When I wanted to react to any changes to a
input textbox immediately, my first instrinct was to use
onChange, however, is called when the
input loses focus.
onKeyPress then? Isn’t called on backspaces.
onKeyDown, maybe? It does get called, but the effect of the keystroke isn’t yet applied, for the return value determines whether it that is done in the first place. (Same story for
onKeyPress by the way.)
onKeyUp does work a bit, except if someone is holding down a single key, for a while.
The solution: hook
onKeyUp and use
setTimeout with a timeout of 0. Yugh. I hate DOM.
: I actually tested this only on one browser.
