How to get session cookie via javascript?

Question

I need to make a script that when the user arrives at my utm via url, I must record a session cookie. This cookie will expire when the browser closes. Can anyone help me with this?

Answer 1

To create a cookie for session, just associate a string containing the format chave=valor to the property cookie of document:

document.cookie = "[nomeDoCookie]=[ValorDoCookie]";

If you wish to persist this cookie between browser sessions, you can specify an expiration date in format Gmtstring:

document.cookie = "[nomeDoCookie]=[ValorDoCookie]; expires=[data]";

Examples:

document.cookie = "cookie2=sample";
document.cookie = "cookie2=true; expires=Fri, 31 Dec 9999 23:59:59 GMT";

However it is worth mentioning that there is no guarantee that the session cookie will be waived when all windows are closed - Chrome, for example, has a setting that by default keeps session cookies alive:

MDN - Document cookie.
Stackoverflow - Chrome doesn’t delete Session cookies

Answer 2

Use the plugin

http://plugins.jquery.com/cookie/

Create

$.cookie("exemplo", "abc");
$.cookie("exemplo", "abc", { expires: 7 }); 
$.cookie("exemplo", "abc", { path: '/admin', expires: 7 });

Read

alert( $.cookie("exemplo") );

Remove

$.removeCookie("exemplo");

Answer 3

To create the cookie:

  document.cookie = "username=[utilizador]; expires=[dia que expira], [18 Dec 2013 12:00:00 UTC]";

To read the cookie:

var x = document.cookie;

Answer 4

Marcos,

in accordance with wikipedia, to do what you want should be created a cookie Session, which is nothing more than a cookie with no expiration date.

When you create the cookie with no expiration date, it is only in memory and once the browser is closed the cookie is removed.

A Session cookie, also known as an in-memory cookie or Transient cookie, exists only in Temporary memory while the user navigates the website. [12] Web browsers normally delete Session cookies when the user closes the browser. [13] Unlike other cookies, Session cookies do not have an expiration date Assigned to them, which is how the browser Knows to Treat them as Session cookies.
