我有以下代码，验证规则无效，请提供任何帮助！网络浏览器无法识别javascript代码，因为似乎没有显示活动的x控件。
<HTML>
<head>
<title>Exam entry</title>
<script lanuage="javascript" type="text/javascript">
var result = true;
function validateForm() {
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 (document.ExamEntry.ExaminationNumber.value=="") {
msg+("You must enter the Examination Number \n");
document.ExamEntry.ExaminationNumber.focus();
document.getElementById('ExaminationNumber').style.color="red";
result false;
}
if(msg==""){
return result;
}
{
alert(msg)
return result;
}
}
</script>
<form>
<input type="radio" name="qualification" value="GCSE">GCSE<br>
<input type="radio" name="qualification" value="AS">AS<br>

请有人帮忙，这让我发疯了！
最佳答案
您在第23和29行缺少'='符号result false;应该是result = false;
提示：您可以在浏览器的开发人员控制台中检查js错误。
更新：好的，当我对其进行测试时，以下工作正常：
<html>
<head>
<title>Exam entry</title>
<script lanuage="javascript" type="text/javascript">
var result = true;
function validateForm() {
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 (document.ExamEntry.ExaminationNumber.value == "") {
msg + ("You must enter the Examination Number \n");
document.ExamEntry.ExaminationNumber.focus();
document.getElementById('ExaminationNumber').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">
