name 'forml' is not defined

The error message you are seeing indicates that you are trying to use a variable or function called "forml" that has not been defined.
To fix this error, you need to define or import the "forml" module in your code before trying to use it. If you are using a third-party library called "forml", make sure it is properly installed and imported in your code.
Alternatively, it could be a typo or a mistake in the variable name. Double-check your code and make sure you are using the correct spelling and syntax.

这段代码定义了一个函数Cin,函数参数为一个指向Books类型的指针abs。
函数的作用是向Books类型的对象中添加课程信息。首先询问要添加几个课程,然后从标准输入流(cin)中读取课程的名称、编号、性质、学分、学时、授课学时和实验学时等信息,并存储到Books类型对象的ClassArray数组中。每次添加成功后,输出提示信息,并将课程信息写入到一个名为"kc.txt"的文件中。
如果要添加的课程数量超过了5个,则输出错误提示信息并暂停程序执行,如果没有超过,则通过循环依次添加每一个课程信息。在循环中,先将Books类型对象的number属性增加1,然后依次从标准输入流中读取课程的各项信息,存储到ClassArray数组中。读取课程学分和课程学时时,调用了函数xiuf来确保输入的是整数。最后,将添加成功的课程信息写入到文件中,并输出提示信息。
总体来说,该函数的作用是实现课程信息的录入和存储。

你的问题是如何用 JavaScript 对表单进行验证?
以下是一个简单的表单验证示例,可以验证用户名、密码、电子邮件、电话和身份证号是否符合指定的格式要求:
```html
<!DOCTYPE html>
<html>
<head>
<title>表单验证</title>
<script>
function validateForm() {
var username = document.getElementById("username").value;
var password1 = document.getElementById("password1").value;
var password2 = document.getElementById("password2").value;
var email = document.getElementById("email").value;
var tel = document.getElementById("tel").value;
var idcard = document.getElementById("idcard").value;
// 验证用户名
if (username == "") {
alert("用户名不能为空");
return false;
}
// 验证密码
if (password1 == "" || password2 == "") {
alert("密码不能为空");
return false;
} else if (password1 != password2) {
alert("两次输入的密码不一致");
return false;
}
// 验证电子邮件
var emailPattern = /^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/;
if (!emailPattern.test(email)) {
alert("电子邮件格式不正确");
return false;
}
// 验证电话
var telPattern = /^1[34578]\d{9}$/;
if (!telPattern.test(tel)) {
alert("电话格式不正确");
return false;
}
// 验证身份证号
var idcardPattern = /^\d{17}[\dX]$/;
if (!idcardPattern.test(idcard)) {
alert("身份证号格式不正确");
return false;
}
return true;
}
</script>
</head>
<body>
<form name="forml" onsubmit="return validateForm();">
<p> 用户名:<input id="username" type="text" size="20">*</p>
<p>用户密码:<input id="password1" type="password" size="20">*</p>
<p>重复密码:<input id="password2" type="password" size="20">*</p>
<p>电子邮件:<input id="email" type="text" size="20">*</p>
<p> 电话:<input id="tel" type="text" size="20">*</p>
<p>身份证号:<input id="idcard" type="text" size="20">*</p>
<p><input type="submit" value="提交">
<input type="reset" value="重置">
</p>
</form>
</body>
</html>
```
在这个示例中,我们使用 JavaScript 的正则表达式来验证电子邮件、电话和身份证号的格式。如果表单验证不通过,会弹出一个警告框,阻止表单提交。如果表单验证通过,就会提交表单。
