Yeesh.. what a mess! No worries, we can do some formatting. You’ll notice that there are = and ; interspersed throughout the cookie text. The = denotes key=value pairs while the ; delimits the individual pairs. So in order to clean things up a bit, you might write something like this:
See it? In green? I just added my email address as a cookie to your machine. Feel free to drop me a line! 🙂 Of course you can delete it if you want…
Moving on, let’s say you want the value of just 1 key=value pair within the cookie. What to do..? Well, you could write a custom function to do something like this:
And from there, you can do all kinds of things depending on whether or not a certain key=value pair exists as a cookie on a user’s machine. One of the most common uses for cookies is keeping users logged in to a credentialed website (such as Facebook, Twitter, of YouTube) by placing a cookie on the user’s machine once successfully logged in. The logic goes something like:
if (key=value exists) → show logged in content, if (key=value doesn’t exist) → prompt user to log in
that kind of thing.
