I want to

Answer 1

It seems to me you could split the cookie key-value pairs into an array and base your search on that:

var obligations = getCookieData("obligations");

Which runs the following:

function getCookieData( name ) {
    var pairs = document.cookie.split("; "),
        count = pairs.length, parts; 
    while ( count-- ) {
        parts = pairs[count].split("=");
        if ( parts[0] === name )
            return parts[1];
    }
    return false;
}

Or possibly even the following:

function getCookieData( name ) {
    var patrn = new RegExp( "^" + name + "=(.*?);" ),
        patr2 = new RegExp( " " + name + "=(.*?);" );
    if ( match = (document.cookie.match(patrn) || document.cookie.match(patr2)) )
        return match[1];
    return false;
}
