Timed Hyperlink Sample

Copyright Patrick Schmitz, 2003. You may freely use the associated information and may copy the HTML source, but not the media (which I borrowed from the MSDN samples).

Hyperlink elements can be timed with XHTML+SMIL (a.k.a. HTML+TIME), so that they are only sensitive to activation (usually by clicking on them), when the element is active.

The image below has an associated image map with <area> elements. Each <area> element has a two second duration, and is placed in a sequence that repeats.  The same timing is applied to a sequence of labels below the image, so that you can tell which area is currently active. If you click on a planet in the image, while the associated <area> is active, it will traverse a link to a larger image of that planet. If you click on any planet with an inactive <area> element, nothing happens. Note the cursor as you move over the planets - only the active link shows the pointer cursor.

In the HEAD a style block to bind the time behavior:

<style>
 .time, t\:* { behavior:url(#default#time2); }
</style>
		

The area elements have duration and are wrapped in a repeating sequence:

<t:seq repeatCount="indefinite">
