Is It Possible To Prevent Users Page Up, Page Down, Up And Down Arrow Keys From Scroll Functioning?

Using in html body overflow: hidden I managed to control the scroll flow of a webpage. Is it possible to also prevent users Page Up, Page Down, Up and Down arrow keys from scroll

Solution 1:

This was my solution:

var ar = newArray(33, 34, 38, 40);

$(document).keydown(function (e) {
    var key = e.which;
    if ($.inArray(key, ar) > -1) {
        e.preventDefault();
        returnfalse;
    }
    returntrue;
});

Solution 2:

Use preventDefault():

window.onkeydown=function(e){
   if(e.keycode==33 || e.keycode==34 || e.keycode==38 || e.keycode==40){
       e.preventDefault();
   }
}

Solution 3:

37 - left 38 - up 39 - right 40 - down

$(document).keydown(function(e){
   if(e.which>=36 && e.which<40){
       e.preventDefault();
   }
});
