[javascript] Pass variables to AngularJS controller, best practice?

You could create a basket service. And generally in JS you use objects instead of lots of parameters.

Here's an example: http://jsfiddle.net/2MbZY/

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

app.factory('basket', function() {
    var items = [];
    var myBasketService = {};

    myBasketService.addItem = function(item) {
        items.push(item);
    };
    myBasketService.removeItem = function(item) {
        var index = items.indexOf(item);
        items.splice(index, 1);
    };
    myBasketService.items = function() {
        return items;
    };

    return myBasketService;
});

function MyCtrl($scope, basket) {
    $scope.newItem = {};
    $scope.basket = basket;    
}
