Javascript 基于用户选择的随机MCQ

我创建了一个由20个MCQ问题（在一页中）组成的测验。首先，用户必须选择他/她希望尝试的问题数量。这是我的两个单选按钮：

<p>Choose the number of question you want to attempt at a time</p>
    3 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html')"/><br>
      OR<br>
    5 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html')" />

---

第一步：使用$\u获取参数

<p>Choose the number of question you want to attempt at a time</p>
    3 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html?number=3')"/><br>
      OR<br>
    5 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html?number=5')" />

<p>Choose the number of question you want to attempt at a time</p>
    3 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html?number=3')"/><br>
      OR<br>
    5 Question<input type="radio" name="radiobutton"  onClick="load('expert1.html?number=5')" />

$numberOfQuestions = $_GET['number'];
// ...
