视频时长，时间搓转化成 分秒的格式

//方法一： 时间转化
Sub.timeTransf = function(e, data) {
    var time = e.data('time');
    e.html(formatSeconds(time));

    function formatSeconds(value) {
        var secondTime = parseInt(value);

Sub.timeTransf（290）----> 04:50






//方法2：

 var min = Math.floor(+data[x].iTime / 60);
       if (min.toString().length < 2) {
            min = '0' + min.toString();
        }
       var sec = +data[x].iTime % 60;
       if (sec.toString().length < 2) {
            sec = '0' + sec.toString();
       }

<i>' + min + ':' + sec + '</i>
