Extending JavaScript Element "class"

[bluehtrombone]

Hi everybody,

I am trying to extend the JavaScript's native class Element as below. If I then create two or more distinct objects, assigning values to any of them affects all the objets as if they were referencing one and the same object. However, div1 == div2 throws false. Could anybody explain why is that and how to fix this issue?

function Div()
{
  //Empty
}

Div.prototype = document.createElement("DIV");

var div1 = new Div();
var div2 = new Div();

div1.style.border = "solid 1px black";
div2.style.border = "dashed 4px red";

document.body.appendChild(div1);

Thanks!

objects are passed by ref, not by value, and because div1 and div2 are different objects, they are not equivalent to javascript.

consider the simplest test case:

 var a={a:1}
 var b={a:1}
 alert(a==b)

it shows false, because objects don't compare like primitives.
