Changing hidden field if any checkbox is checked

Changing hidden field if any checkbox is checked

I've obviously got something wrong here. How do I pass a "interestsYes" or "interestsNo" to a hidden field based on whether any of eight checkboxes are checked? Here's what I have, which basically says, "If any checkbox is checked, set the hidden field "interestAny" to "Yes". If no checkboxes are checked, set the hidden field "interestAny" to "No".

  2. $(document).ready(function() {
  3. if ($("#clientForm input:clientInterest:checked").length > 0)
  4. {
  5. $('#interestAny').val($(this).val('Yes'));
  6. } else {
  7. $('#interestAny').val($(this).val('No'));
  8. }
  9. });

  11. In the form we have this hidden field:

  13. <input type="hidden" name="interestAny" value="">
