Module pattern context issue

Question

How to access private variable "state" in the delete confirmation function. The "this" keyword points me to the window object.

var usersController = (function() {
  var state = {},

    init = function(defaultState) {
      state = defaultState;

      $(".btn-delete-row").on("click", function() {
        var recordId = $(this).attr("data-record-id");
        showDeleteConfirmation(recordId);
      });
    },

    showDeleteConfirmation = function(recordId) {
      //how to access state private variable here???
    };

  return {
    init: init
  };
}());

and I call it like this:

$(function() {
  usersController.init({
    urls: {
      deleteRecord: "...."
    }
  });
});

If I try to access state in the showDeleteConfirmation I get "ReferenceError: state is not defined" — gigi, Apr 02 '17 at 16:30
Because state, init and showDeleteConfirmation are comma separated variables. (members and functions) — gigi, Apr 02 '17 at 16:37
works fine here accessing `state` https://jsfiddle.net/vqdcgyyz/ — charlietfl, Apr 02 '17 at 16:47
I don't see why it would work in `init` but not `showDeleteConfirmation`. Is it working in `init`? — jakeehoffmann, Apr 02 '17 at 16:48
how do you access that variable? Did I get you right that you're trying to do it like `this.state`? I understand that's wrong but think that needs to be clarified:) — Yaroslav Grishajev, Apr 02 '17 at 17:15
I simply use "state" to access it. I mentioned above what happens if I use "this.state". — gigi, Apr 02 '17 at 17:19
Weird thing, i stopped inside "showDeleteConfirmation" with "debugger" and I could not access "state" but if I put an alert there, I can access the variable. — gigi, Apr 02 '17 at 17:27
@charlietfl Please move your comment inside an answer so i can accept it. Thank you! — gigi, Apr 02 '17 at 17:27

The variable state is available anywhere inside usersController

Try:

showDeleteConfirmation = function(recordId) {
      console.log(state);
};
