问题描述：
提琴: http://jsfiddle.net/bnsex/1/
我想使用12小时时钟作为此代码...
I want to use 12 hour clock for this code...
$(document).ready(function() {
setInterval( function() {
var hours = new Date().getHours();
$(".hours, .hour").html(( hours < 10 ? "0" : "" ) + hours);
}, 1000);
});
非常感谢您的帮助:D
Your help is much appreciated :D
答
您可以使用模数%运算符来实现此目的，该运算符可以找到除法运算的其余部分.
You can achieve this using the modulus % operator, which finds the remainder of a division operation.
例如11 % 12和23 % 12都等于11，就像12小时制一样.
For example, 11 % 12 and 23 % 12 both equal 11, like a 12-hour clock would portray.
var hours = new Date().getHours() % 12;
if (hours == 0) {
hours += 12;
}
