Tips for setting up a service, factory, or other component in AngularJS

I have a service that can handle four different types of http requests, but all return data following the same model structure. I am looking for advice on how to save the results from the service along with some specific data in my JavaScript Angular code.

Currently, I have implemented it by creating a factory that returns a new instance of a class storing the results and specific data.

app.factory('myFactory', function () {
    var myDataModel = function (name) {
        var self = this;
        self.name = name;
        self.results = [];
        self.isSearching = false;

        self.get = function (id) {
            self.isSearching = true;

            $http.get('url' + '?name=' + self.name + '&id=' + id)
                .then(function (data) {
                    self.results = data;
                    self.isSearching = false;
                });
        };

        self.display = function () {
            alert('the result of ' + self.id + ' is:' + self.results.join(', '));
        };
    };
   
    return {
        myDataModel: function () {
            return new myDataModel();
        }
    };
});

I'm unsure if this approach is the best way to do it. I would appreciate suggestions on other implementation methods like using a service or directive instead.

Thank you!

In my opinion, the approach you are taking to create this service seems more suited for a Service rather than a factory, although it could still work.

If I were to write this as a factory, I would do it like this without using the 'new' keyword:

app.factory('myFactory', function () {
var myDataModel = {};

myDataModel.name = name;
myDataModel.results = [];
myDataModel.isSearching = false;

myDataModel.get = function (id) {
myDataModel.isSearching = true;

$http.get('url' + '?name=' + myDataModel.name + '&id=' + id)
    .then(function (data) {
         myDataModel.results = data;
         myDataModel.isSearching = false;
    });
};

myDataModel.display = function () {
    alert('the result of ' + myDataModel.id + ' is:' + myDataModel.results.join(', '));
};
return myDataModel;
});
