Reading Cookies using Javascript

To read cookies with Javascript:

var ko = document.cookie;

document.write(ko);

or

document.write(document.cookie);

-We named a variable ko because it's easy to type.
-We stored the cookies in ko
-We printed all cookies set by our domain to the browser, assuming there are some.
-The second document.write is just a shortcut.

Now, let's set two cookies first:

document.cookie="iltccook=got it ONE;domain=ilovethecode.com;expires=Mon, 18-Feb-2036 05:43:38 GMT;path=/";
document.cookie="iltccook2=got it Two;domain=ilovethecode.com;expires=Mon, 18-Feb-2036 05:43:38 GMT;path=/";

Then we'll read and split them into usable pieces.

var ko=document.cookie.split("; ");

-We split the cookies into pieces by the semicolon and space. (semicolon-space is how all browsers store multiple cookies)
-Now we'll print out their pieces.

document.write(document.cookie + "<br>");
document.write(ko[0] + "<br>");
document.write(ko[1] + "<br>");

-The first document.write prints all cookies from our domain.
-The second document.write prints the cookie at index zero (aka the first cookie).
-The third document.write prints the cookie at index one (aka the second cookie).

You could split these down further still like so:

var ji=ko[0].split("=");

-ko[0] has our first cookie.
-We split ko[0] by the equals sign and store the pieces in the variable we name ji
-Now we print the pieces with four dashes in between to make it look pretty.

document.write(ji[0] + " ---- " + ji[1]);
