Selector / Traversing Question

Selector / Traversing Question

Hey guys, anybody have a better way to achieve this. I am thinking I took the very long way...
 
//page code
 

<table cellpadding="0" cellspacing="0" border="0">
                              <tr>
                                  <td id="tdVal">
                                    <input name="ctl00$MainContent$gvwWizard$ctl09$txtApprovalOrder" type="text" value="0" maxlength="3" id="ctl00_MainContent_gvwWizard_ctl09_txtApprovalOrder" title="enter the order in which this item should fall in the approval process" class="txtSortOrder" />
                                  </td>
                                  <td id="tdUpDown">                                     
                                        <img border="0" class="imgUp" id="numberUp" src="../Images/number_up.gif" alt="increase approval order" />                                                                
                                        <img border="0" class="imgDown" id="numberDown" src="../Images/number_down.gif"  alt="decrease approval order"  />
                                  </td>
                              </tr>
                          </table>









 

 

//in a function when the image is clicked...get the input box in the TD next to me

inputBox = $(e.target).parent().parent().children(

 "td:first" ).children( "input:first" );
