javascript – 使用ajax将php响应发送到div无法正常工作

嗨,我目前正在开展一个项目.当用户提交表单时,它会将响应加载到div而不是加载新页面.我已经查看了与PHP一起在线工作的ajax表单的其他示例,但它并没有帮助我解决我的问题. (我对此很新).

当我单击提交时,不是将响应发布到同一页面并向所选电子邮件地址发送电子邮件,而是将我带到PHP文件并在那里回复响应,但不发送任何电子邮件.

任何人都可以看到这出错的地方？

表格代码：

<form name="contactform" id="contact-form" action="mailer.PHP">

            <input type="text" class="textBox" name="name" value="Name" required="required" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Name';}">

            <input type="text" class="textBox" name="email" value="Email" required="required" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Email';}">

            <textarea name="message" value="Message:" required="required" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Message';}">Message</textarea>

           <input type="submit" value="Send Now">

</form>
                    <div id="response"></div>

Javascript代码：

<script>
 $("#contactform").submit(function(event) 
 {
     /* stop form from submitting normally */
     event.preventDefault();

     /* get some values from elements on the page: */
     var $form = $( this ),
         $submit = $form.find( 'button[type="submit"]' ),
         name_value = $form.find( 'input[name="name"]' ).val(),
         email_value = $form.find( 'input[name="email"]' ).val(),
         message_value = $form.find( 'textarea[name="message"]' ).val(),
         url = $form.attr('action');

     /* Send the data using post */
     var posting = $.post( url, { 
                       name: name_value, 
                       email: email_value, 
                       message: message_value 
                   });

     posting.done(function( data )
     {
         /* Put the results in a div */
         $( "#response" ).html(data);

     });
});
</script>

PHP代码:(我的PHP存储在一个名为mailer.PHP的单独文件中)我试图将PHP $响应变量发回并放入响应div.

<?PHP


    // Get the form fields and remove whitespace.
    $name = $_POST["name"];
    $email = $_POST["email"];
    $message = $_POST["message"];

    $to = "[e-mail]";
    $subject = "New DPS Email from $name";

    // Build the email content.
    $email_content = "Name: $name\n";
    $email_content .= "Email: $email\n\n";
    $email_content .= "Message:\n$message\n";

    // Build the email headers.
    $email_headers = "From: $name <$email>";

    $mailed = (mail($to, $subject, $email_content, $email_headers));

    if( isset($_POST['ajax']) )
    $response = ($mailed) ? "1" : "0";
    else
    $response = ($mailed) ? "<h2>Thank You! Your message has been sent.</h2>" : "<h2>Oops! Something went wrong and we Couldn't send your message.</h2>";

    echo $response; 

?>

在此先感谢您的帮助！

解决方法:

这是你可以做的：
表格代码

<form name="contactform" id="contact-form">
    <!--Your form elements here -->
</form>

javascript代码(使用#contact-form而不是#contactform)

<script>
$("#contact-form").submit(function(event) 
{
 /* stop form from submitting normally */
 event.preventDefault();

 /* get some values from elements on the page: */
 var $form = $( this ),
     $submit = $form.find( 'button[type="submit"]' ),
     name_value = $form.find( 'input[name="name"]' ).val(),
     email_value = $form.find( 'input[name="email"]' ).val(),
     message_value = $form.find( 'textarea[name="message"]' ).val(),
     url = 'your_url_here';

 /* Send the data using post */
 var posting = $.post( url, { 
                   name: name_value, 
                   email: email_value, 
                   message: message_value 
               });

 posting.done(function( data )
 {
     /* Parse JSON */
     var response = JSON.parse(data);
     $("#response").html(response.msg);

    });
 });
</script>

你的PHP代码：

<?PHP


// Get the form fields and remove whitespace.
$name = $_POST["name"];
$email = $_POST["email"];
$message = $_POST["message"];

$to = "[e-mail]";
$subject = "New DPS Email from $name";

// Build the email content.
$email_content = "Name: $name\n";
$email_content .= "Email: $email\n\n";
$email_content .= "Message:\n$message\n";

// Build the email headers.
$email_headers = "From: $name <$email>";

$mailed = mail($to, $subject, $email_content, $email_headers);

if( $mailed )
$response = json_encode(array("status"=>true,"msg"=>"<h2>Thank You! Your message has been sent.</h2>"));
else
$response = json_encode(array("status"=>false,"msg"=>"<h2>Oops! Something went wrong and we Couldn't send your message.</h2>"));

echo $response; 

?>
