Key code comparison table Introduction

About the key code:

1. A keyCode is a numeric value associated with a specific keyboard key that is provided by the browser when a keyboard event occurs.

2, when the user presses a key on the keyboard, JavaScript can access the key code through the event object to determine which key was pressed.

3. Key codes are commonly used in the following JavaScript events:

(1), keydown event: triggered when the user presses any key on the keyboard.

(2), keyup event: triggered when the user releases a key on the keyboard.

4, key code restrictions: no case, does not limit the keyboard layout, function keys do not produce key codes.

5, the key code may be abandoned in the future, and other schemes can be used to replace the key code.
