Accessing complex data properties on the client side.

I'm trying to access the properties of an object passed back from a web service but am having trouble. I thought the syntax was...

results.getItem(i).getProperty(

'propertyname') but I'm getting an error 'results.getItem(i).getProperty' is not a function.

I'm able to bind 'results' to a listview fine on the client side and debug.dump shows the data being returned is correct.

i don't know what type 'results' is.
you can try to use code below to list methods and propertis of getItem(i)
function(obj)
{
for(var name in obj)
names+=name+"\n";
alert(names);
}

Sorry tonyqus, 'results' is a generic collection and the javascript function on the client returns '_serverType' and the property names of the objects (similar to debug.dump). If I return a datatable the following works fine.

for (var i = 0; i < results.get_length(); i++) { alert(results.getItem(i).getProperty("PropertyName"));}

Is there a way to do something similar with object collections? The object collection binds fine to a listview or select element using set_data(results) so there must be some way of referencing the properties in javascript.

Never mind:!

Came back to it today and looked a little closer at the response from fiddler for a datatable vs an object collection. Also looked a little closer at JSON (http://www.json.org/). The line results.getItem(i).getProperty("PropertyName") works with datatables where results[i].PropertyName works with collections.
