Suggestion:

function compararHora(str) {
    str = str.split(':');
    var agora = new Date();
    var varData = new Date();
    ['setHours', 'setMinutes', 'setSeconds'].forEach(function(fn, i) {
        return varData[fn](str[i]);
    });
    if (agora == varData) return 0;
    else return agora > varData ? 1 : -1;
}



console.log(compararHora('05:50:00'));
console.log(compararHora('23:50:00'));

Starting from the format you indicated hh:mm:ss, you can break that string by : and use the methods Javascript gives us to change the time to a date. Then compare if the time is the same, "greater than" or "less than", and in the function I suggest returns respectively 0, 1 or -1;
