How do i add javascript in TCPDF?

[sashavalentina]

As i can't use css to make my auto numbering for my tables with css using TCPDF.I'm trying to use Javascipt to make this work. I read the documentation this and this on how to add javascript into my tcpdf. But i do not know why it does not work and it shows the error of Parse error: syntax error, unexpected 'var' (T_VAR) in C:\filepath\XAMPP\htdocs\filepath\customerinvoice.php on line 211 Can i know how can i define my 'var' in tcpdf? Or is not possible to add javascript in TCPDF? Please help me with this issue. Any help will be apprecialted. Thanks in advance 

This are my codes

 

   $htmlcontent .='
<table cellpadding="7" style="max-height: 1000px;">
    <tr class="receiptcontent">
    <td style="font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">

    </td>

        <td width= "30%" colspan="3" style="font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">
            '.$irow['product_name'].'
        </td>
        
         <td style=" font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">
           '.$irow['product_code'].'
        </td>
         <td width= "15%" style=" font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">
           '.$irow['quantity'].' '.$irow['quantity_unit'].'
        </td>
         <td  width= "15%" style=" font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">
          RM '.$irow['original_price'].'
        </td>
        <td  width= "20%" style=" font-weight: normal;font-size: 12px;line-height: 17px;color: #000000;">
            RM '.$irow['price'].'
        </td>
    </tr>
</table>

';
}

This is the javascript i added in to implement auto numbering for my tables

 

$js = 
var table = document.getElementsByTagName('table')[0],
  rows = table.getElementsByTagName('tr'),
  text = 'textContent' in document ? 'textContent' : 'innerText';

for (var i = 0, len = rows.length; i < len; i++) {
  rows[i].children[0][text] = i + ': ' + rows[i].children[0][text];
};
    
// Add Javascript code
$pdf->IncludeJS($js);
    $pdf->writeHTML($htmlcontent);  
    ob_end_clean(); 
    $pdf->Output('customerinvoice.pdf', 'I');

If only PHP had a way you could increment a count.

$i = 0;  
$content = '
    <style>
    td {
        font-weight: normal;
        font-size: 8px;
        line-height: 12px;
        color: #000000;
    }
    </style>
    
    <table id="receiptTable" style="max-height: 1000px;" >
        <tr>
         <td width = "7%" >
            '. ++$i .'  
            </td>
        
            <td  width= "8%"  >
                '.'xxxxxx'.'
