当我在javascript中使用"getHour()"方法时，它将显示军事时间格式.我需要它以1-12之间的数字显示小时.有人可以告诉我该怎么做吗?这是我正在使用的代码:

When I use the "getHour()" method in javascript, it displays the military time format. I need it to display the hour in numbers between 1-12 instead. Can anybody tell me how to do this? Here is the code I am using:

function updateclock()
{

    var time = new Date();
    var todisplay = '';

    if (time.getHours() < 10) todisplay += time.getHours();
    else todisplay += time.getHours();

    if (time.getMinutes() < 10) todisplay += ':0' + time.getMinutes();
    else todisplay += ':' + time.getMinutes();

    document.getElementById("clock").innerHTML = todisplay;
}
