jQuery .scroll() event not firing consistently in mobile browsers
I'm following best practices but I need some guidance on I'm working through a tutorial and I'm performance testing and I'm upgrading from an older version and I'm working with an scenario where the `.scroll()` event in jQuery is not firing consistently on mobile browsers, specifically on iOS devices... I have a long page that users can scroll through, and I'm trying to trigger an animation based on the scroll position. However, I've noticed that the scroll event only fires sporadically, especially when the page is scrolled quickly. Here's a snippet of my code: ```javascript $(document).on('scroll', function() { let scrollTop = $(this).scrollTop(); if (scrollTop > 300) { $('#myElement').fadeIn(); } else { $('#myElement').fadeOut(); } }); ``` I've tested this across various devices with different browsers, and it seems to be more prominent on Safari for iOS. I’ve also tried throttling the scroll event using lodash’s `_.throttle()` to reduce the number of times the function executes: ```javascript const throttledScroll = _.throttle(function() { let scrollTop = $(this).scrollTop(); if (scrollTop > 300) { $('#myElement').fadeIn(); } else { $('#myElement').fadeOut(); } }, 100); $(document).on('scroll', throttledScroll); ``` Despite these attempts, the scenario continues. I've also checked for any CSS properties that might be affecting the visibility of `#myElement` and there aren't any animations or transitions that could conflict with the `fadeIn()` and `fadeOut()` methods. The element is present in the DOM and has initial styles set to `display: none;`. When I debug, I can see that the event is not firing at all during fast scrolls, and there are no behavior messages in the console. Is there something I might be missing when handling scroll events on mobile browsers? Any insights or additional debugging tips would be greatly appreciated. Any help would be greatly appreciated! This is my first time working with Javascript 3.9. Is this even possible? Thanks for taking the time to read this! This issue appeared after updating to Javascript 3.11. How would you solve this? Thanks, I really appreciate it! The project is a microservice built with Javascript. Hoping someone can shed some light on this.
