Why doesn't this function accept the .on('keydown') method?

I used this code, it works. What's it actually looking for?

$('.hint').hide(); $('input').on('keydown', function(e) { $(this).focus(); $(this).next().show(); });

With the on( ) function, the first parameter is an event, and the second parameter is an anonymous function that gets executed when the event occurs. In this case the parser is looking for the 'keydown' event to occur.

The keydown event is sent to an element when the user first presses a key on the keyboard. As soon as that happens, your function will execute.

See the jQuery documentation for more information about the 'on( )' method: http://api.jquery.com/on/
