Name

keyCode — NN n/a IE 4 DOM n/a

Synopsis

Read/Write

The Unicode key value for the keyboard key that triggered the event. For onKeyPress events, the value represents the actual character displayed in a text box (e.g., 65 for “A” and 97 for “a”). But for onKeyDown and onKeyUp events, only the uppercase value is returned, regardless of the case of the character that is rendered. If the event is not keyboard driven, the value is zero. While you may change the value of this property, it does not influence the character displayed in the text field. See Chapter 6 about capturing keyboard events.

Example

if (event.keyCode == 65) {
    ...
}

Value

Integer.

Default

None.
