How to scroll contents of a an element vertically using JavaScript?

in JavaScript on March 10, 2021

We know that we can use on page links (a tag) with id to navigate user on the same page. But that doesn’t always we need. What if we want to scroll down a bit higher or lower but not to a specific element?

Well, in that case, scrollTop DOM property comes handy.

We can use the scrollTop property to set the number of pixels on any element’s content and it should scroll vertically by that many pixels.

We can also use it to get the number of pixels any element has moved down vertically.

Very handy. Isn’t it?

Simply set the property like this syntax

el.scrollTop = number in pixels

Or get the property like this syntax


Things to remember

  • Try not to set the number of pixels in negative. It doesn’t work like margin or padding. JavaScript will convert the negative number to a zero.
  • If you try to scroll any element that is not scrollable, then again JS will set the number to a zero.
  • If you set the scrolling number in pixel greater than the box itself, then it will be set to the maximum box height.

Example: scroll contents using JavaScript

You can make the scrolling smooth just using CSS or a cross-browser solution using jQuery.
