    Hi i'm starting to learn javascript and i'm making a program that will ask the user for a number and then display all odd numbers which are less then or equal to whatever number the user chose. Here is what i have so far,

    
<!-- odd.html -->
<html>
  <head>
    <title>odd</title>
      <style type="text/css">
        body {
              background-color:#22DD44;
	      color:#DD22EE;
	      font-size:30;
       	      text-align:center;
	     }
      </style>
  </head>
  <body>
    <script type="text/javascript">
      var limit, count, stroutput;
      count = 1;
      stroutput = "";
      document.write("<h1>Odd</h1>");
      limit = prompt("Enter the limit", "");
      if (limit == null)
      {
       stroutput = ("You clicked cancel. No count will be shown.");
      }
      else if (limit == "")
      {
       stroutput = ("Limit must be entered.");
      }
      else if (limit != parseInt(limit))
      {
       stroutput = ("Limit must be a valid whole number");
      }
      else
      {
      while (count <= limit) {
	stroutput = stroutput + count + "\n";
	count = count + 1;
      }
      }
      alert (stroutput);
      document.write("<br /><br />");
      document.write("<br /><br />");
      document.write("<input type='button' name='cmdReload'");
      document.write(" value='Do again' onclick='window.location.reload()' />");
    </script>

  </body>
</html>
    Code (markup):
    As you can see so far it just shows you all numbers but i need it to only show odd numbers. How would i do this?


    EDIT Nevermind i got it going.

    Here is the code that you want

    
<!-- odd.html -->
<html>
  <head>
    <title>odd</title>
      <style type="text/css">
        body {
              background-color:#22DD44;
	      color:#DD22EE;
	      font-size:30;
       	      text-align:center;
	     }
      </style>
  </head>
  <body>
    <script type="text/javascript">
      var limit, count, stroutput;
      count = 1;
      stroutput = "";
      document.write("<h1>Odd</h1>");
      limit = prompt("Enter the limit", "");
      if (limit == null)
      {
       stroutput = ("You clicked cancel. No count will be shown.");
      }
      else if (limit == "")
      {
       stroutput = ("Limit must be entered.");
      }
      else if (limit != parseInt(limit))
      {
       stroutput = ("Limit must be a valid whole number");
      }
      else
      {
      while (count <= limit) {
        if(count%2==1){
            stroutput = stroutput + count + "\n";
        }
	    count = count + 1;
      }
      }
      alert (stroutput);
      document.write("<br /><br />");
      document.write("<br /><br />");
      document.write("<input type='button' name='cmdReload'");
      document.write(" value='Do again' onclick='window.location.reload()' />");
