 0;

$("table#Table tr").each(function() {
    var arrayOfThisRow = [];
    var tableData = $(this).find('td');
    if (tableData.length > 0) {
        tableData.each(function() { arrayOfThisRow.push($(this).text()); });
        myTableArray.push(arrayOfThisRow);
        nb = nb +1;
    }
});

    jQuery.ajax({
         type: "post",
         url: "Generate_PDF.php",
         data: {table:myTableArray, Line :nb },
         success: function(count){
             alert("done");
         }
    }); 

这里是PHP代码：

And here is the PHP Code:

function fetch_data()
 {
$aDataTableDetailHTML = ' ';
     $count = $_POST['Line'];
      $line = 0;
      $row = 0;
      for($line; $line < $count; $line++)
      {
          for ($row =0; $row < 2; $row++)
          {
             If ($row == 0)
                {
    $aDataTableDetailHTML .= '<tr><td>'.$_POST['table'][$line][$row].'</td>';
                } enter code here
                else
                {
    $aDataTableDetailHTML .= '<td>'.$_POST['table'][$line][$row].'</td></tr>';
                }
          }
      }
      $aDataTableDetailHTML1 = '<tr><td> introduction 123 </td><td> temps zero</td></tr>';
    return $aDataTableDetailHTML;

- > Network-> preiew我看到pdf文件的确如此没有生成，我看到一个奇怪的长文本开头：

in the chrome consol ->Network->preiew I see that the pdf file does not get generated, and I see a strange long text that starts with:

%PDF-1.7
%âãÏÓ
7 0 obj
<< /Type /Page /Parent 1 0 R /LastModified (D:20170513141422+02'00') /Resources 2 0 R

这个奇怪的文字太长了它结束了with：

This strange text is too long and it ends with:

0000006871 00000 n
trailer
<< /Size 12 /Root 11 0 R /Info 9 0 R /ID [ <f7adf2ceab2607d2e2cecc277437d8cd> <f7adf2ceab2607d2e2cecc277437d8cd> ] >>
