My methods always alert Object [Object object]

Question

I don't know why the methods returns always [Object object]. My code it's here:

function SetDataDB(){
    alert(new DatabasePlugin.get_account_profiles('settings_account'));
}

var DatabasePlugin = {
    insert_account_profiles : function(array, parameter){
        window.localStorage.setItem(parameter, array);
    },

    get_account_profiles: function(parameter){
        return "Hola";
    }
};

It always returns me an object but not specified. What do I have to do?

@AlexK. the methods are on different classes so i need the new — Marc Ortiz

@MarcOrtiz Which, when instantiated, gives you an object :) What seems to be the problem? — user1726343

removing new gets you the string, as it stands its acting as a constructor so returns an object that is a new instance of get_account_profiles (which will show as [object object] if converted to a string) — Alex K.

Try this:

function SetDataDB(){
    alert((new DatabasePlugin).get_account_profiles('settings_account'));
}

I'm assuming the get_account_profiles of a DatabasePlugin instance returns a string.

EDIT: As per your edit, you need to define the object before you access its properties. Make sure DatabasePlugin is accessible in the scope you are invoking SetDataDB in.

it says me: object is not a function

@MarcOrtiz That means DatabasePlugin isn't a class, it is an object.

Yes it's an object. Because of this i didn't write the ()
