[jQuery] jQuery suggestion

I'm using IntelliJ Idea 9.0 which supports code completion/suggestion for
javascript. It doesn't work with the innerHeight/Width because of this

        // innerHeight and innerWidth
        jQuery.fn["inner" + name] = function(){
                return this[0] ?
                        jQuery.css( this[0], lower, false, "padding" ) :
                        null;
        };

Is there anyway to implement the innerHeight and innerWidth in a regular
way?
