How can I list all cookies for the current page with Javascript?

Is there any way to, with help of Javascript, list all cookies associated with the current page? That is, if I don’t know the names of the cookies but want to retrieve all the information they contain.

Answer

You can list cookies for current domain:

function listCookies() {
    var theCookies = document.cookie.split(';');
    var aString = '';
    for (var i = 1 ; i <= theCookies.length; i++) {
        aString += i + ' ' + theCookies[i-1] + "n";
    }
    return aString;
}

But you cannot list cookies for other domains for security reasons
