Cookies let you store user information in web pages.
What are Cookies?
Cookies are data, stored in small text files, on your computer.
When a web server has sent a web page to a browser, the connection is shut down, and the server forgets everything about the user.
Cookies were invented to solve the problem 'how to remember information about the user':
- When a user visits a web page, his/her name can be stored in a cookie.
- Next time the user visits the page, the cookie 'remembers' his/her name.
Cookies are saved in name-value pairs like:
When a browser requests a web page from a server, cookies belonging to the page are added to the request. This way the server gets the necessary data to 'remember' information about users.
None of the examples below will work if your browser has local cookies support turned off.
Create a Cookie with JavaScript
JavaScript can create, read, and delete cookies with the
document.cookie
property.With JavaScript, a cookie can be created like this:
You can also add an expiry date (in UTC time). By default, the cookie is deleted when the browser is closed:
document.cookie = 'username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 UTC';
With a path parameter, you can tell the browser what path the cookie belongs to. By default, the cookie belongs to the current page.
document.cookie = 'username=John Doe; expires=Thu, 18 Dec 2013 12:00:00 UTC; path=/';
Read a Cookie with JavaScript
With JavaScript, cookies can be read like this:
document.cookie
will return all cookies in one string much like: cookie1=value; cookie2=value; cookie3=value; Macos server 5 9 crack.Change a Cookie with JavaScript
With JavaScript, you can change a cookie the same way as you create it:
document.cookie = 'username=John Smith; expires=Thu, 18 Dec 2013 12:00:00 UTC; path=/';
The old cookie is overwritten.
Delete a Cookie with JavaScript
6'5 Next To 5'5
Deleting a cookie is very simple.
You don't have to specify a cookie value when you delete a cookie.
Just set the expires parameter to a passed date:
document.cookie = 'username=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/;';
You should define the cookie path to ensure that you delete the right cookie.
Some browsers will not let you delete a cookie if you don't specify the path.
The Cookie String
The
document.cookie
property looks like a normal text string. But it is not.Even if you write a whole cookie string to document.cookie, when you read it out again, you can only see the name-value pair of it.
If you set a new cookie, older cookies are not overwritten. The new cookie is added to document.cookie, so if you read document.cookie again you will get something like:
cookie1 = value; cookie2 = value;
If you want to find the value of one specified cookie, you must write a JavaScript function that searches for the cookie value in the cookie string.
JavaScript Cookie Example
In the example to follow, we will create a cookie that stores the name of a visitor.
The first time a visitor arrives to the web page, he/she will be asked to fill in his/her name. The name is then stored in a cookie.
The next time the visitor arrives at the same page, he/she will get a welcome message.
For the example we will create 3 JavaScript functions:
- A function to set a cookie value
- A function to get a cookie value
- A function to check a cookie value
A Function to Set a Cookie
First, we create a
function
that stores the name of the visitor in a cookie variable:Example
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = 'expires='+ d.toUTCString();
document.cookie = cname + '=' + cvalue + ';' + expires + ';path=/';
}
var d = new Date();
d.setTime(d.getTime() + (exdays*24*60*60*1000));
var expires = 'expires='+ d.toUTCString();
document.cookie = cname + '=' + cvalue + ';' + expires + ';path=/';
}
Example explained:
The parameters of the function above are the name of the cookie (cname), the value of the cookie (cvalue), and the number of days until the cookie should expire (exdays).
The function sets a cookie by adding together the cookiename, the cookie value, and the expires string.
A Function to Get a Cookie
Then, we create a
function
that returns the value of a specified cookie:Example
function getCookie(cname) {
var name = cname + '=';
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) ' ') {
c = c.substring(1);
}
if (c.indexOf(name) 0) {
return c.substring(name.length, c.length);
}
}
return ';
}
var name = cname + '=';
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) ' ') {
c = c.substring(1);
}
if (c.indexOf(name) 0) {
return c.substring(name.length, c.length);
}
}
return ';
}
Function explained:
Take the cookiename as parameter (cname).
Create a variable (name) with the text to search for (cname + '='). Betterzip 4 0 2 – archiving tool boxes.
Pixologic zbrush 2018 mac. Decode the cookie string, to handle cookies with special characters, e.g. '$'
Split document.cookie on semicolons into an array called ca (ca = decodedCookie.split(';')).
Loop through the ca array (i = 0; i < ca.length; i++), and read out each value c = ca[i]).
If the cookie is found (c.indexOf(name) 0), return the value of the cookie (c.substring(name.length, c.length).
If the cookie is not found, return '.
A Function to Check a Cookie
Cookie 5 5 9 1 2 To Centimeters
Last, we create the function that checks if a cookie is set.
If the cookie is set it will display a greeting.
If the cookie is not set, it will display a prompt box, asking for the name of the user, and stores the username cookie for 365 days, by calling the
setCookie
function:Example
function checkCookie() {
var username = getCookie('username');
if (username != ') {
alert('Welcome again ' + username);
} else {
username = prompt('Please enter your name:', ');
if (username != ' && username != null) {
setCookie('username', username, 365);
}
}
}
var username = getCookie('username');
if (username != ') {
alert('Welcome again ' + username);
} else {
username = prompt('Please enter your name:', ');
if (username != ' && username != null) {
setCookie('username', username, 365);
}
}
}
All Together Now
Example
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = 'expires='+d.toUTCString();
document.cookie = cname + '=' + cvalue + ';' + expires + ';path=/';
}
function getCookie(cname) {
var name = cname + '=';
var ca = document.cookie.split(';');
for(var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) ' ') {
c = c.substring(1);
}
if (c.indexOf(name) 0) {
return c.substring(name.length, c.length);
}
}
return ';
}
function checkCookie() {
var user = getCookie('username');
if (user != ') {
alert('Welcome again ' + user);
} else {
user = prompt('Please enter your name:', ');
if (user != ' && user != null) {
setCookie('username', user, 365);
}
}
}
Try it Yourself »var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = 'expires='+d.toUTCString();
document.cookie = cname + '=' + cvalue + ';' + expires + ';path=/';
}
function getCookie(cname) {
var name = cname + '=';
var ca = document.cookie.split(';');
for(var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) ' ') {
c = c.substring(1);
}
if (c.indexOf(name) 0) {
return c.substring(name.length, c.length);
}
}
return ';
}
function checkCookie() {
var user = getCookie('username');
if (user != ') {
alert('Welcome again ' + user);
} else {
user = prompt('Please enter your name:', ');
if (user != ' && user != null) {
setCookie('username', user, 365);
}
}
}
The example above runs the
checkCookie()
function when the page loads.
