Determining if an object is visible on the screen (with no reliance on scrollbars)

Is there a way to optimize rendering on a website by only displaying elements on the screen and rendering others when they are in view?

Similar to 3D culling, but for a website ^.^

[update] Is it not feasible to achieve this effect?
[update2] I experimented with LazyLoad (jQuery plugin) but it triggered on window scroll
[update3] Apologies for repeatedly bringing this up, but I am struggling to find a solution

Answer №1

Are you familiar with lazyloading? I recommend checking out lazyload at

Answer №2

If you're looking to optimize image loading on your website, the Lazy Loader plugin is a great solution. You can check out a demo of how it works here.

Lazy Loader, a jQuery plugin written in JavaScript, helps delay the loading of images on lengthy web pages. By only loading images within the user's viewport, it improves page loading speeds and performance.

While Lazy Loader is based on YUI ImageLoader, you may want to consider using the original framework if you're not exclusively using jQuery. Depending on your specific needs, the original framework might be a better fit.

Answer №3

One option to consider is using a library such as this: . The developer provides a demo showcasing a fade-in effect similar to mashable.com if that aligns with your desired outcome.

You have the flexibility to customize and integrate only the necessary components based on your specific website and loading criteria.

Answer №4

While I'm not one to often suggest plugins, jQuery waypoints really excels at what it does and could be just what you're looking for. Why not give it a shot?
