如何格式化HTML5音频&x27；使用Javascript的s currentTime属性

我尝试使用以下等式格式化HTML5 currentTime属性：

var s = parseInt(audio.currentTime % 60);

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

var m=parseInt（（audio.currentTime/60）%60）； duration.innerHTML=m+'：'+s

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

这是可行的，只是我希望秒数1-9显示为：01-:09，而不是当前的：1和：9。如果（m<10）m='0'+m；

if (m < 10) m = '0' + m; 
if (s < 10) s = '0' + s;

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

如果（s<10）s='0'+s；

如果

s

小于10，只需添加一个0即可。之后

var m = parseInt((audio.currentTime / 60) % 60);

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

放

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

if（s<10）{
s='0'+s；
}

代码非常简单。

这可能会对您有所帮助，我使用了：

  function formatTime(seconds) {
    minutes = Math.floor(seconds / 60);
    minutes = (minutes >= 10) ? minutes : "0" + minutes;
    seconds = Math.floor(seconds % 60);
    seconds = (seconds >= 10) ? seconds : "0" + seconds;
    return minutes + ":" + seconds;
  }

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

---

var currentTime=audio.currentTime | 0

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

在TypeScript上：

    var minutes = "0" + Math.floor(currentTime / 60);
    var seconds = "0" + (currentTime - minutes * 60);
    var cur = minutes.substr(-2) + ":" + seconds.substr(-2);

formatTime(seconds: number): string {

    let minutes: any = Math.floor(seconds / 60);
    let secs: any = Math.floor(seconds % 60);

    if (minutes < 10) {
        minutes = '0' + minutes;
    }

    if (secs < 10) {
        secs = '0' + secs;
    }

    return minutes +  ':' + secs;
}

formatTime（秒：数字）：字符串{
让分钟：任意=数学地板（秒/60）；
让秒：任意=数学地板（秒%60）；
如果（分钟<10）{
分钟='0'+分钟；
}
如果（秒<10）{
秒='0'+秒；
}
返回分钟数+'：'+秒；
}
