angularjs - Javascript outside angular js -

in angular js instead of using service in module, can create javascript functions outside controller , call when want to?

for example:

var urlpath="http://www.w3schools.com//angular//customers.php" //this contain functions  function testing_model ($http){  var self=this;   self.getrecords=function(){  $http({   method:'get',   url: urlpath,  }).success(function(data){   self.record=data.records; });  } self.getrecords(); }  angular.module("myapp", []); app.controller('mycontroller', function ($scope, $http) { $scope.testing_model = new testing_model();} 

when run code above, says "$http not function".

thanks in advance.

you need pass $http function...

$scope.testing_model = new testing_model($http); 

although work goes against idea of angular. must inject function service in controller write testable code, track dependencies , respect other developers going support project later.
