jQuery - Keystrokes

The jQuery event.which will return which keyboard key was pressed.

Type a character in the textbox. Watch what happens when you press the key; hold the key down, and the release the key.

There are a few events to keep in mind when you are trying to detect and validate input which are:

• .keydown() - all keys trigger this...even function keys like Shift, Enter, Delete, etc.
• .keypress() - excludes non-printing keys such as Shift, Enter, Delete, etc.
• .keyup() - triggered when a key is released.
