如何强制Firebug按声明的顺序打印JSON属性？

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?

Answer 1

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]);
}
