How do i add javascript in TCPDF?

Question

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 .='

    
    

    

        
            '.$irow['product_name'].'
        
        
         
           '.$irow['product_code'].'
        
         
           '.$irow['quantity'].' '.$irow['quantity_unit'].'
        
         
          RM '.$irow['original_price'].'
        
        
            RM '.$irow['price'].'
        
    


';
}

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');

Please enclose the js statements in double quotations:

Change

$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];
};

to

$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];
};
