Save cookies with javascript how to specify domain?

Question

I'm using this code to save cookies:

function saveCookie(name,value) {
        var date = new Date();
        date.setTime(date.getTime()+(60*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
        document.cookie = name+"="+value+expires+"; path=/";
        }

My problem is that it saves the cookie with domain "example.com" and I want to write them to ".example.com" so I can also read them from subdomains. This is easy to do with PHP but I don't know how to do it with javascript. How can I add a dot before the domain when I save the cookie?

You already have path in there, domain is specified in the same way.

`path=/; domain=."+window.location.host;` ? – lisovaccaro Jul 18 '12 at 21:14

To permit reading from other sub-domains, try:

'; path=/; domain=.'+window.location.host;
