Найти нулевые или пустые значения в AJAX Response

Question

{"prepaymentList":[{"years":1,"bps":null,"targetRate":0.0236187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":2,"bps":null,"targetRate":0.0236187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":3,"bps":null,"targetRate":0.0236187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":4,"bps":null,"targetRate":0.0236187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":1,"bps":null,"targetRate":0.0186187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":2,"bps":null,"targetRate":0.0186187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":3,"bps":null,"targetRate":0.0186187,"TotalValueString":"","ShockString":"","KeyRate":""},{"years":4,"bps":null,"targetRate":0.0186187,"TotalValueString":"","ShockString":"","KeyRate":""}],"keyRateList":[{"years":1,"bps":null,"targetRate":null,"TotalValueString":"","ShockString":"","KeyRate":"2.51506"},{"years":2,"bps":null,"targetRate":null,"TotalValueString":"","ShockString":"","KeyRate":"3.03467"},{"years":3,"bps":null,"targetRate":null,"TotalValueString":"","ShockString":"","KeyRate":"3.48070"},{"years":4,"bps":null,"targetRate":null,"TotalValueString":"","ShockString":"","KeyRate":"3.87485"}],"stillRunning":true,"prepaymentLength":5}

Это мой ответ AJAX, полученный от моего вызова JQuery ajax. Как мне пройти через это и посмотреть, есть ли в нём пустые или пустые объекты с использованием JQuery?

Answer 1

$.each(prepaymentList, function(index, value) {
    if (value == null || value == ' ') {
        alert(index+" is null!");
    }
}

Непроверенные.
