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:
- onkeydown
- onkeypress
- 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>.
2. Differences Between HTML 4.01 and HTML5
