那里有没有Ajax窗口框架？

I have a project with a lot of pop-up layering going on and while i will have one layer open, that layer will effectively serve as another window. I'm currently managing this with _json specific return pages that just return json objects and the layer acts on that. Each call from the layer is from a jquery .ajax call which processes the json and requests another page.I have a project with a lot of pop-up layering
