[jQuery] ajax load, url variable question.

[jQuery] ajax load, url variable question.


I am using the ajax load method to populate a select list.
$("#games").load("$siteRoot/file/ajaxgames.aspx",
{criteria.Platform.PlatformID: $(this).val(), view: "normal"});
what I am wondering is how I can get jquery to work with the var
"criteria.Platform.PlatformID"
I am doing it this way so I can pass a different var name depending on
the context, example "criteria.Platform.UrlName"
Any ideas?
Thanks, Mike
