In-Depth Information
A cookie can only be read by the domain that created it anyway, but doing this will allow all
subdomains
of sitepoint.com (such as javascript.sitepoint.com and books.sitepoint.com) to
read it.
Secure Cookies
Adding
"; secure"
to the end of the cookie will ensure that it's only transmitted over a
secure HTTPS network:
document.cookie = "name=Batman; secure"
Deleting Cookies
To remove a cookie, simply set it to expire at a time in the past:
document.cookie = "name=Batman; expires=Thu, 01 Jan 1970
↵
00:00:01 GMT"
If a cookie is a session cookie, it will expire when the tab or window is closed.
Note: A Cookie Library
JavaScript's cookie handling is quite basic and can also be quite cumber-
some. Many developers use a library such as
Cookies.js
or
jsCookie.
You
could even develop your own set of functions to make dealing with cookies
easier.
