If someone tells you that you have to analyze it with functions on the string, it would be a serious mistake. The correct way to do it is to take the sctring to DOM. In jQuery, we use $. ParseHTML () :

var data = "<option codigo='1'></option>,<option codigo='2'></option>";

var html = $.parseHTML(data);

var resultado = $(html).map(function() {
  return $(this).attr('codigo');
})
.get()
.join(',');

console.log('Resultado:', resultado);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

$.parseHTML() returns an array of nodes, about which we use .map() to filter the information we want: in this case .attr('codigo') .
