How can I select a dropdown list in a specific table cell?

How can I select a dropdown list in a specific table cell?

Hi, I’m using JQuery version 1.8.11 with IE10. I  have a table with a simgle row. the table id is #listTable, the <tr>id is #listTableRow and the <td> id is #days.  The row has a number of cells and in each cell there is a dropdown list with the same id: #searchString.  I want to be able to select the the dropdown list in the third cell and set its option to option:first.. I’ve been able to select the td with the code below but not the specific dropdown list.. How can I select the 3rd dropdown list in a table?

 

<script type="text/javascript">

          

 

 

             $(document).ready(function () {

                 var nos = $('#listTable #searchString').length;

                

                 $.each($checkboxes, function () {

                     if ($(this).is(':checked')) {

                      

$('#listTable #days:nth-child(3)').css('border', '2px dashed blue');

                        

                 });

 

             });

                                  

            </script>
