I have a Javascript object, eg:
var pessoa = {nome: 'Carlos', cpf: '123', rg: '456'};
I need to list the fields that this Object has and the corresponding values.
To list the fields I have achieved the following:
Object.keys(pessoa);
//Saída no Console..
nome
cpf
rg
Now I need a way to list only field values.
//a saída deve ser assim..
Carlos
123
456
would be something like Object.values (person), but it does not have this method ...
How can I do this?
You have to use a loop, if you need this in an array you can do this:
Object.keys(pessoa).map(function(prop){ return pessoa[prop];});
// que dá ["Carlos", "123", "456"]
You can also use for in , but it will be like Object.keys, a key iterator:
for (var prop in pessoa){
console.log(prop, pessoa[prop]);
}
// que dá :
// nome Carlos
// cpf 123
// rg 456
Interestingly in the MooTools library we have this method. The implementation is like this :
values: function(object){
var values = [];
var keys = Object.keys(object);
for (var i = 0; i < keys.length; i++){
var k = keys[i];
values.push(object[k]);
}
return values;
},
You can use a loop and put everything in another array:
var data = [{"nome":"Eduardo","cpf":"00.666.999-33"},
{"nome":"Paulo","cpf":"222.222.666-33"}];
var nomes = [];
for(i = 0; i< data.length; i++){
if(nomes.indexOf(data[i].nome) === -1){
nomes.push(data[i].nome);
}
}
for(i = 0; i< nomes.length; i++){
alert(nomes[i]);
}
