Element: keypress event

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The keypress event is fired when a letter, number, punctuation, or symbol key is pressed, or else when the Enter key is pressed — including when the Enter key is pressed in combination with the Shift key or Ctrl key. Otherwise, when a modifier key such as the Alt, Shift, Ctrl, Meta, Esc, or Option key is pressed in isolation, the keypress event is not fired.

Warning: Since this event has been deprecated, you should use beforeinput or keydown instead.

The event bubbles. It can reach Document and Window.
