AlloyUI: How to send an AJAX request

Just a short instruction on how to send an AJAX - request with AlloyUI. First you need to create an MVCPortlet so that you can fire to distinct methods.

Create an action method like this:

public void somethingHappensHere(
  ActionRequest actionRequest, 
  ActionResponse actionResponse) throws IOException, PortletException {
In your AlloyUI page add the following to a button of your choice. The variable "myActionURL" should point to your "somethingHappensHere" method in your portlet.
var url = '<%= myActionURL.toString() %>';
//this is the data that you are sending to the action method
data: {
   <portlet:namespace />id: selected,
   <portlet:namespace />name: name,
dataType: 'json',
on: {
  failure: function() { //do something },
  success: function(event, id, obj) { //do something else}
