我试图在javascript中使用gethours()方法,但它不断返回军事时间。有人可以帮我修理它,以便显示时钟时间吗? (1-12)。非常感谢你!
// Reroute from the conf.js script
var chat = $( '.chat-output' ),
message = function ( message, userId ) {
var dt = new Date(),
time = dt.getHours() + ":" + dt.getMinutes(); // + ":" + dt.getSeconds();
return $( '<div class="chat-message color-' + users[userId] + '">' +
'<div class="chat-id color-' + users[userId] + '"></div>' +
'<div class="chat-user-message">' + message + '</div>' +
'<div class="chat-time">' + time + '</div>' +
'</div>' );
},
addText = function ( text ) {
// log.innerHTML += text;
// log.scrollTop = log.scrollHeight;
console.log( text );
},
addRemoteText = function ( userId, text ) {
// addText( '[' + userId + ']: ' + text+'<br>' );
chat.append( message( text, userId ) );
chat.scrollTop( chat.get( 0 ).scrollHeight );
};

这样的东西?
var dt = new Date();
var hours = dt.getHours();
var ampm = hours > 11 ? 'PM' : 'AM';
if (hours > 12) {
hours -= 12;
} else if (hours === 0) {
hours = 12;
}
var time = hours + ":" + dt.getMinutes() + ' ' + ampm;
答案 1 :(得分:0)
function ampm(date){
var dt= date || new Date,
h= dt.getHours(),
m= dt.getMinutes(),
s= dt.getSeconds(),
ampm;
if(h>12){
h-= 12;
ampm= (h%12)? ' PM': ' AM';
}
else ampm= (h%12)? ' AM': ' PM';
m= m<10? '0'+m: m;
s= s<10? '0'+s: s;
return [h, m, s].join(':')+ampm;
}
<强> AMPM()强>
/* returned value: (String)

以下是以12小时格式格式化时间的另一个版本:
// Returns formatted time for given Date object, or
// current system time if d is falsey.
function getTime(d) {
d = d || new Date();
var hrs = d.getHours();
var pad = function(n){return (n<10?'0':'')+ +n};
return pad(hrs%12 || 12) + ':' + pad(d.getMinutes()) + ' ' + (hrs<12? 'AM':'PM');
}
console.log(getTime(new Date(2014,2,24, 0, 5))); // 12:05 AM
console.log(getTime(new Date(2014,2,24,10,25))); // 10:25 AM
console.log(getTime(new Date(2014,2,24,20,15))); // 08:15 PM
请注意,在许多情况下,首选24小时是为了避免异常情况,例如凌晨12:00(实际上既不是上午或下午),也就是凌晨00:00凌晨01:00之前。
