To only validate the format, you can use this:

var valid = (timeStr.search(/^d{2}:d{2}:d{2}$/) != -1);

If you're trying to validate the values as well, you can try this:

var valid = (timeStr.search(/^d{2}:d{2}:d{2}$/) != -1) &&

            (timeStr.substr(0,2) >= 0 && timeStr.substr(0,2) <= 24) &&

            (timeStr.substr(3,2) >= 0 && timeStr.substr(3,2) <= 59) &&

            (timeStr.substr(6,2) >= 0 && timeStr.substr(6,2) <= 59);
