Really silly zoom in Javascript

function ZOOM()
{
    if (document.body && document.body.style && typeof document.body.style.zoom != "undefined")
    {
        if (document.body.style.zoom=="400%")
            document.body.style.zoom = "100%";
        else
        {
            document.body.style.zoom = "400%";
            alert('You\'ve doubleclicked on the document.\nDoubleclick again to unzoom.');
        }
    }
}
document.ondblclick=ZOOM;

This will enlarge all resizeable items by 4x when you double-click on the document.
