Answer 1

Another option is to make a shortcode. In this example, the shortcode will only be printed if it contains the attributes x and y, e.g.: [myscript x="10" y="20"]. I'm using a simple script that shows a JS alert dialog with the attributes values.

add_shortcode( 'myscript', 'sample_shortcode_so_6195635' );

function sample_shortcode_so_6195635( $atts, $content = null )
{   
    if( isset( $atts['x'] ) && isset( $atts['y'] ) )
    {
        $x = $atts['x'];
        $y = $atts['y'];

        // See: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc
        $html = <<Show Shortcode Atts

           
HTML;
        return $html;
    }
}
