检查特定日期的时间功能

Question

I have the following time function that I use to output if the business is open or closed. The way I have it coded works fine for normal business weeks. What I am wanting to do is program it for holidays, such as Christmas, 4th of July, etc that are always on the same day, so the output shows we are closed.

How would I program in the fixed holidays?

function timeNow() {

    //Get time
    var d = new Date(),
    h = ('0' + d.getHours()).slice(-2),
    m = ('0' + d.getMinutes()).slice(-2);

    //Get Day
    new Date().getDay();
    var day = new Date().getDay();
    console.log(day);
    var operateDay = '';
    if (day >= 1 && day <= 5) {
        operateDay = true;
    } else if (day < 1 || day > 5) {
        operateDay = false;
    }

    // Checking time range
    var operatingTime = ((h >= 8 && h < 17) || (h === 8 && m == 0));
    var closedTime = (h >= 17 || h <= 8);
    var operateStatus = '';

    if ((operatingTime) && (operateDay = true)) {
        operateStatus = 'Our office is currently open';
        $('#closedWrap').addClass('block');
        $('#operationStatus').addClass('open');
    } else if (closedTime) {
        operateStatus = 'Our office is currently closed';
        $('#closedWrap').addClass('block');
        $('#operationStatus').addClass('closed');
    } else if (operateDay = false) {
        operateStatus = 'Our office is currently closed';
        $('#closedWrap').addClass('block');
        $('#operationStatus').addClass('closed');
    }

    return operateStatus;
}
var operation = timeNow();
$('#operationStatus').html(operation);

I've modified your original function and created an initial version , that handles a custom, easily "configurable", human-readable list of specific holidays.

 /** * Returns the office's open/closed state. * * @param {Date} [time] - A custom Date object to override the current time. * @returns {string} The state of the office (open or closed). */ function timeNow(time) { // Holidays - month-day format, it's adjusted for human-readability, so // January is 1, February is 2 ... December is 12 var holidays = [ '01-01', // New Year's Day '07-04', // Independence Day, '11-11', // Veterans Day '12-25', // Chirstmas '12-31', // New Year's Eve ]; // Possibility of overriding the current date, if needed time = time || new Date(); // Get time var d = time, h = ('0' + d.getHours()).slice(-2), m = ('0' + d.getMinutes()).slice(-2); // Get day var day = time.getDay(); var operateDay = ''; if (day >= 1 && day <= 5) { operateDay = true; } else if (day < 1 || day > 5) { operateDay = false; } // Checking time range var operatingTime = ((h >= 8 && h < 17) || (h === 8 && m == 0)); var closedTime = (h >= 17 || h <= 8); var operateStatus = ''; // Check against holidays if the store is seemingly open // Since in JavaScipt's built-in Date object, January is 0, February is 1 ... December is 11, // to be humanly usable, add 1 to it, hence the name "adjusted" var adjustedMonth = time.getMonth() + 1; var dayOfMonth = time.getDate(); if (operatingTime) { for (var i = 0, len = holidays.length, holiday, holidayMonth, holidayDay; i < len; i++) { // Process the specific holiday month-date format holiday = holidays[i].split('-'); holidayMonth = parseInt(holiday[0], 10); holidayDay = parseInt(holiday[1], 10); // Check, whether today is a holiday ... if (adjustedMonth === holidayMonth && dayOfMonth === holidayDay) { // ...and if it is, then ...Hooray! Hooray! It's a Holi-Holiday operatingTime = false; closedTime = true; break; } } } if ((operatingTime) && (operateDay = true)) { operateStatus = 'Our office is currently open'; $('#closedWrap').addClass('block'); $('#operationStatus').addClass('open'); } else if (closedTime) { operateStatus = 'Our office is currently closed'; $('#closedWrap').addClass('block'); $('#operationStatus').addClass('closed'); } else if (operateDay = false) { operateStatus = 'Our office is currently closed'; $('#closedWrap').addClass('block'); $('#operationStatus').addClass('closed'); } return operateStatus; } // Testing var shouldBeOpen = [ '2018-06-25', '2018-06-26', '2018-06-27', '2018-06-28', '2018-06-29' ]; var shouldBeClosed = [ '2018-01-01', '2018-07-04', '2018-11-11', '2018-12-25', '2018-12-31', '2019-01-01' ]; var STATUS_OPEN = 'Our office is currently open'; var STATUS_CLOSED = 'Our office is currently closed'; // converts a human-readable year-month-day to UTC date function strToUtcDate(string) { var parts = string.split('-'); var year = parts[0]; var month = parts[1]; var day = parts[2]; return new Date(Date.UTC(year, month - 1, day, 12, 0, 0)); } shouldBeOpen.forEach(function (string) { var date = strToUtcDate(string); var status = timeNow(date); if (status === STATUS_OPEN) { console.log('opened, as it should on:', date); } else { console.log('closed, BUT IT SHOULD NOT ON:', date); } }); shouldBeClosed.forEach(function (string) { var date = strToUtcDate(string); var status = timeNow(date); if (status === STATUS_CLOSED) { console.log('closed, as it should on:', date); } else { console.log('opened, BUT IT SHOULD NOT ON:', date); } });
