Question

I am using a very long expandable form. For example if question 1 is answered with “Yes”, question 1.1 will show and so on.

This works well with the following (simple) jquery script:

Selectmenu

<script type="text/javascript">
    $(document).ready(function() {
        $(".question").change(function() {
            var itemValue = $(this).children(':selected').val();

            if(itemValue != "" &&  itemValue != "N")
            {
                $(".questiont").show();
            }
            else
            {
                $(".questiont").hide();
            }
        }); 
    }); 
</script>

HTML

<select name="question1[]" class='required txtBox'>
              <option selected="selected"></option>
              <option value="J">Yes</option>
              <option value="N">No</option>
            </select>
<table>
    <tr class="questiont" style="display:none; border-collapse:collapse;">
              <td>4.2</td>
              <td>Textarea</td>
              <td><textarea name="questiont[]" class="txtBox"></textarea></td>
            </tr>
</table>

The problem is, that if 1 is “Yes” and thus 1.1 is shown, 1.1 should be filled. I am using jQuery validate for that.

The problem is that i don’t know how to combine the validation with a hidden or shown status.

Try this code:

if(itemValue != "" &&  itemValue != "N")
            {
                $(".questiont").show();
                $('.questiont').toggleClass('required');
            }
            else
            {
                $(".questiont").hide();
                $('.questiont').toggleClass('required');
            }
