我有一个简单的联系人表单，它适用于除IE之外的所有浏览器。只有当我打开IE的开发者工具栏（DT）时，它才能与IE一起使用。既然我不能要求人们在使用IE时按F12，有人能向我解释为什么IE如此痛苦吗。。。不喜欢这个代码吗？我不能使用开发人员工具，因为代码在运行时可以工作。
成功后的作用：您停留在同一页面上，会弹出一条消息，感谢您的提交。数据存储在数据库中，并发送电子邮件。
What IE without DT open:您重定向到.php地址，除了结果文本什么都没有。数据没有存储在数据库中，并且会发送一封包含所有信息的电子邮件，"注释"部分除外。
当然，它是从HTML开始的，一开始有一点JavaScript。。。

当我在没有开发者工具栏（DT）的IE中提交时，我会移动到实际的.php页面。这应该在其他浏览器上起作用，就像让你留在页面上并从代码的php部分更新一样，这就是…
<?php
include("dogspw/dogs.inc");
$cxn = mysqli_connect($host,$user,$passwrd,$hotel) or die ("couldn't connect to server");
$query = "INSERT into commentsa(name, email, comments, mathq) VALUES (?, ?, ?, ?)";
if ($_POST['mathq']==12) {
$stmt = $cxn->stmt_init();
echo $_POST['name']."<br />";
echo $_POST['email']."<br />";
echo $_POST['comments']."<br />";
echo $_POST['mathq']."<br />";
if($stmt->prepare($query)) {
$stmt->bind_param('ssss', $_POST['name'], $_POST['email'], $_POST['comments'], $_POST['mathq']);
$stmt->execute();
}
if($stmt) {
echo "Thank you. We'll be in touch with you shortly!";
} else {
echo "There was a problem. Please try again later.";
}
echo "...And thanks for answering the question correctly!";
}
else {
echo "Did you answer the math question? Your comment was not sent.";
}
//setup email
$to='john@smith.com';
$subject='Question from smith.com';
$number=$_POST['mathq'];
$name=$_POST['name'];
$email=$_POST['email'];
$questiona=$_POST['comments'];
$message="Name: ".$name. "'r'n" . "Email: " .$email. "'r'n" . "Question: " .$questiona;
if ($number==12){
mail($to,$subject,$message);
echo '<br /><span style="background-color:#dfe0fc">An email has been sent to me, as well.<br />Just in case...<a href="http://www.smith.com"><span style="text-decoration: none">Go back to Smith</span></span></a>';
}
else
{
echo '<br /><span style="background-color:#dfe0fc">An email was not sent, either.<br />
Just in case...<a href="http://www.smith.com"><span style="text-decoration: none">Go back to smith</span></span></a>';
}
?>
我已经走过了每一步，显然不知道IE需要一个调整才能运行。我已经验证了该信息是否已进入.php文件，并得到了"谢谢。我们很快就会与您联系！"的回复，不知道从这里开始该怎么办。请帮忙，我非常感谢您抽出时间，并提前感谢您。
删除console.log调用。控制台在IE中是未定义的，如果开发者工具栏是关闭的。
