Wanted this in client side using jquery. Please help Below is the code I have written. Some code line are repeating how to optimize it more ??

 $(function () {
             $('#MainContent_G2 > tbody  > tr').each(function (index, row) {
                 var checkedArr = $(row).find('input[type="checkbox"]:checked');
                 if (checkedArr.length === 0) {
                     var textbox = $(row).find('input[type="text"]');
                     $(textbox).attr('readonly', true);
                 }

                 $(row).find('input[type="checkbox"]').each(function(index, checkbox) {
                     $(checkbox).change(function () {
                         if (this.checked) {
                             $(this).closest("tr").find('input[type="text"]').attr('readonly', false);
                         }

                         var checkedArr = $(row).find('input[type="checkbox"]:checked');
                         if (checkedArr.length === 0) {
                             var textbox = $(row).find('input[type="text"]');
                             $(textbox).attr('readonly', true);
                         }
                     });
                 });

             });
         });
