Passing the values from dynamically created textboxes to an array using JavaScript only

I wanted to add textboxes dynamically and then pass the values written in these textboxes to
an array. here is my code.

    function add(type)
 {
    a=new Array();
    for(c=0;c<3;c++)
        {
           var element = document.createElement("input");
           element.setAttribute("type", type);
           element.setAttribute("value", type);
           element.setAttribute("name", type);
           element.setAttribute("id", 'n'+c);
           var foo = document.getElementById("fooBar");
           a[i]=document.getElementById('n'+c);
           foo.appendChild(element);

        }
  }
    </SCRIPT>
    </HEAD>
    <BODY>
    <FORM>

    <SELECT name="element">
    <OPTION value="button">Button</OPTION>
      </SELECT>
     <INPUT type="button" value="Add" onclick="add(document.forms[0].element.value)"/>

I imagine the problem is that the element isn't part of the document until you call foo.appendChild(element); so doing document.getElementById('n'+c); isn't returning anything. However, that's totally unnecessary anyway. If it were part of the document, document.getElementById('n'+c); is just going to return exactly what you already have referenced by element, so you should be able to just do:

a[c] = element;
