Hello,

I just got into the subject jquery und already have a problem:

I built two scripts into my new project: „scroll to“ and „mousewheel“.

The mousewheel effect works very well and I can slide from site to site. But when I use scroll to in the navigation and jump to an stay/ anchor (slide) I can not use the mousewheel effect to scroll upwords. Everything switches downside, I can scroll down but then I end up in empty space.

I guess its because the scrollarbor changes position when using the „scroll-to“ but not when using the mousewheel effect?

I´d really appreciate any kind of tips or help.

This is what the code with jquery looks like:

1. <script type='text/javascript' src='http://code.jquery.com/jquery-1.8.3.js'></script>
   <script type="text/javascript">
   
   </script>
   
   <script type="text/javascript">
   
   $(document).ready(function() {
   
     $('a[href*=#]').bind("click", function(event) {
     
      event.preventDefault();
    
      var ziel = $(this).attr("href");
     
      $('html,body').animate({
      
       scrollTop: $(ziel).offset().top
     
      }, 2000 , function (){location.hash = ziel;});
       });
   return false;
   });
   </script>
   
   <script type='text/javascript'>//<![CDATA[
