我是 Javascript 新手，遇到了问题。我有一个 Javascript 文件，我已链接到一个 HTML 文件，当我仅将它用于一个功能时，它工作正常，但现在我添加了第二个极其相似的功能，它已停止工作，我已经对其进行了多次搜索，但无法确定它为什么会停止工作。我的 HTML 文件如下。

<head>
<title>Programming Aptitude Test-Question One</title>
<script type="text/javascript" src="AnswerStorage.js"></script>
</head>

<body>
<h1>Question One</h1>

<ul>
    <li>a=10</li>
    <li>b=20</li>
    <li>a=b</li>
    <li>b=a</li>
    <li>What is the value of a?</li>
    <li>What is the value of b?</li>
</ul>

<p>Please enter your answer in the form "a=?, b=?", press submit only once when you are happy with your answer and click "next question" to go to the next page</p>

<p>Enter your answer:
    <input type="text" id="firstAnswer" />
</p>

<p>
    <input type="button" id="btnSubmit" value="Submit" />
</p>

<h1>Question Two</h1>

<p>What is a word to describe "walking cautiously"?</p>

<p>Enter your answer:
    <input type="text" id="redundantAnswer" />
</p>

<p>
    <input type="button" id="btnRedundant" value="Submit" />
</p>

<h1>Question Three</h1>

<p>Writ down as many words as you can associate with the word "Career."</p>

<p>Enter your answer:
    <input type="text" id="redundantAnswer" />
</p>

<p>
    <input type="button" id="btnRedundant" value="Submit" />
</p>

<h1>Question Four</h1>

<ul>
    <li>a=5</li>
    <li>b=6</li>
    <li>a=b</li>
    <li>b=a</li>
    <li>What is the value of a?</li>
    <li>What is the value of b?</li>
</ul>

<p>Please enter your answer in the form "a=?, b=?", press submit only once when you are happy with your answer and click "next question" to go to the next page</p>

<p>Enter your answer:
    <input type="text" id="secondAnswer" />
</p>

<p>
    <input type="button" id="secondButton" value="Submit" onclick=(secondCheck()) />
</p>



<a href="Question2.html">Next Question</a>

<p id="result"></p>

我的Javascript文件如下，但我的数组没有打印，因此我无法知道元素是否被添加到其中

var answers = [];
var result = document.getElementById("result");


function init() {
var myButton = document.getElementById("btnSubmit");
myButton.onclick = firstCheck;

}

onload = init;


function firstCheck()

{

var theFirstAnswer = document.getElementById("firstAnswer").value.toLowerCase();
var message = "";


var success = false;

if (newName == "")

{

    alert("Please, enter an answer");

    return false;

}

if (theFirstAnswer == "a=0, b=20") {
    answers.push("m1");
    answers.push("s1");

    }



    if (success)

        answers.push(theSecondAnswer);

    }


    result.innerHTML += "<br />" + answers.sort();

}

很抱歉这可能是一个明显的错误，感谢你们花时间查看此问题。

最佳答案

我认为 } 丢失了

if (theSecondAnswer == "a=7, b=9, c=17") {
    answers.push("m5");
    answers.push("s2");
} // <====  This is missing

您可以使用在线工具，如 jsbeautifier.org格式化您的文档，它们还有助于识别错误
