How do I check if an element is really visible with JavaScript?
dom, javascript, visibility
Solution
For the point 2.
I see that no one has suggested to use `document.elementFromPoint(x,y)`, to me it is the fastest way to test if an element is nested or hidden by another. You can pass the offsets of the targetted element to the function.
Here's PPK test page on elementFromPoint.
From MDN's documentation:
The `elementFromPoint()` method—available on both the Document and ShadowRoot objects—returns the topmost Element at the specified coordinates (relative to the viewport).
Problem
In JavaScript, how would you check if an element is actually visible? I don't just mean checking the `visibility` and `display` attributes. I mean, checking that the element is not - `visibility: hidden` or `display: none` - underneath another element - scrolled off the edge of the screen For technical reasons I can't include any scripts. I can however use Prototype as it is on the page already.
