Definition and Usage

The order of events related to the keypress event:

  1. keydown- The process of key press
  2. keypress - The key is pressed
  3. keyup- The key is released

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

The keypress event is similar to the keydown event. It occurs when a key is pressed.

However, the keypress event does not trigger for all keys (such as ALT, CTRL, SHIFT, ESC). Use the keydown() method to check these keys.


Syntax

Trigger the keypress event of the selected element:

$(selector).keypress() Try it Yourself

Add a function to the keypress event:

$(selector).keypress(function) Try it Yourself

Parameters Description
function Optional. Specifies the function to run when the keypress event is triggered.
