这只是家庭作业的一小部分，但我现在卡住了，不知道该怎么做。整个项目是创建JWplayer，将视频与成绩单相匹配，与成绩单同步突出显示成绩单中的短语，并能够点击短语并让视频跳转到它。我坚持到最后一部分。
$.fn.playerConnect = function(player){
var transcriptElements = this;
player.onTime(function(evt){
return this.click(function(evt){ // where the action happens
var i = 0;
var startTime = parseFloat($(transcriptElements[i]).attr("data-start"));
player.seek(startTime);
});
};
})(jQuery);
这是项目的Html部分。正如您将能够分辨的那样，这些短语被分为两个部分。所以基本上，伪代码是
对于click事件，data-start的返回值， 在视频中寻求价值（player.seek）
