I’m trying to learn javascript. For an exercise I want to make a page with a list, text box and a button. Pressing the button would add the text to my list. My code:

<html>
<head charset="utf-8">
   <script type="text/javascript">
      var array = new Array()
      array.push("test")

      function pusher() {
         array.push( document.forms["former"]["finput"].value )
      }
   </script>
</head>
<body>
   <form name="former" onsubmit="pusher()">
      <input type="text" name="finput" />
      <input type="submit" value="Submit" />
   </form>

   <ul type="disc">
      <script type="text/javascript">
         for (var i = 0; i < array.length; i++)
            document.write("<li>"+array[i]+"</li>")
      </script>
   </ul>
</body>
</html>

If I add alert() to pusher(), I see that every time I click submit the elements are reset. So, how do I redraw my list without resetting the values of array?

    Apparently elements of a HTML can be altered using the method 

    document.getElementById("my_element_id").innerHTML = "new HTML code"

    (figured it’s no good to keep a question unanswered)
