JavaScript: Parent -> Frame function calls

For this example I have 2 html pages:

Page1.html and Page2.html

If Page2 is shown as iframe inside Page1 and has this function:

<script type="text/javascript">
        function showMessage(m) {
            document.getElementById("message").innerHTML = m;

Than it can be called from Page1 like this:

<script type="text/javascript">
    window.onload = function() {
        window.frames[0].showMessage("Hello from Main Page in iFrame");
