Question

The onchange event for a HTML input box does not fire until the textbox loses focus. Is there a way to make it fire as soon as the contents change?

Here’s an example of onchange firing after focus loss: http://jsfiddle.net/McjqW/

Answer 1

You are looking for the onkeypress or onkeydown event. Note that this event is not standard, and different browsers may expose this functionality under different names. The DOM level 3 standard defines a keypress event which would be “the” answer, but again I can’t vouch for browser support.

Update: onkeypress reportedly enjoys wide support.
