代码非常简单。但这是我做的第一件事，我根本不明白我做错了什么。这也是直接来自 OCR 的原始代码。

这是 GCSE 计算课程。我不必修复它，但我不知道在基本代码不工作的情况下我应该如何测试我要添加的东西。

<head>
    <title>Exam entry</title>
    <script language="javascript" type="text/javascript">
        function validateForm(document) {
            var result = true;
            var msg = "";
            if (document.ExamEntry.name.value == "") {
                msg += "You must enter your name \n";
                document.ExamEntry.name.focus();
                document.getElementById(‘name’).style.color = "red";
                result = false;
            }
            if (document.ExamEntry.subject.value == "") {
                msg += "You must enter the subject \n";
                document.ExamEntry.subject.focus();
                document.getElementById(‘subject’).style.color = "red";
                result = false;
            }
            if (msg == "") {
                return result;
            } {
                alert(msg)
                return result;
            }
        }
    </script>
</head>
<body>
     <h1>Exam Entry Form</h1>

    <form name="ExamEntry" method="post" action="success.html">
        <table width="50%" border="0">
            <tr>
                <td id="name">Name</td>
                <td>
                    <input type="text" name="name" />
                </td>
            </tr>
            <tr>
                <td id="subject">Subject</td>
                <td>
                    <input type="text" name="subject" />
                </td>
            </tr>
            <tr>
                <td>
                    <input type="submit" name="Submit" value="Submit" onclick= return "validateForm()";  />
                </td>
                <td>
                    <input type="reset" name="Reset" value="Reset" />

您的代码有几个语法错误。我已经删除了。这是小提琴链接

<h1>Exam Entry Form</h1>
    <form name="ExamEntry" method="post" action="success.html">
        <table width="50%" border="0">
            <tr>
                <td id="name">Name</td>
                <td>

                </td>
            </tr>
            <tr>
                <td id="subject">Subject</td>
                <td>
                    <input type="text" name="subject" />
