Can someone help me modify this "password example" so that it works. Currently it just calls "alert()" statements when it is suppose to save, get, and delete a cookie. I need to replace those "alert()" calls with the appropriate cookie call (GetCookie,
SetCookie, DeleteCookie
This program stores a password in the user's browser's cookie file, and then checks that file in the future to confirm the password. Display a 'password correct' or a 'password failed' message. I also want to have a button that deletes the cookie!!
