Definition and Usage
The order of events related to the keypress event:
The keypress() method triggers the keypress event, or attaches a function to run when a keypress event occurs.
The keypress event is similar to the keydown event. The event occurs when a button is pressed down.
However, the keypress event is not fired for all keys (e.g. ALT, CTRL, SHIFT, ESC). Use the keydown() method to also check these keys.
Trigger the keypress event for the selected elements:
Attach a function to the keypress event:
|function||Optional. Specifies the function to run when the keypress event is triggered|
