How to restrict the user not to enter characters in the summernote textarea?

I'm using summernote editor and what I want to do is to restrict the user from adding characters if the text area is pre filled, but I couldn't figure out how to restrict the user not to enter a single character in the text area. Here is my code

 $(document).ready(function() {
  $('#summernote').summernote({
   callbacks: {
     onKeydown: function(e) {
      if(e.keyCode > 64 && e.KeyCode < 122)
      {
         e.target.blur();
      }
    }
  }
 });
});

<div class="container mt-3">
 <div class="inner-container">
    <div id="summernote1">
          Hello Summernote ! please enter text.
     </div>
  </div>

</div>

<script type="text/javascript">
$(document).ready(function() {
  $('#summernote1').summernote({
   callbacks: {
     onKeydown: function(e) {
      if(e.keyCode > 0)
      {
         e.preventDefault();
      }
    }
  }
 });
});

</script>
</body>
</html>

    I simply added this code in my html page and it worked for me.

    $(document).ready(function() {
  $('#summernote1').summernote({
   callbacks: {
     onKeydown: function(e) {
      if(e.keyCode > 0)
      {
         e.preventDefault();
      }
    }
  }
 });
});
