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

$(".scrolltop").click(function() {
  $("html, body").animate({ scrollTop: 0 }, "slow");
  return false;
});

.section{
 height:400px;
}
.section1{
  background-color: #333;
}
.section2{
  background-color: red;
}
.section3{
  background-color: yellow;
}
.section4{
  background-color: green;
}
.scrolltop{
  position:fixed;
  right:10px;
  bottom:10px;
  color:#fff;
}

Scroll top
