The code below is intended to enable the submit button once the user clicks in the textarea field. It works, but I'm trying to also make it so that it's only enabled if there's at least one character in the field. I tried wrapping it in:

if($(this).val().length > 1) 
{

}

But, that didn't seem to work... Any ideas?

    $("#fbss").focus(function(){
            $(this).select();
                if($(this).val()=="Default text") {
                $(this).val("");
                $("input[id=fbss-submit]").removeClass();
                $("input[id=fbss-submit]").attr('disabled',false);
                $("input[id= fbss-submit]").attr('class','.enableSubmit');
                if($('.charsRemaining')) {
                    $('.charsRemaining').remove();
                    $("textarea[id=fbss]").maxlength({
                        maxCharacters: 190,
                            status: true,
                            statusClass: 'charsRemaining',
                            statusText: 'characters left',
                            notificationClass: 'notification',
                            showAlert: false,
                            alertText: 'You have exceeded the maximum amount of characters',
                            slider: false
                    });

                }
        });
