Can I trigger a CSS event in mobile safari upon iphone orientation change?

Question

I\'m trying to figure out how to change an embedded web page when the user rotates their phone from portrait to landscape mode - basically to load a view that is better suit

Answer 1

The Safari mobile browser has support for the orientationchange event as well as the orientation property on the window, so you can do something like:

window.onorientationchange = function() {
    switch(window.orientation) {
        case 0:   // Portrait
        case 180: // Upside-down Portrait
            // Javascript to setup Portrait view
            break;
        case -90: // Landscape: turned 90 degrees counter-clockwise
        case 90:  // Landscape: turned 90 degrees clockwise
            // Javascript to steup Landscape view
            break;
    }
}

I would add the upside-down because the iPad human interface guidelines say you should support all orientations, so I would expect Safari on the iPad (and possibly future iPhone versions) to support it.
