尝试

$body .= '<select name="number" id="'.$row["ID"] .'" onchange="changeNumber( this );" >';
        $qty = (int) $row["quantity"];
        for ($number = 0; $number <= 10; $number++) {
            $selected = '';
            if($number == $qty) {
                $selected = "selected";
            }
            $body .= '<option '.$selected.' value="' . $number . '">' . $number . '</option>';
        }
        $body .= '</select>';
