将以下 JSON 返回值从 24 小时格式转换为 12 小时格式的最佳方法是什么?下午?日期应该保持不变 - 时间是唯一需要格式化的东西.
What is the best way to convert the following JSON returned value from a 24-hour format to 12-hour format w/ AM & PM? The date should stay the same - the time is the only thing that needs formatting.
February 04, 2011 19:00:00
附:如果这样做更容易,请使用 jQuery!也更喜欢简单的函数/代码,而不是使用 Date.js.
P.S. Using jQuery if that makes it any easier! Would also prefer a simple function/code and not use Date.js.
更新 2: 没有秒选项
更新: 中午后修正,测试:http://jsfiddle.net/aorcsik/xbtjE/
我为此创建了这个函数:
I created this function to do this:
function formatDate(date) {
var d = new Date(date);
var hh = d.getHours();
var m = d.getMinutes();
var s = d.getSeconds();
var dd = "AM";
var h = hh;
if (h >= 12) {
h = hh - 12;
dd = "PM";
}
if (h == 0) {
h = 12;
}
m = m < 10 ? "0" + m : m;
s = s < 10 ? "0" + s : s;
/* if you want 2 digit hours:
h = h<10?"0"+h:h; */
var pattern = new RegExp("0?" + hh + ":" + m + ":" + s);
var replacement = h + ":" + m;
/* if you want to add seconds
replacement += ":"+s; */
replacement += " " + dd;
return date.replace(pattern, replacement);
}
alert(formatDate("February 04, 2011 12:00:00"));
