Although on the surface, keypress and keydown have the same meaning, the essential difference between them is that the system returns the keyboard code from keydown.

Then the TranslateMessage function is translated into characters, and the character value is returned by keypress. So the keyboard code is returned in keydown, and the ASCII character is returned in keypress. So according to your purpose, if you just want to read characters, use keypress, and if you want to read the status of each key, use keydown.

The keyboard presses:

("Element") .keydown ()

This event is triggered when the keyboard is pressed.

$("Element") .keydown (function)

This event is triggered when the keyboard is pressed, and a handling method is bound.

Keystroke:

("Element") .keypress ()

This event is triggered when the keyboard is pressed.

$("Element") .keypress (function)

This event is triggered when the keyboard is pressed, and a handling method is bound.

Keyboard pops up:

("Element") .keyup ()

Triggered when the keyboard key is released.

$("Element") .keyup (function)

Triggers and binds a processing method when the keyboard key is released.
