Is it possible to only get some properties from a form on submit?

<html><body>
<FORM name="foo" id="foo" onSubmit="dosubmit();return false;">
    <INPUT type="text" name="s" id="s"><BR/>
    <INPUT type="text" name="s2" id="s2"><BR/>

    <select name="si" id="si">
    <option>SomeOption_1</option>
    <option>SomeOption_2</option>
    <option>SomeOption_3</option>
    </select><BR/>
<input type="submit" value="submit" id="postDataSubmit">
</FORM>

<script>
function dosubmit() 
{
    //Extract value of S2 and the chosen option (si) from the form here, and nothing else. Show them in an alert.
}
</script>

</body></html>

    function dosubmit()
{
    alert(document.getElementById('s2').value);
    alert(document.getElementById('si').options[document.getElementById('si').selectedIndex].value);
}

    And by the way, if this is all you’re trying to do, then you don’t need a form. You can do this with any regular button:

    <button onclick="dosubmit()">Show values</button>
