    The code to set fullscreen is something like this:

    <script type="text/javascript">
        function requestFullScreen(element) {
            // Supports most browsers and their versions.
            var requestMethod = element.requestFullScreen || 
               element.webkitRequestFullScreen || 
               element.mozRequestFullScreen || 
            if (requestMethod) { // Native full screen.
            } else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
                var wscript = new ActiveXObject("WScript.Shell");
                if (wscript !== null) {
        var elem = document.body; // Make the body go full screen.

    But I don't think it's possible to trigger it when the page loads, beacuse it needs to be attached to an event handler on a page element (a button click, for instance).

    // Note the "moz" prefix, which is short for Mozilla.
    } else if (element.webkitRequestFullScreen) {
    // This is how to go into fullscreen mode in Chrome and Safari
    // Both of those browsers are based on the Webkit project, hence the same prefix.
    // Hooray, now we're in fullscreen mode!

    // var element = document.body; // Make the body go full screen.
    // requestFullScreen(element);

    If this is for something like a kiosk mode you generally have a command line switch allowing to enable this. Else the user should be left in control of deciding wether or not he wants to show your site in full screen mode. Anyway I believe this is a safety measure and that you have no way around this (precisely to let the user to control this especially for safety reasons, else a bad guy could fake whatever he wants and fool some users, for example showing a lock screen and let the user to post his password or whatever).
