1. Definition and Usage

The onkeypress attribute fires when the user presses a key (on the keyboard).

Tip: The order of events related to the onkeypress event:

  1. onkeydown
  2. onkeypress
  3. onkeyup

Note: The onkeypress event is not fired for all keys (e.g. ALT, CTRL, SHIFT, ESC) in all browsers. To detect only whether the user has pressed a key, use onkeydown instead, because it works for all keys.

Note: The onkeypress attribute CANNOT be used with: <base>, <bdo>, <br>, <head>, <html>, <iframe>, <meta>, <param>, <script>, <style>, or <title>.
