asp.net onkeyup event for textbox
I have an issue with onkeyup event with textbox. my function is to check password strength of the password textbox. so when a users enter his password, it will call the function of checking password strength and show in a label if his password is very weak/weak/medium/strong. Also, the textbox background will show colors according to the strength of the password. however when i type in the password textbox, the label does not show anything and the textbox does not change color.
