Ajax http ошибка 200 - Не ошибается лишь тот, кто ничего не делает!

I have implemented an Ajax request on my website, and I am calling the endpoint from a webpage. It always returns 200 OK, but jQuery executes the error event.
I tried a lot of things, but I could not figure out the problem. I am adding my code below:

jQuery Code

var row = "1";
var json = "{'TwitterId':'" + row + "'}";
$.ajax({
    type: 'POST',
    url: 'Jqueryoperation.aspx?Operation=DeleteRow',
    contentType: 'application/json; charset=utf-8',
    data: json,
    dataType: 'json',
    cache: false,
    success: AjaxSucceeded,
    error: AjaxFailed
});
function AjaxSucceeded(result) {
    alert("hello");
    alert(result.d);
}
function AjaxFailed(result) {
    alert("hello1");
    alert(result.status + ' ' + result.statusText);
}

C# code for `JqueryOpeartion.aspx`

protected void Page_Load(object sender, EventArgs e) {
    test();
}
private void test() {
    Response.Write("<script language='javascript'>alert('Record Deleted');</script>");
}

I need the ("Record deleted") string after successful deletion. I am able to delete the content, but I am not getting this message. Is this correct or am I doing anything wrong? What is the correct way to solve this issue?

Добрый день. Помогите разобраться.
Есть форма

<form  id="feedback">
  <div class="form-group">
    <label>Name</label>
    <input type="text" class="form-control" id="name">
  </div>
  <div class="form-group">
    <label>email</label>
    <input type="email" class="form-control" id="email" >
  </div>
  <div class="form-group">
    <label>theme</label>
    <input type="text" class="form-control" id="theme" >
  </div>
  <div class="form-check">
    <label>
      massage
    </label>
    <textarea id="message" class="form-control"></textarea>
  </div>

  <button type="submit" class="btn btn-primary">Submit</button>
</form>

есть ajax запрос

$(document).ready(function(){
		
		$('button').on('click', function(e){
			e.preventDefault();
			
				sendMessage();
	
		});

		function sendMessage()
		{
			var user_name = $('#name').val(),
				user_email = $('#email').val(),
				user_theme = $('#theme').val(),
				user_message = $('#message').val();
			$.ajax({
				url: 'action.php',
				type: 'POST',
				dataType: 'JSON',
				data: {
					name: user_name,
					email: user_email,
					theme: user_theme,
					message: user_message
				},
				success: function(data){
						alert('done');
				},
				error: function(request, status, error){
					var statusCode = request.status; // вот он код ответа
					console.log(statusCode);
				}
			})
		}
	})

и есть файл action.php который обрабатывает ajax и должен записывать в базу

$name = $_POST['name'];
$email = $_POST['email'];
$theme = $_POST['theme'];
$message = $_POST['message'];

$db_host = "*****"; 
$db_user = "*****"; 
$db_password = "******"; 
$db_table = "feedback";     


$db = mysql_connect($db_host,$db_user,$db_password) OR DIE("Не могу создать соединение ");
// Выборка базы
mysql_select_db("*****_db",$db);
 
mysql_query ("INSERT INTO feedback (name, email, theme, message,) VALUES ('$name', '$email', '$theme', '$message')");

во время выполнения ajax отрабатывает error: и в консоль выводит статус 200 и в базу ничего не записывается

Hi, I'm doing a simple ajax example but for some reason it keeps fireing 'error' yet the status returned is 200. Any reasons 'success' is not fired with the simple message? Do I need to reference the json library or is this included with jquery?  

Default.aspx :
<script type="text/javascript" src="scripts/jquery-1.4.3.min.js"></script>  
<script type="text/javascript">      
      function getMessage()
      {            
        $.ajax({
              type: "POST",              
              url: "Default.aspx/sayHello",
              contentType: "application/json; charset=utf-8",
              data: "{}",              
              dataType: "json",
              success: function(response)              
              {
                alert(response.d);
              },
              error: function(response)              
              {
                alert(response.status);
              }
          }); 
      }                    
  </script>  
<title>Calling a page method with jQuery</title>

<body>    
    <form id="form1" runat="server">                      
        <input type="button" value="get message" onclick="getMessage()" />

It was probably an issue with caching that was cleared up with the reboot. Depending on your browser settings, the ajax url could have been cached and returned an old error even though the code had been changed. I have had this happen in the past. One
hacky method around this is to append an unused querystring parameter that will be different for each request. To do this I will add the current date/time as a querystring parameter. This will force the browser and the server to pull up a new
version of the page regardless of the caching settings.

I am receiving the following Ajax error when on any Views page. The Drupal logs (/admin/reports/dblog) don’t have any corresponding events. I’ve tried disabling all custom and view related modules and adjusting jQuery versions with no success.

I’m running Drupal 7.57-dev and Views 7.x-3.18

I know there are several other questions about this error but their solutions are specific or not relevant to this specific response text.

How do I begin drupal shooting this error?

The <?php tag at the beginning of the ResponseText indicates that there is a stray <?php in the markup, this was being caused by a syntax error in a completely unrelated template.
After template syntax error was fixed the Ajax Http 200 error pop-up went away.
