js 规则校验精确到时分

function validateTime(timeString) {
    // 正则表达式匹配 HH:mm 格式
    const timePattern = /^([01]?[0-9]|2[0-3]):[0-5][0-9]$/;
    if (!timePattern.test(timeString)) {
        return false;
    }
    return true;
}

// 使用示例
console.log(validateTime("12:34")); // true
console.log(validateTime("25:00")); // false
console.log(validateTime("12:60")); // false

function validateTimeInRange(timeString, startTime, endTime) {
    const timePattern = /^([01]?[0-9]|2[0-3]):[0-5][0-9]$/;
    if (!timePattern.test(timeString)) {
        return false;
    }

    const [startHour, startMinute] = startTime.split(':').map(Number);
    const [endHour, endMinute] = endTime.split(':').map(Number);
    const [hour, minute] = timeString.split(':').map(Number);

    const inputTime = hour * 60 + minute;
    const startTimeInMinutes = startHour * 60 + startMinute;
    const endTimeInMinutes = endHour * 60 + endMinute;

    return inputTime >= startTimeInMinutes && inputTime <= endTimeInMinutes;
}

// 使用示例
console.log(validateTimeInRange("12:34", "09:00", "17:00")); // true
console.log(validateTimeInRange("20:00", "09:00", "17:00")); // false
