多项选择测验-单选按钮和功能问题

我正试图使用HTML表单标记中的简单函数和单选按钮创建一个多选测验，但它只允许我在整个测验中选中一个单选按钮，而不是每个问题选中一个。

此外，提交按钮没有激活功能checkAll，我不知道这是因为我试图做一些不可能的事情，还是因为我错过了一些简单的事情。任何帮助都将不胜感激！

代码如下。我只是JavasScript和html以及StackOverflow的新手，所以如果我在这个问题上做错了什么，我很抱歉。

<head>
<script language="javascript">
var score=0;
function checkAll() {
function questioncheckOne(){
    var correctAnswer = document.getElementById("a3")
    if (correctAnswer.checked == true) {
        score++;
        alert("Correct, your score is now " +score)
    }
    else {
            alert("Wrong, your score is now " +score)
    }
};

function questioncheckTwo(){
    var correctAnswer = document.getElementById("b2")
    if (correctAnswer.checked == true) {
        score++;
        alert("Correct, your score is now " +score)
    }
    else {
            alert("Wrong, your score is now " +score)
    }
};

function questioncheckThree(){
    var correctAnswer = document.getElementById("c4")
    if (correctAnswer.checked == true) {
        score++;
        alert("Correct, your score is now " +score)
    }
    else {
            alert("Wrong, your score is now " +score)
    }
};

function questioncheckFour(){
    var correctAnswer = document.getElementById("d3")
    if (correctAnswer.checked == true) {
        score++;
        alert("Correct, your score is now " +score)
    }
    else {
            alert("Wrong, your score is now " +score)
    }
};

function questioncheckFive(){
    var correctAnswer = document.getElementById("e3")
    if (correctAnswer.checked == true) {
        score++;
        alert("Correct, your score is now " +score)
    }
    else {
            alert("Wrong, your score is now " +score)
    }
};
};

您需要使name属性对于每组单选按钮都是唯一的。目前，它们都被命名为radio。

至于checkAll函数，问题是您只是在定义函数，而不是调用它们。在checkAll函数中，实际调用您定义的其他函数：

function checkAll() {
    // existing function definitions here
    questioncheckOne();
    questioncheckTwo();
    // etc
}

选中单选按钮时，将取消选中所有其他同名按钮。在您的情况下，您希望每个问题的收音机都有一个单独的名称（现在，它们都是"收音机"）
