Events onKeyPress, onKeyUp, onKeyDown, onChange - difference

What is the difference between Javascript events onKeyPress, onKeyUp, onKeyDown and onChange ? Can you please give an example, what each of them do and when it should be used ?

Hi,

All four javascript events are specific and quite different. The diffecrences can be explained in case of input field or textarea. Events onKeyPress, onKeyUp, onKeyDown occur at different time, when you press keyboard keys. Event onChange occurs when the value of the element is changed and element lost its focus.

Order of Javascript onKey events:
onKeyDown - occurs first, when user presses a key and before text is entered
onKeyPress - occurs second, when text is entered
onKeyUp - occurs third, when user releases a key
