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。

这是普通中等教育证书计算机课程。我不必修复它，但我不知道在基本代码不起作用的情况下，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>

您的代码有几个语法错误。我已经把它去掉了。这是小提琴链接
