JavaScript测验得分函数

Question

好的，所以我在javascipt中为一个测验做了这个项目，用Javascript，css，html和jquery进行了测试，并且我得到了让得分工作的问题。问题是当结果部分被加载时，在测验结束时获得总数。 1/6，每次我结束测验时，它都会提供相同的数字。这是我到目前为止有：

var answers = "0"; 
function answerTotals() 
{ 

if (document.getElementById("1A").checked = true) answers++; 
else(console.log("answer was incorrect")); 
} 

这部分在页面上显示的结果：

function showScore() 
{ 

document.getElementById("Score").innerHTML = "You Got " + answers + "/6"; 
console.log("Score is displayed."); 
} 

而问题：

<div id="questions1"> 
<h1>Question 1.</h1> 
<br> 
Why are there data types in JavaScript? 
<br> 
<br><input type="radio" name="q1" value="A" id="1A" onchange="question1()">As it helps a computer differentiate between different data. 
<br><input type="radio" name="q1" value="B" id="1B" onchange="question1Wrong1()">There aren't. 
<br><input type="radio" name="q1" value="C" id="1C" onchange="question1Wrong2()">To help it interact with Java. 
<br><input type="radio" name="q1" value="D" id="1D" onchange="question1Wrong3()">To allow it to    complete a task. 
<br> 
<input type="button" value="Next" onclick="nextQuestion();answerTotals()"> 
<br> 
<br> 
<p onclick="hint1()"> 
</div> 

Answer 1

您的值设置为true ，不检查一致性。试试这个

if (document.getElementById("1A").checked === true) answers++;
