jquery: How do I add a class to the td holding my input field?

Hi,

I am trying to add a class to the <td> that is holding my span and input field but I can only seem to add the class to the span tag that is holding the input field.

the form is like this:
<td><span><Input/></span></td>

I am using Jquery, please modify the code below.

Thanks.
$(document).ready(function(){
$(".orderQty span INPUT").change(function(){
  
         if($(this).val() > 0 ) {
         
           $(this).parent().addClass("selected");
           
        
        } else {
            $(this).parent().removeClass("selected");
        }
});

<td class="orderQty"><span dir="none">
<input name="ctl00$m$g_7279058e_e51a_4bdc_bae0_cf09ae6c9811$ff10_1$ctl00$ctl00$TextField" type="text" value="0" id="ctl00_m_g_7279058e_e51a_4bdc_bae0_cf09ae6c9811_ff10_1_ctl00_ctl00_TextField" title="OrderQty" class="ms-input" Size="11" style="ime-mode:inactive;" /><br></span></td>
