iPad doesn't trigger resize event going from vertical to horizontal?

Question

Has anyone noticed this behavior? I\'m trying to write a script that will trigger upon a resize. It works fine on normal browsers, works fine on iPhone, but on iPad, will on

Answer 1

If I understood you correctly, you want to do something when the user tilts the iPad. Here you go:

window.onorientationchange = function(){

    var orientation = window.orientation;

    // Look at the value of window.orientation:

    if (orientation === 0){

        // iPad is in Portrait mode.

    }

    else if (orientation === 90){

        // iPad is in Landscape mode. The screen is turned to the left.

    }


    else if (orientation === -90){

        // iPad is in Landscape mode. The screen is turned to the right.

    }

}

Check your version of iOS.

The "orientationchange" event does not work in iOS 3.*, but it does in 4.*

Answer 4

1. do a nice check if your platform is iPad,

2. handle the iOS specific event orientationchange by catching window.onorientationchange

   if(navigator.platform == 'iPad') {
       window.onorientationchange = function() {
           // handle orientationchange event
           // (here you can take advantage of the orientation property
           //     - see the good answer above by Vincent)
       }       
   }
   

Answer 5

I think what you want would be to use the iPad Orientation CSS, which looks like this:

<link rel="stylesheet" media="all and (orientation:portrait)" href="portrait.css" />
<link rel="stylesheet" media="all and (orientation:landscape)" href="landscape.css" />

Also, the orientationchange event fires when the orientation is changed, according to iPad web development tips.

Together, that should give you tools enough to deal with the change.

Answer 6

The only thing I could find from apple:

Safari on iPad and Safari on iPhone do not have resizable windows. In Safari on iPhone and iPad, the window size is set to the size of the screen (minus Safari user interface controls), and cannot be changed by the user. To move around a webpage, the user changes the zoom level and position of the viewport as they double tap or pinch to zoom in or out, or by touching and dragging to pan the page. As a user changes the zoom level and position of the viewport they are doing so within a viewable content area of fixed size (that is, the window). This means that webpage elements that have their position "fixed" to the viewport can end up outside the viewable content area, offscreen.

I understand the "works on the iPhone" part...but maybe it doesn't anymore? This could be a change in OS/mobile Safari since the latest public iPhone OS release shipped (the above documentation is from March 2010).

I'm going to re-tag this question adding iPhone to it, maybe one of the guys with the developer 4.0 OS release can test this? If it is the case it's been removed, this should be a bug filed/fixed before it goes live...I'm not sure on how the procedures are on this with Apple are though.
