jQuery - ScrollTop without animation

Question

How can I use the scrolltop without an animation

This code works:

var offTop = $('#box').offset().top;
offTop  = offTop-43;
$('#mainCt').animate({scrollTop: '+=' + offTop + 'px'}, 400);

And here are my (not working solutions):

$("#mainCt").scrollTop('+=' + offTop + 'px');                 // doesn't work
$("#mainCt").scrollTop('+='+offTop);                          // doesn't work
hhh = setTimeout(' $("#mainCt").scrollTop('+offTop+');',800); // doesn't work

Answer 1

Try this:

var offTop = $('#box').offset().top - 43;
$('#mainCt').scrollTop(offTop);

The scrollTop property accepts just an integer, no suffixes or units required.

Answer 2

maybe if you don't want an animation or anything fancy just use an anchor

<a name="top"></a>

Place it where you need to scroll

and in your function where you are calling use

document.location.href="#top";

You could also create a function to append the anchor before the element, do the document.location thing and later remove that anchor.

Skip jQuery. Just use JavaScript:

window.scroll(0, 0);
