Discovering if a page can be scrolled in Angular

Hey there, I recently started working with Angular and created an app using the angular material stepper. The issue I'm facing is that some of the steps have longer content, causing the page to become scrollable. I am now trying to find a way to determine if the page or its content exceeds the screen height so I can display a "Scroll Down" image or animation. I want to avoid showing this animation if the page is not scrollable.

Although a scrollbar appears on the right side when the content overflows, I still want to include this feature. Can you provide me with suggestions on how to tackle this problem?

Answer №1

To determine if the document has been scrolled, you can compare the scroll height of the document with the window height.

setInterval(function() {
  console.log(x = document.documentElement.clientHeight);
  console.log(y = document.body.scrollHeight);
  console.log("document has scroll: ", y > x)
}, 1000)
<div style="height: 600px">
 a div... go to full page and scroll will be gone
</div>
