How to get object name?

Is it possible to output the name of an object in javascript? In the below script i pass the window object to a function and output the attributes.

var Output = "";

function OutputAttributes(pObject)
{
    var x = "";

    for (var Attribute in pObject)
    {
        x = x + "<li>"+pObject+"." + Attribute + ": " + pObject[Attribute] + "</li>";
    }
    return x;
}

Output = OutputAttributes(window);

document.write("<h2>Attributes from Objekt <i> <\/i><\/h2>");
document.write("<ol>"+Output+"</ol>");

If i execute my above code, then i receive output like this:

[object Window].close: function close() { [native code] } 
[object Window].stop: function stop() { [native code] } 
[object Window].focus:function focus() { [native code] }

But i expected something like this:

window.focus:function focus() { [native code] }

<script>
var str ="[object Window].focus:function focus() { [native code] }";
str = str.replace("[object","");
strlast=str.replace("Window]","Window");

alert(strlast);
</script>

It's not possible in JavaScript, because arguments in this language are passed by value or by reference, not by name, so when variable is passed to function, its name is lost.
