Event Handler Not Triggered on Click
Button or element has an onclick handler or click listener attached but clicking doesn't trigger it. The element responds to other interactions but the click handler isn't called. This often happens after dynamically adding elements or refactoring event binding.
Handler is defined and looks correct but isn't invoked when clicked.
Error Messages You Might See
Common Causes
- Event listener attached before element exists in DOM
- Element dynamically added after event listener registration
- Element has pointer-events: none CSS, preventing interaction
- Element covered by invisible overlay with higher z-index
- Event handler throws error silently, execution stops
How to Fix It
Verify element exists before attaching listener: querySelector should find it. Use event delegation (attach to parent) for dynamically added elements. Check CSS: pointer-events should not be 'none'. Look for overlays in dev tools inspector. Add console.log to handler to confirm it's called. Use addEventListener with passive flag: addEventListener('click', handler, {passive: true})

Get HelpFrequently Asked Questions
How to attach handlers to dynamic elements?
Use event delegation: attach to parent that exists. document.addEventListener('click', (e) => { if (e.target.matches('.button')) { ... } })
How to debug if handler is called?
Add console.log at handler start. Check console when clicking. If not logged, handler not called.
What CSS blocks clicks?
pointer-events: none prevents clicks. display: none hides element. z-index lower than overlay covers element.
