Example 7: Displaying the cursor location and using hotspots to switch regions and more!
This example illustrates the use of clickable regions on
the images that can trigger
loading a different file_of_filenames, show a pop-up message,
or present a different web page.
The location control has also been added to provide a display
of the curor's latitude and longitude. The coordinates
parameter, which defines the projection, is specified in each of
the 3 file_of_filenames.
Be sure to click on the white triangle(s) in the corner(s)!
Here is the very basic configuration file:
<![CDATA[
bottom_controls = startstop, overlay, looprock, step, speed, refresh, location
controls = framelabel
buttons_style=margin-left:10px;
active_zoom = true
overlay_static = y,n,y,n
overlay_zoom = y,y,y,n
overlay_labels = Topo/on, Radar/on, Counties/on, nesw/always
file_of_filenames = mpx_NCR_overlayfiles.txt
]]>
For those who want to switch file_of_filenames from their
own HTML, you can do that! Here's an example that you might
include on your page (with some styling, of course!):
<button onclick="HAniS.newFOF('mystuff/fof.txt')">Show New
File_of_Filenames</button>
