How to make two input feedback on Jquery ?
So far it turns out only from #element1 to #element2 :

  $('#element1').keyup(function() { var data = $('#element1').val(); $('#element2').val(data); }); 
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="element1"> <input type="text" id="element2">

     $('#element1').keyup(function() { var data = $('#element1').val(); $('#element2').val(data); }); $('#element2').keyup(function() { var data = $('#element2').val(); $('#element1').val(data); }); 
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="element1"> <input type="text" id="element2">
