Animated javascript scrollBy -

i have next button when clicked want scroll downwards page 517px.

using next code (which have found on site) have made button scroll in smooth animated way. need add together that?

the code using follows:

function scrollbypixels(x, y) { window.scrollby(x, y); }

and next on actual button:

onclick="javascript:scrollbypixels(0, 517)"

thanks in advance

function scrollbypixels(x, y) { $('html,body').stop().animate({ scrollleft: '+=' + x, scrolltop: '+=' + y }); }

...or simple plugin:

$.fn.scrollby = function(x, y){ homecoming this.animate({ scrollleft: '+=' + x, scrolltop: '+=' + y }); };
