Contar dígitos num textbox de múltiplas linhas ignorando espaços

Question

Olá pessoal,

Fiz o código abaixo para contar os caracteres digitados num textbox de múltiplas linhas mas ele conta os espaços. Preciso que, na contagem, ignore os espaços tanto antes e depois como entre as palavras.

<script language="javascript" type="text/javascript">

        function countChars(countfrom, displayto) {
            
            var len = document.getElementById(countfrom).value.replace(/^\s+|\s+$/g,'').length;
            document.getElementById(displayto).innerHTML = "Nº de Dígitos: " + len;
            
            if (len == 0)
            {
                document.getElementById(displayto).innerHTML = "";
                document.getElementById('divContar').className = 'contar1';
            } else
                if (len > 0 && len < 1000)
                {
                    document.getElementById('divContar').className = 'contar1';
                } else 
             
                if (len > 0 && len <= 1000)
                {
                    document.getElementById('divContar').className = 'contar2';
                } else 
                    if(len > 1000 && len <=1500)
                    {
                        document.getElementById('divContar').className = 'contar2';
                    } else
                        if(len > 1500)
                        {
                            document.getElementById('divContar').className = 'contar3';
                        };
        }
    </script>

 

Já alterei a linha 

var len = document.getElementById(countfrom).value.replace(/^\s+|\s+$/g,'').length;

para

var len = document.getElementById(countfrom).value.trim().length;
var len = document.getElementById(countfrom).value.replace(/^\s+|\s+$/g,'').trim().length;

 

E não funcionou.

Alguém pode me ajudar?

Grato,

 

ilano.
