Multiple keypress actions in JavaScript

Issue

I have this animated character that changes every time when I press navigation keys.

This character can jump, but if i try with spaceBar+rightKey. Nothing happens as I expected.

Character jumps normally and don't take right jump.

I want-

I tried to add a box in window, so that this character shouldn't go across this box, they can only jump/walk over it. I want to bind keys for making a directional jump.

Code-

if(spaceBar)
    {
        box.stop(true,false).animate({top:xPos-50},10, function(){
            box.animate({top:xPos},100);
        })

I tried

if(spaceBar,rightKey)
    {
        box.stop(true,false).animate({top:xPos-50},10, function(){
            box.animate({top:xPos},100);
        })

But that didn't do trick.
