object name as string

Question

Is there any way in jQuery to get the name of an object as a string?

i.e. if I have

markers.events = {
    click: function(event){},
    drag: function(event){}
};

I would like to get a string "click" or "drag"

Is this possible inside a $.each(myObj, function(){})?

I need to do the following (hopefully) on the object stated above:

$.each(markers.events, function(i, event){
    google.maps.event.addListener(marker, "click/drag", event);
})

It is not the name of the object. It is the name of the variable. Several variables can have a reference to the same object. — Felix Kling, Mar 14 '11 at 19:38
Why don't you ask a question centered around what it is that you're trying to accomplish? — Pointy, Mar 14 '11 at 19:39
@justkt The question you are referring is not useful. The OP of that question decided to go with object literals instead, so that question is technically unanswered. — Šime Vidas, Mar 14 '11 at 20:02
@Sime - now that the question has been edited there is a significant difference, I agree. It was less obvious before. — justkt, Mar 14 '11 at 20:17
My aplogies, need to learn to slow down and explain more. ;o) — designermonkey, Mar 15 '11 at 15:23

You could use window["myObj"] , although it only works with Global variables.

The object itself does not have a name. If you do this:

var x = {};

then an object will be created and the variable x will have a reference to it. However, the name of the object is not 'x'. The object is nameless.

You can even declare another variable and set its reference to that same object:

var y = x;

Now both x and y contain a reference to the same (nameless) object.

What you want is stringify the name of a variable, based on its identifier name. That cannot be done.

Update:

The first argument of the $.each callback contains the name of the property:

$.each(markers.event, function(i, v) {
    google.maps.event.addListener(marker, i, v);
});

I've updated the question to be more relevant, can it be done from the new question? – designermonkey Mar 14 '11 at 20:03
Brilliant! I should have known really. I thought it was an integer iterator, but it's a key isn't it. Thanks v much! – designermonkey Mar 14 '11 at 21:45

You would do well to explain why you need this so we could help better, but you could do something like this:

var myVars = {
    "myVar1": "Yaay",
    "myVar2": "Yaay again"
};

for(var a in myVars){
    alert("Variable name: "+a);
}
