如何在javascript中将秒转换为分钟和小时 [英] How to convert seconds to minutes and hours in javascript

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?

推荐答案

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; 
}
