How can I use a jQuery event to detect changes in an input box?

Question

If I use use $('element').change(..., it'll only detect when the element loses focus. I need to detect it constantly (keypress, copy/paste, etc)

Answer 1

You should handle the input (browsers) and propertychange (IE) events.
This will catch drag&drop and paste events too.

Demo.

Answer 2

If you want it to detect constantly, use .keyup() instead of .change()
