如何在javascript中将秒转换为分钟和小时
问题描述:
我有一个存储在变量秒
中的秒数。我想将例如1439秒转换为23分59秒。如果时间大于1小时(例如9432秒),则为2小时37分12秒。
I have a count of seconds stored in variable seconds
. I want to convert for example 1439 seconds to 23 minutes and 59 seconds. And if the time is greater than 1 hour (for example 9432 seconds), to 2 hours, 37 minutes and 12 seconds.
我如何实现这一目标?
我在考虑:
var sec, min, hour;
if(seconds<3600){
var a = Math.floor(seconds/60); //minutes
var b = seconds%60; //seconds
if (b!=1){
sec = "seconds";
}else{
sec = "second";
}
if(a!=1){
min = "minutes";
}else{
min = "minute";
}
$('span').text("You have played "+a+" "+min+" and "+b+" "+sec+".");
}else{
var a = Math.floor(seconds/3600); //hours
var x = seconds%3600;
var b = Math.floor(x/60); //minutes
var c = seconds%60; //seconds
if (c!=1){
sec = "seconds";
}else{
sec = "second";
}
if(b!=1){
min = "minutes";
}else{
min = "minute";
}
if(c!=1){
hour = "hours";
}else{
hour = "hour";
}
$('span').text("You have played "+a+" "+hour+", "+b+" "+min+" and "+c+" "+sec+".");
}
但这是很多代码,必须每秒计算一次。我该怎么收缩呢?
But that's a lot of code, and it has to be calculated each second. How can I shrink this up?

我想你会找到这个解决方案非常有帮助。
I think you would find this solution very helpful.
您可以修改显示格式以满足您的需求 -
You modify the display format to fit your needs with something like this -
function secondsToHms(d) {
d = Number(d);
var h = Math.floor(d / 3600);
var m = Math.floor(d % 3600 / 60);
var s = Math.floor(d % 3600 % 60);
var hDisplay = h > 0 ? h + (h == 1 ? " hour, " : " hours, ") : "";
var mDisplay = m > 0 ? m + (m == 1 ? " minute, " : " minutes, ") : "";
var sDisplay = s > 0 ? s + (s == 1 ? " second" : " seconds") : "";
return hDisplay + mDisplay + sDisplay;
}
