没有IE开发工具栏打开，简单的联系表单不起作用

2018-06-23 12:34:20

我有一个简单的联系表单，适用于除IE以外的所有浏览器。只有当我打开IE的开发者工具条（DT）时，它才能与IE一起工作。由于我不能要求人们按F12，如果他们使用IE浏览器，有人可以向我解释为什么IE是如此痛苦......不喜欢代码？我不能使用开发者工具，因为代码在运行时工作。

成功时的功能：您保持在同一页面上，弹出一条消息，感谢您提交。数据存储在数据库中并发送电子邮件。

没有打开DT的IE：您重定向到.php地址，并且没有任何内容，但结果文本。数据不会存储在数据库中，并且电子邮件会与所有信息一起发送，“评论”部分除外。

当然，它从一开始就用HTML开始......

            var name = $('#name').val();
            var email = $('#email').val();
            var comments = $('#comments').val();

            $.ajax({
                url: 'submit_to_db.php',
                type: 'POST',
                data: 'name=' + name + '&email=' + email + '&comments=' + comments + '&mathq=' + mathq, 


                success: function(result) {

                    $('#mbcontainerresponse').append('<p id="response">' + result + '</p>');
                    $('#loading').fadeOut(500, function() {
                        $(this).remove();
                    });
                console.log(result);
                }
            });

            return false;
        });

      });
    </script>
     </head>
      <body>
<form action="submit_to_db.php" method="post">

当我在没有开发人员工具栏（DT）的情况下在IE中提交时，我将移到实际的.php页面。这应该工作，并在其他浏览器上做，让你在页面上，并从代码的PHP部分更新，这是...

    <?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. "rn" . "Email:  " .$email. "rn" . "Question:  " .$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需要一个调整来运行。我已验证信息已传到.php文件，并得到“谢谢你，我们会很快与你联系！” 不知道该从哪里出发。请帮助，我非常感谢你的时间，并提前谢谢你。

删除console.log调用。如果开发人员工具栏已关闭，则控制台在IE中未定义。
