The content model you define should automatically be available to the JavaScript. For the example you mention, it should probably be something closer to:

var name=person.properties["userName"];

Take a look at a few script examples in Data Dictionary for inspiration.

There are also some good examples in JavaScript Cookbook:

I think i understand the source of confusion here. There are two types of JavaScipt that are possible - serverside javascript and client side. I thought you were talking about server side, where the person object should be available, and it seems like you are talking about client side. In that case, the person object is not available unless you make it available.

In 3.0, there is a REST API which you could call from your client-side javascript in order to get the data you need (many of these web scripts return JSON, so it should be quite easy).
http://wiki.alfresco.com/wiki/Repository_RESTful_API_Reference
http://wiki.alfresco.com/wiki/3.0_REST_API

Pre 3.0, there is no standard API available, but you could write one yourself to expose the person object through web scripts (possibly even backport some of the webscripts from 3.0).

var name=person.properties["userName"];

What is the easiest way to get more informations about the available properties of a certain content model, e.g. "person"? Or to be more precise: how do I know, which properties a certain content model has?

Kind regards

Now I think that the Javascript API of Alfresco doesn't expose any methods for that.

For the Javascript API you can expose the DictionaryService of Alfresco extending the Mozilla Rhino engine:
http://wiki.alfresco.com/wiki/3.4_JavaScript_API#Adding_Custom_Script_APIs

In this way you have to extend the Alfresco Javascript API with a new Javascript object available in the scope of the script that is the following service:
http://dev.alfresco.com/resource/docs/java/repository/org/alfresco/service/cmr/dictionary/DictionaryService.html

As you can see the DictionaryService allows you to get all the information that you need

Hope this helps.
