Javascript 单击jwplayer的带有成绩单的事件

这只是家庭作业的一小部分，但我现在陷入困境，不知道该做什么。整个项目是创建JWplayer，将视频与成绩单匹配，突出显示成绩单中与视频同步的短语，并能够单击短语并让视频跳转到它。我被最后一部分卡住了

$.fn.playerConnect = function(player){


    var transcriptElements = this;

    player.onTime(function(evt){



    return this.click(function(evt){ // where the action happens
    var i = 0;
    var startTime = parseFloat($(transcriptElements[i]).attr("data-start"));
             player.seek(startTime);

   });
};

})(jQuery);

这是项目的Html部分。如您所知，这些短语分为span。所以基本上，伪代码是

对于click事件，返回数据开始的值， 在视频中查找值（player.seek）

不管我点击哪个跨度，视频只会将我返回到10秒。请帮忙

这是一个可以用作模板的演示-
