Q:

Is there a way to call [ScriptableMember] in Asp.Net via jQuery

I know there's a way to call [WebMethod] via jQuery ($.ajax(...))
I was wondering if it's possible to call [ScriptableMember] via jQuery.

A:

It's just javascript. Maybe not the jquery ajax method, but that doesn't really mean much.
Some plugins do have calls to the ajax method built in, but they're usually not too hard to modify if necessary.
