HTML Input on change of value

Question

Hello,

I have an input tag. This tag does not have the autocomplete feature turned off, thus, one does not necessarily need to release a key to change the value of this field and focus anotehr one. My question is: how can I detect ANY value changes of this particular field, like e. g.

<input onvaluechange="//do following..." />

The JavaScritp attribute onchange does not fire on change of value, only on changes like blur, focus, etc...

Thanks in advance!

EDIT: It also doesn't necessarily be a key press. Due to the autocompletion, the user can simply mouse-click the autocompletion result to change the value. This would not fire an onkeydown event.

You can use the onKeyPress attribute to monitor changes typed in by the user.

For example:

It also doesn't necessarily be a key press. Due to the autocompletion

...and many other non-key-based operations, such as right-click-cut/paste, drag and drop, undo/redo, spellchecker adjustments and so on.

HTML5 defines an oninput event to catch all direct changes.

Unfortunately browser support today isn't there (no support in IE, and there are some bugs in others), so all you can do if you really need to detect all changes to an input value earlier than onchange is to use setInterval to add a poller that constantly compares against the previous value.
