这是我的backend_contact.php页面编码。
<?php
include 'phpmailer/PHPMailerAutoload.php';
if(isset($_POST['send'])){
$name = $_POST['name'];
$email = $_POST['email'];
$msg = $_POST['message'];
$full_message='<table width="650" border="0" align="center" cellpadding="5" cellspacing="0" bgcolor="#FFFFFF">
<tr>
<td width="584" bgcolor="#FFFFFF"><span class="style3">Parekh Website Contact Form</span></td>
</tr>
<tr>
<td height="45" valign="middle" bgcolor="#FFFFFF">

if(empty($name)){
echo "<script type='text/javascript'>
alert('Please Enter Your Name.')
window.location = '../contact.php';

window.location = '../contact.php';
</script>";
}
elseif(empty($msg)){
echo "<script type='text/javascript'>
alert('Please Enter Your Message.')
window.location = '../contact.php';
</script>";
}
else{
$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';
$mail->Host = 'smtp.sendgrid.net';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "xxxx.in";
$mail->Password = "xxxx";
$mail->setFrom('xxx@xxx.in','xxxx');
$mail->addAddress('xxxx@xxx.in', 'xxxx');
$mail->Subject = 'Website Contact Form';
$mail->msgHTML($full_message);
$mail->AltBody = 'Website Contact Form';
if ($mail->send()){
echo "<script>
alert('Form Submitted successfully.');
window.location.href='../contact.php';

}
}
}
?>

没有任何错误，即所有Mailer Debug代码，因为您已将其设置为
$mail->SMTPDebug = 2;
您应该将Mailer调试设置为关闭，因此不会显示调试代码。
使用下面的代码。
$mail->SMTPDebug = 0

尝试将window.location.href替换为除此之外的window.location，我没有看到任何问题，也关闭了phpmailer调试。
