Utilize JavaScript to identify the orientation of an iPad device

I have implemented the code below to monitor the orientation of the iPad. However, it seems that this method is only triggered when I physically rotate the device or change its orientation. If the app is launched in landscape mode and I navigate to a different screen, the method does not execute. Is there a way to detect the iPad orientation without actually rotating the device?

$(window).bind('orientationchange', function (event) {
    if (event.orientation == "landscape") {
        set frame for landscape
    } else {
        set frame for portrait
    }
});

Answer №1

Here is another way you could make it function:

$(window).on('orientationchange', function(event) {
  alert('orientation has changed to:' + event.orientation);
});

Answer №2

$(window).on('load orientationchange', function(event) {
    if(event.orientation == "landscape")
    {
        apply styles for landscape orientation
    }
    else
    {
        apply styles for portrait orientation
    }
});

It is advisable to add the load event as well. This ensures that the specific window content is available in the DOM when the window.load event is triggered. If the content is dynamically inserted into the DOM (as recommended by @Tushar), you can trigger the event after the insertion.

Remember that orientation change or resize events may not be triggered when the page initially loads. To ensure they run initially, include the load event as well, or trigger them later if they depend on dynamic DOM elements.

Answer №3

This script first verifies the presence of an iPad device and then proceeds to compare its height with its width. 

var isiPad = navigator.userAgent.indexOf('iPad') != -1

//or
var ua = navigator.userAgent;
var isiPad = /iPad/i.test(ua)
if (isiPad) {
$(window).on('load orientationchange', function(event) {
    if(window.innerHeight > window.innerWidth){
        console.log("Device is in portrait mode.");
    } else {
        console.log("Device is in landscape mode.");
    }
});
}
