此单独页面上的编码工作正常。但如果我在下面的表格中包含不起作用
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
</head>
<body>
<form id="signup" method="post">
<input type="email" placeholder="Your e-mail." />
<button>Submit</button>
</form>
<script type="text/javascript">
$('#signup').submit(function() {
validateEmail($('input').val());
return false;
});
function validateEmail(email) {
var re = /^\s*[\w\-\+_]+(\.[\w\-\+_]+)*\@[\w\-\+_]+\.[\w\-\+_]+(\.[\w\-\+_]+)*\s*$/;
if (re.test(email)) {
if (email.indexOf('@metronet.in', email.length - '@metronet.in'.length) !== -1) {
alert('Submission was successful.');
} else {
alert('Email must be a CE e-mail address (your.name@metronet.in).');
}
} else {
alert('Not a valid e-mail address.');
}
}
</script>

我有一个注册页面，其中输入了所有字段，它应该检查电子邮件ID列是否应该包含@ ce.com域，如果用户输入abcd@ce.com它应该继续，否则应该弹出一条消息比如需要输入ce.com域名，因为我已经写了一个脚本，但是对于所有的电子邮件ID，它显示的消息不是有效的电子邮件地址。该部分的任何一个都可以。如果我用表格粘贴相同的代码电子邮件，在其他页面单独提交按钮，它弹出消息，但在此register.php不起作用

您不想爆炸电子邮件并检查它是否包含您想要的内容，
$explode = explode("@", $email);
if($explode[1] == 'c-e.com'){
//Email is valid
}else{
//Email is not valid
}
答案 1 :(得分：0)
您可以通过以下方式执行此操作：
function validateEmail($email)
{
// Check E-mail address is valid
if (!preg_match('/^([a-z0-9\+\_\-\.]+)@([a-z0-9\+\_\-\.]{2,})(\.[a-z]{2,4})$/i', $email)) return false;
// Check for specific domain(s)
$SpecificDomains = array('c-e.com','gmail.com','example.com');
list(, $email_domain) = explode('@', $email, 2);
return !in_array($email_domain, $SpecificDomains);
}
