使用Ajax和jQuery发送邮件(邮件到php Post方法)

Question

我通过执行Php函数从我的html页面发送邮件,我的index.html:

  <form method="POST" action="sendmail.php" >
 <input type="text" name="sender_name" placeholder="Name" required="">
 <input type="text" name="sender_email" placeholder="Email" required="">
 <input type="text" name="subject" placeholder="Subject" required="">
 <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">

    </form>

我的sendmail.php:

<?php
if($_POST['send'] == 'SEND'){

$to      = 'queries@mydomain.com';
$subject = $_POST['subject']; 
$message = $_POST['message']; 
$headers = "From: ".$_POST['sender_nam??e?']." <".$_POST['sender_em??ail??'].">\r\n"; $headers = "Reply-To: ".$_POST['sender_ema??il??']."\r\n"; 
$headers = "Content-type: text/html; charset=iso-8859-1\r\n";
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
}
?>

以上工作正常,但它也离开当前页面我想在当前页面执行上述方法,并根据这个问题和这个问题

我必须使用Ajax和jQuery？到目前为止我对他们一无所知我有这个:

////in my index.html
<button type="button">send mail</button>
<p></p>
<script type="text/javascript">



    $(document).ready(function(){
        $("button").click(function(){

            $.ajax({
                type: 'POST',
                url: 'sendmail.php',
                success: function(data) {
                    alert(data)
                    $("l").text(data);

                }
            });
   });
});
</script>

我知道上面的不正确&它不工作(目前它在弹出窗口中显示sendmail.php的文本)我怎样才能使它工作,以便我可以执行sendmail.php ???

更新:

的index.html

    <form method="POST" id="myForm" action="sendmail.php">
  <input type="text" name="sender_name" placeholder="Name" required="">
  <input type="text" name="sender_email" placeholder="Email" required="">
  <input type="text" name="subject" placeholder="Subject" required="">
  <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">
</form>



</div>
<script type="text/javascript">


  $(document).ready(function(){
        $("#myForm").on('submit', function(){
            var formData = $(this).serialize();
            $.ajax({
                type: 'POST',
                url: 'sendmail.php',
                data: formData,
                success: function(response.success) {
                    alert(response.success)
                    $("l").text(response.success);

                }
            });
   });
</script>
    `

以下应该适合您使用.on('submit'和.serialize()

HTML

<form method="POST" id="myForm" action="sendmail.php">
  <input type="text" name="sender_name" placeholder="Name" required="">
  <input type="text" name="sender_email" placeholder="Email" required="">
  <input type="text" name="subject" placeholder="Subject" required="">
  <textarea placeholder="Message" name="message" required=""></textarea>
  <input type="submit" name="send" value="SEND">
</form>

JS

$(document).ready(function() {
    $("#myForm").on('submit', function(event) {
        event.preventDefault(); 
        var formData = $(this).serialize();
        $.ajax({
            type: 'POST',
            url: 'sendmail.php',
            dataType: "json",
            data: formData,
            success: function(response) { 
                alert(response.success); 
            },
            error: function(xhr, status, error){
                console.log(xhr); 
            }
        });
    });
});

PHP

<?php
if(isset($_POST['message'])){
    $to      = 'queries@mydomain.com';
    $subject = $_POST['subject']; 
    $message = $_POST['message']; 
    $headers = "From: ".$_POST['sender_nam??e?']." <".$_POST['sender_em??ail??'].">\r\n"; $headers = "Reply-To: ".$_POST['sender_ema??il??']."\r\n"; 
    $headers = "Content-type: text/html; charset=iso-8859-1\r\n";
    'X-Mailer: PHP/' . phpversion();
    if(mail($to, $subject, $message, $headers)) echo json_encode(['success'=>true]); 
    else echo json_encode(['success'=>false]);
    exit;
 }
?>
