cookies dont work on Chrome

I am using a simple javascript code like this to play around with cookies

var theCookie = "login = ScottPilgrimVStheWorld";

document.cookie=theCookie;
alert(document.cookie);

I have just a simple html page with a body, a header and this javascript code.

Problem is , this is working in IE and FF but not in GC 33.0.1750.154 m. I get an empty alert box. I took a glance at the GC settings and found nothing on blocking/unblocking Cookies. What is happening? Any tips?

Thanks in advance.

EDIT

Here is another function for reading cookies 

function getCookie(searchName)
{
var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++)
{
var cookieCrumbs = cookies[i].split("=");
var cookieName = cookieCrumbs[0];
var cookieValue = cookieCrumbs[1];
if (cookieName == searchName)
{
return cookieValue;
}
}
return false;
}

No spaces are allowed in the assignment string added to the cookie jar. Try

var theCookie = "login=ScottPilgrimVStheWorld";

Tested on chrome 33 ( 33.0.1750.154 ).

edit: chris97ong is right in his claim that you need additional logic to extract a single cookie from the cookie jar document.cookie. if you need that, use his code or match against a regex:

var mycookie = document.cookie.replace(/(^|;)login=([^;]+)(;|$)/, "$2");

Try modifying variable theCookie:

var theCookie = "login=ScottPilgrimVStheWorld;";

We must do this because as stated in W3Schools, the template for a cookie is

[cookie-name]=[cookie-name-val]; [Next is optional] expires=[expiry_date].

Also, I don't think you can just get the cookie directly like that. You have to create a function:

function getCookie(cname)
{
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) 
{
var c = ca[i].trim();
if (c.indexOf(name)==0) return c.substring(name.length,c.length);
}
return "";
}

So you change your alert to something like this:

alert(getCookie("login"));

Hope that helped.
