首先免责声明：我是一位完整的编码新手。事实上，更糟糕的是，我知道足以引起麻烦，但不足以解决或正确解决问题（我正在慢慢学习）。
我正在使用以下代码：https://github.com/jewlofthelotus/SlickQuiz 进行在线测验。 在http://users.jyu.fi/~joahtika/quiz_theses/处查看示例SlickQuiz（不是我的-尚未在线）。
除了一个小问题，我一切都很好。
我的问题很长，并且当您按下检查答案/下一个/后退/完成测验按钮之一时，该窗口不会滚动回到页面顶部（或更具体地说，回到问题文本）的页面太远了）。
我试图在此使用以前问过的问题，但是如果已经回答了这个问题，我很抱歉没有找到答案。
我发现https://github.com/jewlofthelotus/SlickQuiz/blob/master/js/slickQuiz.js中的一些代码看起来像是应该修改的地方：
// Bind "next" buttons
$(_element + ' ' + _nextQuestionBtn).on('click', function(e) {
e.preventDefault();
plugin.method.nextQuestion(this, {callback: plugin.config.animationCallbacks.nextQuestion});
});
我尝试添加各种内容（例如$ .scrollTo（$（'＃myDiv'）或类似内容– https://github.com/jewlofthelotus/SlickQuiz/blob/master/index.html中有一个<div class="quizHeader">看起来很有希望），但结果却多种多样几乎所有的东西什么都不做，或者它们都起作用，但是阻止了按钮的功能。
如果有人能够提供帮助，将不胜感激。我事先表示歉意，但是由于缺乏经验，我可能需要一些帮助才能带我逐步了解各种代码的去向。
