Hi!

I use jquery for horizontal scrolling with mousewheel.It is work ..

 $('html').mousewheel(function (event, delta) {
            this.scrollLeft += (delta * 50);
            event.preventDefault();
        });

I want horizontal scrolling Internal Anchor Links click,

I use this code :

   $(".prevscroll").click(function (event) {
               event.preventDefault();
               $.scrollTo(this.hash, 150, { easing: 'elasout' });
        });
or
  $(window).scrollLeft((Number($(window).scrollLeft()) + 50) + 'px');
or
 $('body').scrollLeft(50);

but don't scrolling !!!!

My html code

<script type='text/javascript' src="js/jquery.mousewheel.min.js"></script>
