Can you pass parameters to an AngularJS controller on creation?

This also works.

Javascript:

var app = angular.module('angularApp', []);

app.controller('MainCtrl', function($scope, name, id) {
    $scope.id = id;
    $scope.name = name;
    // and more init
});

Html:

<!DOCTYPE html>
<html ng-app="angularApp">
  <head lang="en">
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.min.js"></script>
    <script src="app.js"></script>
    <script>
       app.value("name", "James").value("id", "007");
    </script>
  </head>
  <body ng-controller="MainCtrl">
    <h1>I am  {{name}} {{id}}</h1>
  </body>
</html>

I'm very late to this and I have no idea if this is a good idea, but you can include the $attrs injectable in the controller function allowing the controller to be initialized using "arguments" provided on an element, e.g.

app.controller('modelController', function($scope, $attrs) {
    if (!$attrs.model) throw new Error("No model for modelController");

    // Initialize $scope using the value of the model attribute, e.g.,
    $scope.url = "http://example.com/fetch?model="+$attrs.model;
})

<div ng-controller="modelController" model="foobar">
  <a href="{{url}}">Click here</a>
</div>

Again, no idea if this is a good idea, but it seems to work and is another alternative.

Original Answer:

I answered this to Yes you absolutely can do so using ng-init and a simple init function.

Here is the example of it on plunker

HTML 

<!DOCTYPE html>
<html ng-app="angularjs-starter">
  <head lang="en">
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.min.js"></script>
    <script src="app.js"></script>
  </head>  
  <body ng-controller="MainCtrl" ng-init="init('James Bond','007')">
    <h1>I am  {{name}} {{id}}</h1>
  </body>
</html>

JavaScript

var app = angular.module('angularjs-starter', []);

app.controller('MainCtrl', function($scope) {

  $scope.init = function(name, id)
  {
    //This function is sort of private constructor for controller
    $scope.id = id;
    $scope.name = name; 
    //Based on passed argument you can make a call to resource
    //and initialize more objects
    //$resource.getMeBond(007)
  };


});
