javascript将C#json序列化的Date对象转换成正常的Date格式

function ChangeDateFormat(cellval) {
            var date = new Date(parseInt(cellval.replace("/Date(", "").replace(")/" + ""), 10));
            var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth + 1;
            var currentDate = date.getDay() < 10 ? "0" + date.getDay() : date.getDay;
            return date.getFullYear() + "-" + month + "-" + currentDate;
        }
