$(window).scrolltop() not working on mobile

Why is $(window).scrollTop() not working on mobile?

If you are a developer, you may have come across the issue where the $(window).scrollTop() function does not work on mobile devices. This can be frustrating, especially if you are trying to create a responsive website that works on all devices.

One of the reasons for this issue is that mobile devices have a different way of handling scrolling than desktop devices. On a desktop device, you can scroll by using the mouse or trackpad, or by clicking on the scroll bar. However, on mobile devices, scrolling is done by swiping with a finger or tapping on the screen.

Possible solutions

There are a few ways to solve this issue:

  • Use $(document).scrollTop() instead: This function works on both desktop and mobile devices. It returns the current vertical position of the scroll bar for the entire document.
  • Use a plugin: There are several plugins available that can help you handle scrolling on mobile devices. One such plugin is TouchSwipe, which allows you to handle swipes and taps on mobile devices.
  • Check for touch events: You can check if the device supports touch events using the following code:

if ('ontouchstart' in window) {
  // This device supports touch events
} else {
  // This device does not support touch events

By using one of these solutions, you can ensure that your website works correctly on both desktop and mobile devices.
