$('button').click(function(){
    $(this).parent().before('<div class="comment_box_all"><div class="comment_user"></div></div>')
    var content = document.createElement("span");
   content.innerHTML=$(".textarea").val().replace(/(\n|\r|\r\n)/g, '<br>');
    $('.comment_user').append(content);
});
$(document).on("click", "button", function() {
	$(this).closest('.comment_panel').find('.textarea').val('')
});
 $('button').attr('disabled',true);
   $('.textarea').keyup(function(){
      if($(this).val().length !=0)
          $('button').attr('disabled', false);            
       else
          $('button').attr('disabled',true);
 });
.comment_panel
{
  width:450px;
  height:100px;
}
textarea
{
  width:300px;
  height:80px;
  }
button
{
  
  top:10px;
  left:330px;
 }
.comment_box_all
{
  width:450px;
  height:100px;
  background-color:#999;
  border:1px solid #000;
  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="comment_panel">
    <textarea class="textarea" placeholder="Add text..."></textarea>
    <button>Add comment</button>  
</div>

Could you help me how I can clear textarea after click button not using .val(''), because look, I would like disabled button when textarea is empty but this happen only in first add text, if I add text next time in textarea is '' and button is active

You can just add the disabled class every time the add button is clicked as you were doing for the first time .

$(this).attr('disabled',true);

Add this line inside the button onclick function.

$('button').click(function(){
    $(this).parent().before('<div class="comment_box_all"><div class="comment_user"></div></div>')
    var content = document.createElement("span");
   content.innerHTML=$(".textarea").val().replace(/(\n|\r|\r\n)/g, '<br>');
    $('.comment_user').append(content);
});
$(document).on("click", "button", function() {
	$(this).closest('.comment_panel').find('.textarea').val('')
    $(this).attr('disabled',true);
});
 $('button').attr('disabled',true);
   $('.textarea').keyup(function(){
      if($(this).val().trim().length !=0)
          $('button').attr('disabled', false);            
       else
          $('button').attr('disabled',true);
 });
.comment_panel
{
  width:450px;
  height:100px;
}
textarea
{
  width:300px;
  height:80px;
  }
button
{
  
  top:10px;
  left:330px;
 }
.comment_box_all
{
  width:450px;
  height:100px;
  background-color:#999;
  border:1px solid #000;
  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="comment_panel">
    <textarea class="textarea" placeholder="Add text..."></textarea>
    <button>Add comment</button>  
</div>
