Definition and usage

The complete key press process is divided into two parts: 1. The key is pressed; 2. The key is released.

A keydown event occurs when a button is pressed.

The keydown() method triggers the keydown event, or specifies the function to be executed when a keydown event occurs.

Note:If the event is set on a document element, the event will occur regardless of whether the element has focus or not.

Tips:Please use .which propertyTo determine which key is pressed (Try it yourself).
