jquery - How do I focus on an input inside a table cell? -

i have inputs inside table cells

<td alt="" class="timesheet-highlight"><input type="text" id="c6r1" name="c6r1" size="7" value="0.00" class="form-control"></td> 

when tab onto table cell applied class timesheet-highlight. having trouble figuring out how focus input inside cell. there multiple inputs in table , id's generated dynamically there no way know be. cells may not have inputs.

i can fire event when tab onto cell this

.on('key-focus', function (e, datatable, cell) {     if ($('td').hasclass('timesheet-highlight')) {         alert('hi');     }                 }); 

i using datatables , full code generate said table:

$(document).ready(function () {         var grid = $('#tbltimesheet').datatable({             "scrolly": "567px",             "paging": false,             "sscrollx": "100%",             keys: {                 classname: 'timesheet-highlight'             }         });         grid         .on('key-focus', function (e, datatable, cell) {             if ($('td').hasclass('timesheet-highlight')) {                 alert('hi');             }          });         /*.on('key-blur', function (e, datatable, cell) {             $('#details').html('no cell selected');         });*/     }); 

the .on('key-focus'.... function has cell parameter cell on focus on.

by invoking cell.node() 'td' element if understand correctly, want this:

.on('key-focus', function (e, datatable, cell) {    var inputfieldinselectedtd = $(cell.node()).find('input');    if (inputfieldinselectedtd) {       inputfieldinselectedtd.focus();    } });
