How can I force Firebug to print my JSON properties in the order they are declared?

Question

I'm building JSON with JavaScript. Here's my object:

catalogoJSON = {
    condicion: condicionCatalogos0,
    tipo: tipoCatalogos0,
    idCatalogo: idCatalogo0,
    valor: valorCatalogos0
};

But when I print it with Firebug, I get my properties printed alphabetically like this:

{
    condicion: condicionCatalogos0,
    idCatalogo: idCatalogo0,
    tipo: tipoCatalogos0,
    valor: valorCatalogos0
}

Is there a way in JavaScript to get back my JSON with its properties in the order that I declare them, without having to change my properties' names?

Why would you want them in order? Object properties' order is not guaranteed anyways therefore it should not matter. — Joseph, Jul 24 '12 at 17:48

for the application i´m developing it´s important that i get them in the order i declare them. — linker85, Jul 24 '12 at 17:52

Objects in JavaScript have no inherit order. Firebug just prints then alphabetically, because it feels like it (Chrome's dev tools to that too).

You can try to loop through the object, and print it yourself, that may keep the order.

for(var x in catalogoJSON){
    console.log(x, catalogoJSON[x]);
}

As far as I know, browsers do keep them in order during a loop but standards suggest that they shouldn't be. So... I'd not rely on it. – Joseph Jul 24 '12 at 17:53
