javascript毫秒分析時間（分鐘：秒）

Question

如何解析給定的毫秒數（例如125230.41294642858）爲時間格式，如：minutes:seconds？

Answer 1

var ms = 125230.41294642858, 
    min = 0|(ms/1000/60), 
    sec = 0|(ms/1000) % 60; 

alert(min + ':' + sec); 

Answer 2

請嘗試以下

var num = Number(theTextValue); 
var seconds = Math.floor(num/1000); 
var minutes = Math.floor(seconds/60); 
var seconds = seconds - (minutes * 60); 
var format = minutes + ':' + seconds 

Answer 3

Number.prototype.toTime = function(){ 
    var self = this/1000; 
    var min = (self) << 0; 
    var sec = (self*60) % 60; 
    if (sec == 0) sec = '00'; 

    return min + ':' + sec 
}; 


var ms = (new Number('250')).toTime(); 
console.log(ms); 
=> '0:15' 

var ms = (new Number('10500')).toTime(); 
console.log(ms); 
=> '10:30' 

Answer 4

即使moment.js不提供這樣的功能，如果你來到這裏，你已經在使用moment.js，試試這個：

function getFormattedMs(ms) { 
    var duration = moment.duration(ms); 
    return moment.utc(duration.asMilliseconds()).format("mm:ss"); 
} 

這個解決方法是在Issue中引入的。
