Get cookie by name

Question

I have a getter to get the value from a cookie.

Now I have 2 cookies by the name shares= and by the name obligations= .

I want to

Answer 1

My solution is this:

function getCookieValue(cookieName) {
    var ca = document.cookie.split('; ');
    return _.find(ca, function (cookie) {
        return cookie.indexOf(cookieName) === 0;
    });
}

This function uses the Underscorejs _.find-function. Returns undefined if cookie name doesn't exist
