        $data = $this->accounts_model->get_count($id);
        echo json_encode($data);
    }

and the modle function

    public function get_count($id){
        $sql="SELECT COUNT(*) FROM $this->tablename";

<script>
    $('#sub_account').change(function(){

      var subaccount = document.getElementById("sub_account").value;
      //-------- loop to get count of sub accounts and add sum  1 ------------
      $.ajax({
            type: 'GET',
            url: "<?php echo base_url();?>index.php/accounts/get_subaccount_count/" $('#main_code').val(),
            data: {},
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
              $('#account_code').empty();
              $.each(result.result, function(){ 
                $('#account_code').value = this[0];
                })}
            
        });
      //-------- loop to get count of sub accounts and add sum  1 ------------
      });
      
           
</script>
 

i want the $('#account_code').value = is the count result

Your controller only needs to call the model method and print the returned integer.

public function get_subaccount_count(int $id): void
{ 
    echo $this->accounts_model->get_count($id);
}

Your model doesn't benefit from the $sql declaration.

public function get_count(int $id): int
{
    return $this->db->where('node_parent',$id)->count_all_results($this->tablename);  
}

Your ajax block only needs to assign the printed value to the desired HTML element.

$.ajax({
    type: 'GET',
    url: "<?php echo base_url();?>index.php/accounts/get_subaccount_count/"   $('#main_code').val(),
    success: function (response) {
        $('#account_code').value = result;
    }
});

Or use $.get like this:

$.get("<?php echo base_url();?>index.php/accounts/get_subaccount_count/"   $('#main_code').val(), function(result) {
    $('#account_code').value = result;
});

Change like this:

$.ajax({
            type: 'GET',
            url: "<?php echo base_url();?>index.php/accounts/get_subaccount_count/" $('#main_code').val(),
            data: {},
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (result) {
              $('#account_code').empty();
              var counter = 0; // this line
              $.each(result.result, function(){ 
                counter  ; //this line
                })}
              $('#account_code').value = counter; // and this line
            
        });
