}
function execmascara(){
  v_obj.value=v_fun(v_obj.value)
}
function mreais(v){
  v=v.replace(/\D/g,"")           //Remove tudo o que não é dígito
  v=v.replace(/(\d{2})$/,",$1")       //Coloca a virgula
  v=v.replace(/(\d+)(\d{3},\d{2})$/g,"$1.$2")   //Coloca o primeiro ponto
  return v

        return (parseFloat(el.value.replace(/\./g, "").replace(",", "."), 10) || 0) + soma;
    }, 0);
    document.getElementById('result').value = soma;


}

<input type="text" class="form-control" name="total" id="result" readonly>

Answer 1

Apply the mask function after inputar the result in it.

document.getElementById('result').value = soma;

// Aplica Máscara
mascara(document.getElementById('result'), mreais);
