手动触发scroll之后设置scrollTop值无效

Question

手动触发scroll之后设置scrollTop值无效，需要手动点击一下才页面才会滚动，有人遇到过吗？怎么解决的，贴出代码！

//topArr 是一个数组，每个div的getBoundingClientRect().top;

_this.videoPlayer.on('playing',function(){

_this.videoPlayer.setVideoMute(true);

$section.parent().scrollTop(0);

$section.find('.caption-detail').removeClass('location');

var $clickSecion = $section.eq(0);

var curIndex = -1;

timer = setInterval(function(){

  var ct = _this.videoPlayer.getVideoCurrentTime();   

  timeArr.forEach(function(item,index){

    if(ct>=item.startTime && ct< item.endTime){

      if(curIndex != index){

        $clickSecion = $section.eq(index);

        var st = $section.get(index).getBoundingClientRect();

        $section.find('.caption-detail').removeClass('location');

        $clickSecion.find('.caption-detail').addClass('location');

        $section.parent().animate({scrollTop: topArr[index]-topArr[0]},100,function(){

          $section.parent().bind('scroll');

        });

        curIndex = index;   

      }

      

    }

  });

},100);
