我创建了一个时间函数来计算媒体播放的时间。它不显示任何前导零。我怎样才能让它显示任何前导零?
function converttoTime(timeInSeconds)
{
var minutes = Math.round(Math.floor(timeInSeconds / 60));
var seconds = Math.round(timeInSeconds - minutes * 60);
//var hours = Math.round(Math.floor(timeInSeconds / 3600));
//time = time - hours * 3600;
var time=minutes+':'+seconds;
return time;
}
