  <pre><code>$(".jbcheckboxSignUp").click(function () {
      $(".jbcheckboxSignUp").toggleClass("select");
      var $checkbox = $("#jbCheckBoxSignUp");
      $checkbox.attr('checked', !$checkbox.attr('checked'));
      if ($("button.SignUpButton").attr('disabled') &amp;&amp; $('#SignUpForm').validator() &amp;&amp; $("#signUpEmail").val()!=""  ) {
          $("button.SignUpButton").removeAttr('disabled');
      } else {
          $("button.SignUpButton").attr('disabled','disabled');
      }
  });
