 * Can anyone see any reason why this simple script doesn’t work with the WordPress
   included jquery (v1.11 -1.12)?
 *     ```
       <script type="text/javascript">
   
       $(document).ready(function () {
   
           $(window).scroll(function () {
               if ($(this).scrollTop() > 500) {
                   $('.scrollup').fadeIn();
               } else {
                   $('.scrollup').fadeOut();
               }
           });
   
           $('.scrollup').click(function () {
               $("html, body").animate({
                   scrollTop: 0
               }, 900);
               return false;
           });
   
       });
       </script>
       ```
   
 * It’s a simple script for a back-to-top button. If I manually load jquery 2.x 
   from Google or elsewhere, it works just fine.

 * Solved.
 * It’s due to wordpress loading jQuery in no conflict mode.
 * Either replacing $ with jQuery, or setting $ as a function of jQuery on document
   ready works.
