浏览器助手对象和AJAX

Question

I am wondering if BeforeNavigate2 or DocumentComplete events should fire on pages with AJAX. For example google maps. When I put something in addressbar everything is ok, but when I move the map and resizing it nothing happens (DocumentComplete and BeforeNavigate2 does not fire), but data is sent to and from Internet.

Answer 1

The a in ajax stands for asynchronous. These events fire in response to synchronous methods completing. Since an asynchronous request can be made at any time the browser has no way of knowing when they are all completed.
