You can try this:

$(window).resize(function() {
    var height = $(window).height();
    var width = $(window).width();

    if (width > height) {
        // Landscape
        $("#mode").text("LANDSCAPE");
    } else {
        // Portrait
        $("#mode").text("PORTRAIT");
    }

});

Another one id window.orientation which return 0, 90 or -90 where:

• 0 stands for: portrait mode

• 90 stands for: landscape mode with the screen turned to the left

• -90 stands for: landscape mode with the screen turned to the right

   window.onorientationchange = function() 
  {
  var orientation = window.orientation;
  switch(orientation) {
      case 0:
          //Top side up.
          break; 
  
      case -90:
          //Left side up (turned 90 degrees to the right)
          break;
  
      case 90: 
          //Right side up (turned 90 degrees to the left)
          break;
    }
  }
