I just little bit specify my question. What is the best way how to add jquery code by joomla plugin?

Is this the best way? And how can I choose that these code should be applied just for chceckout page?

Thank you

Code Select Expand

<?php

// no direct access
defined('_JEXEC') or die;

class plgContentHelloworld extends JPlugin
{
    public function onAfterRender() {
        echo '<script>';
            echo 'alert("Hello World!");';
        echo '</script>';
        }
}

?>

detect what page your on ..

e.g.

Code Select Expand

$jinput = JFactory::getApplication()->input;
$option = $jinput->get('option');
$view = $jinput->get('view');
$task = $jinput->get('task');
if ($option == 'com_virtuemart' && $view == 'cart') {
echo 'blah';

}
