Ajax Navigation2

JavaScriptSource Staff Dec 6, 2006

General

When a visitor clicks on a specific link, the content of that link is inserted into the page without a refresh. When a page doesn't exist, a user-friendly error message is given. [Note: This is an edited version of the original script.]

My Navagation links

Go to page 1
Go to page 2

22. From: Erick[br /][br /]I have the exact same problem![br /][br /]Script works fine for static sites. But the caching is a pain for dynamic sights!

This seems to only work for pages that exist on your own database. Is there a way to get it to work for external sites?[br /][br /]I have only tested this on FF2.0.0.9
