Nice:

    */

    var countdown = {
        init: function() {
            countdown.remaining = countdown.max - $(countdown.obj).val().length;
            if (countdown.remaining > countdown.max) {
                $(countdown.obj).val($(countdown.obj).val().substring(0,countdown.max));
            }
            $(countdown.obj).siblings(".remaining").html(countdown.remaining + " characters remaining.");
        },
        max: null,
        remaining: null,
        obj: null
    };

.bc

I make my own :) like this :

<?php  

protected function txtMotif_Create() {    
      $this->txtMotif = new QTextBox($this);
      $this->txtMotif->TextMode = QTextMode::MultiLine;
      $this->txtMotif->Name = QApplication::Translate('Motif de suppression');
      $this->txtMotif->Text = $this->objSuppression->Motif;
      $this->txtMotif->Required = true;
      $this->txtMotif->Rows = 10;
      $this->txtMotif->Columns = 70;
      $this->txtMotif->CssClass = 'element_right';
      $this->txtMotif->MaxLength = $this->motifMaxLength;
      $this->txtMotif->AddAction(new QKeyUpEvent(), new QAjaxAction('Count_char'));
}

protected function Count_char($strFormId, $strControlId, $strParameter) {
                    
    $restant = $this->txtMotif->MaxLength - strlen($this->txtMotif->                
    $this->lblCount->Text = $restant."/".$this->txtMotif->MaxLength;
}

?>
