以 12 小时格式（上午 9 点至下午 6 点）而非 24 小时显示营业时间

Question

我的目标是显示我的营业时间并指示我们何时关闭。

在codepen 上查看我想要的示例。但这是 24 小时格式。我需要帮助将 javascript 转换为以 12 小时格式显示日期。

以下是显示 24 小时营业时间的 javascript。

jQuery(document).ready(function($){

        var currentDate = new Date();
        var weekday = [];
        weekday[0] = "Sunday";
        weekday[1] = "Monday";
        weekday[2] = "Tuesday";
        weekday[3] = "Wednesday";
        weekday[4] = "Thursday";
        weekday[5] = "Friday";
        weekday[6] = "Saturday";

        var currentDay = weekday[currentDate.getDay()];

        var currentTimeHours = currentDate.getHours();
        currentTimeHours = currentTimeHours < 10 ? "0" + currentTimeHours : currentTimeHours;
        var currentTimeMinutes = currentDate.getMinutes();
        var timeNow = currentTimeHours + "" + currentTimeMinutes;

        var currentDayID = "#" + currentDay; //gets todays weekday and turns it into id
        $(currentDayID).toggleClass("today"); //this works at hightlighting today

        var openTimeSplit = $(currentDayID).children('.opens').text().split(":");

        var openTimeHours = openTimeSplit[0];
        openTimeHours = openTimeHours < 10 ? "0" + openTimeHours : openTimeHours;

        var openTimeMinutes = openTimeSplit[1];
        var openTimex = openTimeSplit[0] + openTimeSplit[1];

        var closeTimeSplit = $(currentDayID).children('.closes').text().split(":");

        var closeTimeHours = closeTimeSplit[0];
        closeTimeHours = closeTimeHours < 10 ? "0" + closeTimeHours : closeTimeHours;

        var closeTimeMinutes = closeTimeSplit[1];
        var closeTimex = closeTimeSplit[0] + closeTimeSplit[1];

        if (timeNow >= openTimex && timeNow <= closeTimex) {
            $(".openorclosed").toggleClass("open");
        } else {
            $(".openorclosed").toggleClass("closed");
        }
});

提前感谢您的帮助和时间！

var currentTimeHours = currentDate.getHours();
currentTimeHours = currentTimeHours < 10 ? "0" + currentTimeHours : currentTimeHours;
var currentTimeMinutes = currentDate.getMinutes();
var timeNow = currentTimeHours + "" + currentTimeMinutes;


	Replace the above code by

var currentTimeHours = currentDate.getHours();
var currentTimeMinutes = currentDate.getMinutes();
var timeNow = currentTimeHours % 12 + ':' + currentTimeMinutes + ':'+ (currentTimeHours < 12 ? 'AM':'PM');
