How to Fix: html <input type="text" /> onchange event not working

Learn how to fix: html <input type="text" /> onchange event not working.

Quick Answer: Try checking your system settings or restarting.

However, in your case, you want the event to be triggered every time the user types something in the text box. To achieve this, you can use the oninput event instead.
