Definition and usage of keypress

The keypress event is similar to the keydown event. This event occurs when the button is pressed. It occurs on the element that is currently in focus.

However, unlike the keydown event, the keypress event occurs every time a character is inserted.

The keypress () method triggers the keypress event, or specifies the function to run when the keypress event occurs.

Note: if you set it on a document element, this event occurs regardless of whether the element gets focus or not.
