jquery 判断时间类型

javascript function getTimeType(time) { if ($.isPlainObject(time) && time instanceof Date) { return '日期时间类型'; } else if (typeof time === 'number' && (time.toString().length === 10 || time.toString().length === 13)) { return '时间戳类型'; } else if (typeof time === 'string' && /^(\d{4})-(\d{2})-(\d{2}) (\d{2}):(\d{2}):(\d{2})$/.test(time)) { return '字符串类型'; } else { return '未知类型'; } }
