// Overlay a transparent div to catch events on a disabled input
// Who says you can't get an echo from a mute? Here we go!
var disabledInput = document.getElementById('disabledInput');
var overlay = document.createElement('div');
overlay.style.cssText = `position: absolute; width: ${disabledInput.offsetWidth}px; height: ${disabledInput.offsetHeight}px; opacity: 0; zIndex: 1000;`;
overlay.onclick = () => alert('Oops! A wild event appeared!');
disabledInput.parentNode.insertBefore(overlay, disabledInput.nextSibling);

The concept here is to directly overlay a transparent div upon the disabled input. This div can capture the click event even when the input itself cannot. Fear not, we're not in Hogwarts, just vanilla JS!

Make the Disabled Dance

When dealing with disabled form fields, there are numerous strategies to help them groove to the user's beat. For example, the pointer-events: none CSS property can be an ally, allowing click events to be detected on elements beneath. But beware, not all browsers may fancy this dance move.

When it comes to cascading updates on properties like "disabled," jQuery's prop() method takes the lead over its sibling, attr(). This is especially true for dynamic forms responding to user interactions.

Post Submission Notes:

While toggling between disabled and activated states, verify the input fields don't get posted unless the interaction is activated. This is not Inception, you know, we need to stay in the real world!

Accessibility Launchpad:

Strive for solutions that cater to all users, by focusing on accessibility. Making sure visual feedback, like cursor changes, unveils the magic trick for users, prominently indicates the act on the stage.

Harness Readonly Inputs

An alternative strategy is to use readonly instead of disabled. This magician doesn't shy away from interaction, allowing all events without breaking a sweat. Styling them with CSS gives them the guise of a disabled input, fooling all but the most observant!

Alternative Techniques For Extra Showmanship

Custom Coat CSS

Customize the user-select properties, tricking the user that the field is disabled. A classic misdirection in CSS, giving you all the usability without compromising the show!

Old Browsers Need Some Love Too!

Older browsers not vibing with pointer-events? No worries! Use cover elements or state toggling using JavaScript. Ensuring cross-browser compatibility brings the same joy to every user.
