Answer 1

Your function is correct, but js Element class have no show() and hide() methods. You can implement it using prototype. As an example

Element.prototype.hide(){
this.style.display = "hidden";
} 
Element.prototype.show(style){
style = style ? style : "block";
this.style.display = style;
}

But better use jquery or something like this.
