jQuery JavaScript Detect object in view / window
<p>Ok, this may have been asked dozens of times over. But I'm not exactly sure what technique or term I would have to search for in order to find out more information on this.</p>

<p>What I have is an Unordered list of Elements. Each one acting as a screen on a project I am working on. Each element is the size of the browser window, so its more like a power point presentation then anything if I were to describe it in any sense of the logic I have here. So what I am trying to do is find out when any particular slide is active in the view. One I have a few images I would like to load only when the view is active. But what I am really looking for is to highlight the navigation according to the slide I am on. The navigation is a fixed element so its always on the screen while everything else just floats on in, in a matter of speaking. Another reason I need this is, the navigation doesn't come into effect until the second slide. So I need a way to trigger the navigation into displaying itself only when every slide other than the first one is in view, and I will remove it when the first slide is in the view.</p>

<p>Hopefully I made some sense on this, anyone have any idea's?</p>
