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);
