问题描述

我有大城市名称的按钮。

点击它们，我想在当地获得当地时间。

I have buttons with the names of big cities.
Clicking them, I want to get local time in them.

$('#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

但是如何获得AM或PM？

But how can I get AM or PM ?

推荐答案

请尝试以下代码：

$('#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);
});
