我正在尝试创建一个喜爱的按钮，当点击将喜爱的消息而不重新加载。 所有的代码都是正确的，只是我很难弄清楚如何将每个消息的单独ID发送到ajax响应。

我的Ajax:

   $(document).on('submit', '.favourite-form', function(e) { 
   e.preventDefault();
   var data = $(this).serialize();  
   $.ajax({ 
  data: data, 
  type: "post", 
   url: "favorite.php?message=529", // here i put 529 as an example, 
  i need it to be a variable that changes based on which message has been clicked.
  success: function(data) { 
  alert("Data Save: " + data); 
    },
    error: function(jqXHR, textStatus, errorThrown) //gracefully handle any errors in the UI
    {
   alert("An ajax error occurred: " + textStatus + " : " + errorThrown);
  }
}); 
 }); 

我的HTML。

   <form class="favourite-form" method="post">

        <a class="msg-icon " href="<?php echo "reply?message=" . $row['msgid'] . ""; ?>"></a>
       <button type="submit" name="fav" value="<?php echo $row['msgid'] ?>" ></button>
        </form>

我的php依赖于通过$_GET方法发送的消息的id。

我的php:

        $user_id = $_SESSION['active_user_id'];


            extract($_GET);
            $id=$_GET['message'];

            $q=$db->prepare("SELECT msgid,date,text

            FROM messages 
            WHERE to_id=? and msgid=?");
            $q->bindValue(1,$user_id);
            $q->bindValue(2,$id);
            $q->execute();
            $row2=$q->fetch();
            $d=$row2['date'];


            $fav_questionq=$db->prepare("SELECT *
            FROM messages
            LEFT JOIN users
            ON messages.to_id=users.id
            WHERE users.id=? AND messages.msgid=?

            ");
            $fav_questionq->bindValue(1,$user_id);
            $fav_questionq->bindValue(2,$id);
            $fav_questionq->execute();
            $frow=$fav_questionq->fetch();

            $fquestion= $frow['text'];


            $result = $db->prepare("SELECT * FROM fav_messages
                                WHERE username=? AND message=?");
            $result->bindValue(1,$user_id); 
            $result->bindValue(2,$id);              
            $result->execute();


        if($result->rowCount()== 1 )
        {
            $deletequery=$db->prepare("DELETE FROM fav_messages WHERE message=?");
            $deletequery->bindValue(1,$id);
            $deletequery->execute();

        }
        else
        {
        $insertquery = $db->prepare("INSERT INTO fav_messages (username,message,fav_question,fav_date) values(?,?,?,?)");
        $insertquery->bindValue(1,$user_id);
        $insertquery->bindValue(2,$id);
        $insertquery->bindValue(3,$fquestion);
        $insertquery->bindValue(4,$d);
        $insertquery->execute();
        }



        ?>

如何通过ajax发送每个消息id，例如:favorite.php？message=“包含每个消息id的某个变量”
