Answer 1

Use service to share the data between controllers. Inject the service to both controllers.

app.service('userService', function() {

    this.userId = '';

    this.setUserId = function(id) {
        this.userId = id;
    };

    this.getUserId = function() {
        return this.userId;
    };

}
