大约24小时12个小时

Question

我想将我的时间改为12小时而不是24小时。

这是我的代码：

$(document).ready(function() {
    var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
    var dayNames = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
    var newDate = new Date();
    newDate.setDate(newDate.getDate());
    $('#Date').html(dayNames[newDate.getDay()] + " " + newDate.getDate() + ' ' + monthNames[newDate.getMonth()] + ' ' + newDate.getFullYear());
    setInterval(function() {
        var seconds = new Date().getSeconds();
        $("#sec").html((seconds < 10 ? "0" : "") + seconds);
    }, 1000);
    setInterval(function() {
        var minutes = new Date().getMinutes();
        $("#min").html((minutes < 10 ? "0" : "") + minutes);
    }, 1000);
    setInterval(function() {
        var hours = new Date().getHours();
        $("#hours").html((hours < 10 ? "0" : "") + hours);
    }, 1000);
});

newHours = (oldHours) % 12
if (newHours == 0) {
    newHours = 12;
