Add iPhone/iPad Orientation to Body Class
This function will detect the orientation (portrait/landscape) of an iOS device and set the body class to either portrait or landscape, as well as providing a global variable for use elsewhere in your JS.
If you require multiple classes on your body tag, simply alter the code to use jQuery’s addClass() and removeClass() functions.
function orient() {
if (window.orientation == 0 || window.orientation == 180) {
$("body").attr("class", "portrait");
orientation = 'portrait';
return false;
}
else if (window.orientation == 90 || window.orientation == -90) {
$("body").attr("class", "landscape");
orientation = 'landscape';
return false;
}
}
/* Call orientation function on page load */
$(function(){
orient();
});
/* Call orientation function on orientation change */
$(window).bind( 'orientationchange', function(e){
orient();
});
