I'm trying to submit a form without a button by calling a JavaScript function and executing the form using JQUERY/PHP. I want the form to execute silently on the backend without reloading the page. Unfortunately, it keeps returning a JavaScript function undefined error, even though it's on the page. Admittedly, I'm not good at JavaScript, so please treat me like a noob and point me in the right direction. Thank you, my code is

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="my_1form" action="" method="POST">
    <input type="text" name="acc_name" id="acc_name" value="name"/>
    <br/>
    <input type="text" name="with_id" id="with_id" value="1"/>
     <div onclick="submit_1form()">Submit</div>

</form> 

<script>
$(document).ready(function() {
  function submit_1form() {
    var fo1rm = document.getElementById("my_1form");
    fo1rm.submit();
    var acc_name = $("#acc_name").val();
    var with_id = $("#with_id").val();

    var dataString = 'acc_name=' + acc_name +
      '&with_id=' + with_id; {
      // AJAX Code To Submit Form.
      $.ajax({
        type: "POST",
        url: "submit-withdraw.php",
        data: dataString,
        cache: false,
        success: function(result) {}
      });
    }
    return false;
  }
});
</script>

Please note that I am using the header tag <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js">< Jquery script is called in /script>< /p>

Thank you so much!
