I'm sorry but I can't figure it out myself that, what is the point of 'ajaxpage'?
Why should you do that? I really want to hear your side of story

Yap, i agree with kamiphuc. It's really hard to read this without an explanation and code-intendation. It seems you're loading multiple pages via AJAX. Maybe it would be better to load templates once, and the content as JSON if you need it. Then you could use a client-sided templating-engine like mustache.js or handlebars.js. By the way, what are those 'externals/graphic/graphic*.html'-pages looking like?
