Needing jQuery listener for input field - keyup and change not working

开发者_Go百科I need to enable a submit button on my form once the user enters some text into the email address field. Problem is they may be on the form for the second or third time, and the browser saves their email addresses in a drop-down menu under the input.

See here: http://i.imgur.com/7Q40A.jpg

When they click that, it doesn't work. How can i get jquery to listen for that as well?


check the email input box value of keydown event.


Very strange. When I tried it yesterday with .change instead of with .keyup, it did not work. But today it is. Thanks anyway.
