我完全是 HTML 和 javascript 的初学者，我需要编写一个由具有以下功能的单选按钮组成的多项选择测验：
1）它应该将所有答案收集到一个数组中。例如，如果用户在第 i 个问题中选择了第三个答案，则数组的第 i 个元素为 3。没有最终分数，也没有正确/错误答案。在测验结束时，我只需要展示答案。
2）它应该一次发布一个问题（每页一个问题）。
SO中已经讨论了一个类似的问题，即如何在javascript中一次出现一个测验问题
并且建议的 JSfiddle 示例似乎是一个很好的起始解决方案，但我不知道如何使用它。我试图在html 文件和html 文件之间插入 javascript<head>和</head>html 代码，但它不起作用。有人可以发布解决我问题的html代码吗？<body></body>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="quiz.js"></script>
</head>

OP评论后更新
将此代码放在页面顶部的脚本标记中
<script>
$(document).ready(function () {
$('div.questions').find('input:radio').prop('checked', false);
});
</script>
或者
<script>
$(document).ready(function () {
$('div.questions').each(function () {
if ($(this).css('display') == 'block') {
$(this).find('input:radio').prop('checked', false);
}
});
});
</script>
