How to get AM or PM?
提问by qadenza
I have buttons with the names of big cities.
Clicking them, I want to get local time in them.
我有带有大城市名称的按钮。
单击它们，我想在其中获取当地时间。
$('#btnToronto').click(function () {
var hours = new Date().getHours();
var hours = hours-2; //this is the distance from my local time
alert ('Toronto time: ' + hours + ' h'); //this works correctly
});
But how can I get AM or PM ?

Try below code:
试试下面的代码：
$('#btnToronto').click(function () {
var hours = new Date().getHours();
var hours = (hours+24-2)%24;
var mid='am';
if(hours==0){ //At 00 hours we need to show 12 am
hours=12;
}
else if(hours>12)
{
hours=hours%12;
mid='pm';
}
alert ('Toronto time: ' + hours + mid);
});

You should just be able to check if hours is greater than 12.
您应该能够检查小时是否大于 12。
var ampm = (hours >= 12) ? "PM" : "AM";
But have you considered the case where the hour is less than 2 before you subtract 2? You'd end up with a negative number for your hour.
但是你有没有考虑过减2之前小时小于2的情况？你最终会得到一个负数。

You can use like this,
你可以这样使用，
var dt = new Date();
var h = dt.getHours(), m = dt.getMinutes();
var _time = (h > 12) ? (h-12 + ':' + m +' PM') : (h + ':' + m +' AM');
Hopes this will be better with minutes too.
希望这也会在几分钟内变得更好。

使用 date.js
<script type="text/javascript" src="http://www.datejs.com/build/date.js"></script>
you can write like this
你可以这样写
new Date().toString("hh:mm tt")

very interesting post. in a function that take a date in parameter it can appear like that :
非常有趣的帖子。在参数中采用日期的函数中，它可能如下所示：
function hourwithAMPM(dateInput) {
var d = new Date(dateInput);
var ampm = (d.getHours() >= 12) ? "PM" : "AM";
var hours = (d.getHours() >= 12) ? d.getHours()-12 : d.getHours();
return hours+' : '+d.getMinutes()+' '+ampm;
}

If hoursis less than 12, it's the a.m..
如果hours小于12，则是am。
var hours = new Date().getHours(), // this is local hours, may want getUTCHours()
am;
// adjust for timezone
hours = (hours + 24 - 2) % 24;
// get am/pm
am = hours < 12 ? 'a.m.' : 'p.m.';
// convert to 12-hour style
hours = (hours % 12) || 12;
Now, for me as you didn't use getUTCHours, it is currently 2 hours after
现在，对我来说，因为你没有使用getUTCHours，现在是 2 小时后
hours + ' ' + am; // "6 p.m."

尝试这个：
h = h > 12 ? h-12 +'PM' : h +'AM';

The best way without extensions and complex coding:
没有扩展和复杂编码的最佳方式：
date.toLocaleString([], { hour12: true});
How do you display javascript datetime in 12 hour AM/PM format?

var now = new Date();
var hours = now.getHours();
var minutes = now.getMinutes();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12;
minutes = minutes < 10 ? '0' + minutes : minutes;
var timewithampm = hours + ':' + minutes + ' ' + ampm;
return timewithampm;

var dt = new Date();
var h = dt.getHours(),
m = dt.getMinutes();
var time;
if (h == 12) {
time = h + ":" + m + " PM";
} else {
time = h > 12 ? h - 12 + ":" + m + " PM" : h + ":" + m + " AM";
}
//var time = h > 12 ? h - 12 + ":" + m + " PM" : h + ":" + m + " AM";
console.log(`CURRENT TIME IS ${time}`);
This will work for everytime,
这将适用于每次，
