JavaScript中怎么将24小时制转换为12小时制？

JavaScript中怎么将24小时制转换为12小时制？

代码如下：
window.onload = showTheTime;
function showTheTime() {
var now = new Date(); document.getElementById("showTime").innerHTML =
showTheHours(now.getHours()) +
→showZeroFilled(now.getMinutes()) + showZeroFilled
(now.getSeconds()) + showAmPm();
setTimeout(showTheTime,1000);

function showTheHours(theHour) {
if (show24Hour() || (theHour > 0 && theHour < 13)) {
return theHour;
}
if (theHour = = 0) {
return 12;
}
return theHour-12;
}

function showZeroFilled(inValue) {
if (inValue > 9) {
return ":" + inValue;
}
return ":0" + inValue;
} function show24Hour() {
return (document.getElementById ("show24").checked);
}

function showAmPm() {
if (show24Hour()) {
return "";
}
if ((now.getHours() < 12)) {
return " AM";
}
return " PM";
}
}

大于12减去12不就是了

时间字母大写改成小写试试

(new Date).getHours()%12

如果不希望12:00变成00:00就再加一个等于0的时候+12
