how to pass form data as parameters along with callback function?

I have an extended question on "calling webservice" on angular js In this tutorial: https://teamtreehouse.com/library/angular-basics/services-in-angular/using-services-to-get-data

you mention about using callback. I am trying to call a http service with some parameters to update the url.

angular.module('todoListApp') .service('dataService', function ($http) { this.getTodos = function (callback) { $http.get('mock/todos.json').then(callback) } });

if I want to update the url based on a dropdown in html. how do i pass the parameter then to the service? I tried the following code but it does not work: angular.module('todoListApp') .service('dataService', function ($http) { this.getTodos = function (callback, newurl) { var url = 'mock/'+newurl+'.json'; $http.get(url).then(callback) } });

any help on this is appiciated.

If I'm understanding your question correctly, what you need to do is pass the 'dataService' as a dependency to the controller in which you are trying to use the url information from. Then from within that controller you call the .getTodos() method so that it has access to the scope in which your 'newurl' is originating.
