json数据的时间格式转换如：/Date(2342561534)/

                     var date = new Date(parseInt(value.replace("/Date(", "").replace(")/", ""), 10));
                     var month = date.getMonth() + 1 < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1;
                     var currentDate = date.getDate() < 10 ? "0" + date.getDate() : date.getDate();
                     return date.getFullYear() + "-" + month + "-" + currentDate;
