website templates
The novice programmer races web templates
up and asks breathlessly, "Is it true? Can I really
create cookies with JavaScript?" "Sure is,"
you say, "and it's easy." "Wow," crie
the NP, "tell me how!"Cookies are both loved
website templates and hated (so be careful before using
them), and you ca indeed set them using JavaScript.
free website templates A cookie is text
that the browser stores on the local machine, and which
you can access at a later date. A common use of cook-!
ies is to store shopping cart information, that is, a
user's purchases web site templates while he she browses
around a commercial site. free web templates If you're
experienced with the Web, you know about cookies. You
should be aware that cookies really annoy some people
(7 almost count mysett among them), so beiutiicious: in
using them if you have to. Also, you should know that
most browsers set limits on the maximum number of cookies.
'' they'll store, such as 200, so
don't set too many. I wish all Web authors were so considerate-I've
seen a single page attempt to set nearly one hundred cookies.free
web site templates The cookie property of a page's document
object holds the actual cookie text,, I and unless you
make special preparations, you'll only see the cookie
text I clicks a button and retrieves the cookie's text
when the user clicks another To create a cookie, all you
need to do is set document-cookie to a string contain-1
ing keyword/value pairs, separated by semicolons.

For instance, I'll call the cookie
in this example "greatCookie" and give it
the text "This is the cookie text." To make
the cookies expire on September 2, 2000 (that is, set
a date for when the browser will delete the cookie)
website templates I would use the expires keyword and
set document.cookie to "greatCookie To
read the cookie free
web templates you only need to search
the text in document.cookie (which is automatically
loaded) for the beginning of the cookie text. In this
case, the cookie text begins with "greatCookie=",
so I'll search for that using the JavaScript String
class's indexof method, which returns the location at
which "great,Cookie=" appears in the text.
Next web site templates I'll use the String class's
substring method to retrieve the actual cookie text,
like this, in a function named getCookie. free web templatesNote
that if you have more than one cookie set, you should
search for the end of the cookie you're looking for
as well, because they're all stored in one long string,
and the following code will return everything after
the location at which greatCookie= appears: we worked
through a lot of JavaScript syntax.I get an error every
time I try to use it..free web site templates"That's
because the Date class is part of the Java util package,
and you have to import that package before you can use
it." The NP asks, "Import it?" The classes
that Sun has created for you to use are stored in class
libraries called packages
