js如何判断时间

const now = new Date();
console.log(now); // 输出当前日期和时间

const timestamp = Date.now(); // 返回当前时间的时间戳（毫秒）
console.log(timestamp);

function isWorkingHours() {
    const now = new Date();
    const hour = now.getHours(); // 获取当前小时（0-23）

    return hour >= 9 && hour < 18;
}

console.log(isWorkingHours() ? "工作时间" : "非工作时间");

function isBetween10And12() {
    const now = new Date();
    const hour = now.getHours();
    const minute = now.getMinutes();

    const currentTimeInMinutes = hour * 60 + minute;
    const startTimeInMinutes = 10 * 60;
    const endTimeInMinutes = 12 * 60;

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

console.log(isBetween10And12() ? "在10点到12点之间" : "不在10点到12点之间");

const now = new Date();
console.log(now.toLocaleString()); // 输出格式化的日期和时间，例如 "2023/10/5 下午3:24:00"

const now = new Date();
const formatter = new Intl.DateTimeFormat('zh-CN', {
    year: 'numeric',
    month: '2-digit',
    day: '2-digit',
    hour: '2-digit',
    minute: '2-digit',
    second: '2-digit'
});

console.log(formatter.format(now)); // 输出格式化的日期和时间，例如 "2023/10/05 15:24:00"
