Scroll to the top of the page using JavaScript?

Question

How do I scroll to the top of the page using JavaScript? The scrollbar instantly jumping to the top of the page is desirable too as I\'m not looking to achieve smooth scroll

Answer 1

Really strange: This question is active for five years now and there is still no vanilla JavaScript answer to animate the scrolling… So here you go:

var scrollToTop = window.setInterval(function() {
    var pos = window.pageYOffset;
    if ( pos > 0 ) {
        window.scrollTo( 0, pos - 20 ); // how far to scroll on each step
    } else {
        window.clearInterval( scrollToTop );
    }
}, 16); // how fast to scroll (this equals roughly 60 fps)

If you like, you can wrap this in a function and call that via the onclick attribute. Check this jsfiddle

Note: This is a very basic solution and maybe not the most performant one. A very elaborated example can be found here: https://github.com/cferdinandi/smooth-scroll
