Hi, I’m trying to validate a field for numbers only.  I’ve been trying the following script but it doesn’t work. 

<script type="text/javascript">

             $(document).ready(function () {

                 $('#saveBtn').click(function () {

                     var trial = $('#HomeworkGrade').val();

                     var numbers = /^[0-9]+$/;

                     if (trial.value.search(numbers)==-1) {

                         alert('Correct data is entered')

                         $('#HomeworkGrade').css('background-color', '#fccaf9');

                         $("#HomeworkGrade").focus();

                         return false;

                     }

                 });

             });          

            </script> 

Also tried this: if (trial.value.match(numbers)).

Can you please help me to get this working? I appreciate any ideas in the right direction...thanks.
