Javascript - Filter array of objects

Navigation
1

And I have an array of objects in javascript: 

var array = 
[
    {
        conta_id : "7",
        marcar : 1,
        pag_data_emissao : "04/08/2015",
        pag_debito_credito : "D",
        pag_historico : "CHEQUE 331107  VENDA S",
        pag_id : "47782",
        pag_utilizado :"VENDA S",
        pag_valor : "7.000,00"
    },
    {
        conta_id : "7",
        marcar : 0,
        pag_data_emissao : "07/08/2015",
        pag_debito_credito : "D",
        pag_historico : "DEPOSITO 3117  VENDA X",
        pag_id : "47783",
        pag_utilizado :"VENDA X",
        pag_valor : "640,63"
    }
];

I would like to filter the array with the .filter () method where I would return all objects that have the attribute == 1, but I only found literature and English so I could not understand how it would look. 

var a = array.filter(function(obj){ obj.marcar==1; });

With the above code it does not give an error but it does not bring me anything either.

The only problem is that the function you use has to return the value. Change your code to: 

var filtrado = array.filter(function(obj) { return obj.marcar == 1; });

That will work.
