Assume an object as follows:
vendas = {
obs1:{
Venda1:{Regiao:"Norte", Valor: 200},
Venda2:{Regiao:"Sul", Valor:100}
},
obs2:{
Venda1:{Regiao:"Norte", Valor: 50},
Venda2:{Regiao:"Sul", Valor:20}
}
}
What are the ways of knowing the "size" of the object, that is, how many "other objects" are inside it?
One solution I found was to use the Object.keys() function together with length :
Object.keys(vendas).length //2, isto é Obs1 e Obs2
Object.keys(vendas.obs1).length //2, isto é, Venda1 e Venda2
In older browsers you may need to loop through the object:
var tamanho= 0;
for (var i in vendas) {
if (vendas.hasOwnProperty(i)) {
tamanho++;
}
}
