Can you pass parameters to an AngularJS controller on creation?
Notes:
This answer is old. This is just a proof of concept on how the desired outcome can be achieved. However, it may not be the best solution as per some comments below. I don't have any documentation to support or reject the following approach. Please refer to some of the comments below for further discussion on this topic.

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)
};
});
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.
