Fibonacci Sequence is the series of numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, . . . Each subsequent number is the sum of the previous two.

<html>

<body>



 <input type text=text id=txtloop />

        <input type=button id=btnEnter value=Enter onclick=fibonacci_series(txtloop.value) />



        <p id=output></p>

<p id=demo></p>



<script>

var fibonacci_series = function (n) 

{

  if (n==1) 

  {

var loop = [0, 1];

   document.getElementById(output).innerHTML = loop;

  return loop;

  } 

  else 

  {

    var s = fibonacci_series(n - 1);

    s.push(s[s.length - 1] + s[s.length - 2]);

    document.getElementById(output).innerHTML =s;

    return s;

  }

   

};



</script>



</body>
