jQuery scrollTop() Method The scrollTop() method sets or returns the vertical scrollbar position for the selected elements. Tip: When the scrollbar is on the top, the position is 0.
Use the scroll() Function to Scroll to an Element in JavaScript. The element interface's scroll() function scrolls to a specific set of coordinates within a given element. This is suitable for Chrome and Firefox and not for the rest. Copy window.
The scrollTo() method of the window Interface can be used to scroll to a specified location on the page. It accepts 2 parameters the x and y coordinate of the page to scroll to. Passing both the parameters as 0 will scroll the page to the topmost and leftmost point.
$('html, body').animate({scrollTop: $("#page").offset().top}, 2000);
If it's not working why don't you try using jQuery's scrollTop method?
$("#id").scrollTop($("#id").scrollTop() + 100);
If you're looking to scroll smoothly you could use basic javascript setTimeout/setInterval function to make it scroll in increments of 1px over a set length of time.
jQuery now supports scrollTop as an animation variable.
$("#id").animate({"scrollTop": $("#id").scrollTop() + 100});
You no longer need to setTimeout/setInterval to scroll smoothly.
To get around the html
vs body
issue, I fixed this by not animating the css directly but rather calling window.scrollTo();
on each step:
$({myScrollTop:window.pageYOffset}).animate({myScrollTop:300}, {
duration: 600,
easing: 'swing',
step: function(val) {
window.scrollTo(0, val);
}
});
This works nicely without any refresh gotchas as it's using cross-browser JavaScript.
Have a look at http://james.padolsey.com/javascript/fun-with-jquerys-animate/ for more information on what you can do with jQuery's animate function.
Looks like you've got the syntax slightly wrong... I'm assuming based on your code that you're trying to scroll down 100px in 800ms, if so then this works (using scrollTo 1.4.1):
$.scrollTo('+=100px', 800, { axis:'y' });
Actually something like
function scrollTo(prop){
$('html,body').animate({scrollTop: $("#"+prop).offset().top +
parseInt($("#"+prop).css('padding-top'),10) },'slow');
}
will work nicely and support padding. You can also support margins easily - for completion see below
function scrollTo(prop){
$('html,body').animate({scrollTop: $("#"+prop).offset().top
+ parseInt($("#"+prop).css('padding-top'),10)
+ parseInt($("#"+prop).css('margin-top'),10) +},'slow');
}
