That doesn't really matter in this instance since you're comparing it
against the empty string with the goal of determining if the field is empty
or not.  But, here's a function that I've had great luck with:

function isWhitespace(str)
    var regex = /^\s+$/;
    return regex.test(str);
    return true;

Best of luck,
