.submit() does not act as pressing the submit button – Blancer.com Tutorials and projects

I have a form.
When I exit the text field it should alert “HH” and submit the form – run a PHP script.
if I exit the text field, I get the alert but it is not submitted.
only pressing the submit button calls the PHP script.
what I’m doing wrong?
I found a few questions as my, tried the solution, but it not working.

    <html>
      <head>
       <script src="vendor/jquery/jquery-3.2.1.min.js"></script>
       <script>
          $(document).ready(function(){
          $("#faults_form input").blur(function(){
            alert("HH");
            $("#faults_form").submit();
            return false;
          });
        });

   </script>
    
  </head>



<body>
    <form id="faults_form" name="faults_form" action="/index.php" method="post" enctype="multipart/form-data">
    
    <label for="name">Enter server name:</label>
    
    <input type="text" name="name" value="" >
    <input type="submit" name="submit" value="Submit">
    </form>
 </body>
</html>
