Can I limit the number of rows a user can type into a TEXTAREA (IE5.5 only)??

M. Expósito, Patrick Mullin,

some code...:
Only limit the number of new lines

<SCRIPT> 

function checkMaxRow (textarea, maxrow) 
{
var cantidad = textarea.value.match(/\n+/g);
var cuenta = cantidad?cantidad.length:0;
   	if (cuenta < maxrow) 
    	{ return true;}
  	else
	{
	textarea.selected = false;
	return false;}
}


</SCRIPT>

And the call to function:

<textarea name="observaciones" cols="120" rows="15" wrap="HARD" 
          ONKEYDOWN="return checkMaxRow(this, 14)">
