Does scrollIntoView()
work in all browsers? If not is there a jQuery
alternative?
It is supported yes, but user experience is... bad.
As @9bits pointed out, this has long been supported by all major browsers. Not to worry about that. The main problem is the way that it works. It simply jumps to a particular element that may as well be at the end of the page. By jumping to it, users have no idea whether:
- page has been scrolled up
- page has been scrolled down
- they've been redirected elsewhere
The first two can be determined by scroll position, but who says users kept track of scroll position before jump was done? So it's an nondeterministic action.
The last one may be true especially if the page has moving header that gets scrolled out of view and remaining page design doesn't imply anything on being on the same page (if it also doesn't have any total height vertical element like left menu bar). You'd be surprised how many pages have this problem. just check them out yourself. Go to some page, look at it at top, then press End key and look at it again. It is likely that you'll think it's a different page.
Animated scrollintoview
jQuery plugin to the rescue
That's why there still are plugins that perform scroll into view instead of using native DOM function. They usually animate scrolling which eliminates all 3 issues outlined above. Users can easily keep track of the movement.
ScrollIntoViewOptions
allows to specify behavior: 'smooth'
. unfortunately there’s no way to easily detect if this option is supported in a browser… –
Undershirt behavior: "smooth"
, but not Chrome or Safari. –
Milagro behavior: "smooth"
, but Safari still is lagging. –
Cornfield block: "center"
is there any alternatives? –
Chlortetracycline Looks like it does: http://www.quirksmode.org/dom/w3c_cssom.html
I use Matteo Spinnelli's iScroll-4 and it works in iOS safari as well. It has three methods scrollTo, scrollToElement and scrollToPage. Let's say you have an unordered list of elements wrapped inside a div. As Robert Koritnik has written above, you need to have that slight animation to show that you have scrolled. The below method achieves that effect.
scrollToElement(element, time);
read please about scrollIntoViewIfNeeded
if(el.scrollIntoViewIfNeeded){
el.scrollIntoViewIfNeeded()
}else{
el.scrollIntoView()
}
You can use jQuery alternative and animate <html>
and <body>
elements:
$('html, body').animate({
scrollTop: $("#myElem").offset().top
}, 1000);
Have not tried this, but seems like piggybacking on built in scrollIntoView function would save much code. Here is what I would do if you want animated action:
- Cache current scroll position of the container as START POSITION
- run built in scrollIntoView
- Cache the scroll position again as the END POSITION
- Return container back to START POSITION
- Animate scrolling to END POSITION
Css solved it guys!! I picked the target id with #idSelected and styled it with css "scroll-margin-top" and defined my margin top in rems (use what ever measurement that suits you).
#idSelected {
scroll-margin-top: 10rem;
}
