Read a javascript cookie by name

Question

I have set a cookie using

document.cookie = 
    \'MYBIGCOOKIE=\' + value + 
    \'; expires=\' + now.toGMTString() + 
    \'; path=/\';

No

Answer 1

The simplest way to read a cookie I can think is using Regexp like this:

**Replace COOKIE_NAME with the name of your cookie.

document.cookie.match(/COOKIE_NAME=([^;]*);/)[1]

How does it work?

Cookies are stored in document.cookie like this: cookieName=cookieValue;cookieName2=cookieValue2;.....

The regex searches the whole cookie string for literaly "COOKIE_NAME=" and captures anything after it that is not a semicolon until it actually finds a semicolon;

Then we use [1] to get the second item from array, which is the captured group.
