Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说js 毫秒转成时分秒毫秒格式[亲测有效],希望能够帮助你!!!。

// 3671520转化成00:00:00,000   =>01:01:11,520    
    formatTime2HMSMs = time =>{
        const millisecond = parseInt(time%1000) 
        let second = 0;
        let totalMinute = 0;
        let minute = 0;
        let hour = 0;
        let result = "";
        const totalSecond = parseInt(time/1000)   // 3671
        if(totalSecond>59){   // 总秒数大于59 需要计算总分钟 数
            second =  parseInt(totalSecond%60)    // 11
            totalMinute =  parseInt(totalSecond/60)  // 61
        }else{
            second = totalSecond
        }
        if(totalMinute>59){
            minute = parseInt(totalMinute%60)   // 1
            hour = parseInt(totalMinute/60)     // 1 
        }else{
            minute =  totalMinute
        }
        if(hour<10){
            result+="0"+hour;
        }else{
            result+=""+hour;
        }
        if(minute<10){
            result+=":0"+minute;
        }else{
            result+=":"+minute;
        }
        if(second<10){
            result+=":0"+second;
        }else{
            result+=":"+second;
        }
        if(millisecond<10){
            result+=",00"+millisecond;
        }else if(millisecond<100){
            result+=",0"+millisecond;
        }else{
            result+=","+millisecond; 
        }
        return result;
    }
