สอบถามเรื่องการสั่งพิมพ์รายงานจาก fpdf ครับ

var $javascript;
var $n_js;

function IncludeJS($script) {
    $this->javascript = $script;
}

function putJavascript() {
    $this->_newobj();
    $this->n_js = $this->n;
    $this->_out('<<');
    $this->_out('/Names [(EmbeddedJS) ' . ($this->n + 1) . ' 0 R]');
    $this->_out('>>');
    $this->_out('endobj');
    $this->_newobj();
    $this->_out('<<');
    $this->_out('/S /JavaScript');
    $this->_out('/JS ' . $this->_textstring($this->javascript));
    $this->_out('>>');
    $this->_out('endobj');
}

function putResources() {
    parent::_putresources();
    if (!empty($this->javascript)) {
        $this->_putjavascript();
    }
}

function putCatalog() {
    parent::_putcatalog();
    if (!empty($this->javascript)) {
        $this->_out('/Names <</JavaScript ' . ($this->n_js) . ' 0 R>>');
    }
}

$mypdf->IncludeJS("print('true');");
$mypdf->Output('mypdf.pdf', 'I');
