    This is considered more reliable and might work:

    <body>
    <iframe name=iframetest src="alt.html">
        <p>Your browser does not support iframes.</p>
    </iframe>
    <script>
        $(window).load(function(){
             window.frames['iframetest'].myFunction();
        });
    </script>
    <button onclick="myFunction();">Click Me</button>
</body>

    Here's a link that will explain it.

    also make sure alt and index.html are within the same domain using the same protocol (HTTP or HTTPS)
