Question

我试图贬低类似于Adward的音频文件的期限,我可以认为这一公式是正确的。我搜索了,但找不到我所期待的东西。我确信,这将是某个人的一些容易的 st流点。

这里几乎是我从事以下工作的实例:

http://jsfiddle.net/philbot/tfSTh/。

Basically, if you push play, it will start a timer for the song. Time elapsed works fine, however I m having trouble with the countdown. I can t get the seconds to countdown correctly. Here s the JS for the countdown portion: (please refer to my fiddle for the rest)

// Countdown
audio.addEventListener("timeupdate", function() {
    var timeleft = document.getElementById( timeleft );
    var ml = parseInt((audio.duration / 60 - audio.currentTime / 60) % 60);

    // Here s the incorrect seconds countdown calc
    var sl = parseInt(audio.duration % 60 - audio.currentTime);

    if (sl < 10) {
      timeleft.innerHTML = ml +  :0  + sl;
    }
    else {
      timeleft.innerHTML =  -  + ml +  :  + sl;
    }
}, false);

感谢大家
