视频时长，时间搓转化成 分秒的格式

//方法一： 时间转化（好用）


 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();
       }

' + min + ':' + sec + '



//方法2：

Sub.timeTransf = function(e, data) {
    var time = e.data('time');
    e.html(formatSeconds(time));

    function formatSeconds(value) {
        var secondTime = parseInt(value);
        var minuteTime = 0;
        var hourTime = 0;
        if (secondTime > 60) {
            minuteTime = parseInt(secondTime / 60);
            secondTime = parseInt(secondTime % 60);
            if (minuteTime > 60) {
                hourTime = parseInt(minuteTime / 60);
                minuteTime = parseInt(minuteTime % 60);
            }
        }
        var result = "" + parseInt(secondTime);
        if (minuteTime > 0) {
            if (minuteTime < 10) {
                result = "0" + parseInt(minuteTime) + ":" + result;
            } else {

            }
