I am familiar with Jquery AJAX call, which has different callbacks like beforeSend, success, complete, etc.

This is the example AJAX call with Jquery:

$.ajax({
  url: 'register.php',
  type: 'POST',
  data: {name:name, email:email},
  beforeSend: function() {
       // show loading GIF
  },
  complete: function() {
      // hide loading GIF
  },
  success: function(data) {
      // parse response
  }
});

I want to achieve the same using AngularJS.

Is there a callback like beforeSend for AngularJS AJAX request ? This is my code so far, but i am not sure where can i use a callback like beforeSend (so that i can display a loading GIF image) in my code:

$http.post('register.php', {'name': $scope.name, 'email': $scope.email})
.success(function(data, status, headers, config) {
    if (data != '') { 
    }
});

You can use interceptors. Search for the word interceptor in the Angular $http documentation

As the documentation says : For purposes of global error handling, authentication, or any kind of synchronous or asynchronous pre-processing of request or postprocessing of responses

Here is a Fiddle Example displaying a loading gif before the ajax call is sent.

EDIT

As Satpal commented, $httpProvider.responseInterceptors used in the Fiddle is deprecated. You should use $httpProvider.interceptors instead.

I don't remove the Fiddle as it can give you an idea about how to implement it.

$httpProvider.responseInterceptors are DEPRECATED. You should provide example with $httpProvider.interceptors –  Satpal Mar 3 '14 at 7:13
