## jQuery Mobile orientationchange Event

The orientationchange event is triggered when the user rotates the mobile device vertically or horizontally.

To use the orientationchange event, attach it to the window object:

$(window).on("orientationchange",function(){
alert("The orientation has changed!");
});

The callback function can have one argument, the event object, which returns the orientation of the mobile device: "portrait" (the device is held in a vertical position) or "landscape" (the device is held in a horizontal position):

## Example

$(window).on("orientationchange",function(event){
alert("Orientation is: " + event.orientation);
});
Try it yourself »

Because the orientationchange event is bound to the window object, we can use the window.orientation property to, for example, set different styles to distinguish between portrait and landscape views:

## Example

$(window).on("orientationchange",function(){
if(window.orientation == 0) // Portrait
{
$("p").css({"background-color":"yellow","font-size":"300%"});
}
else // Landscape
{
$("p").css({"background-color":"pink","font-size":"200%"});
}
});
Try it yourself »

| The window.orientation property returns 0 for portrait and 90 or -90 for landscape view.
