I need to create a simple hover using openlayers for worldwide airport data. I'm thinking maybe the associated address, maybe a picture in regards to the airport, ...anything really. It's just an html file with some js, nothing too crazy but I've been out of the GIS/coding game for a while.
This is the current code for the html file. As you can see, there is an associated map file. Since there are so many airports, I'm guessing you would want to put the code in the mapfile (in regards to the hover(s))
Here is the map file. Apologies in advance for a little screwed up indentation.
So I guess my main question is: do I need to be messing with the map file or just the html? I found another example where they were referencing the hover in the map file but that example was not also a straight html file...if that makes sense. I looked through the openlayers documentation but it was pretty tough to grasp.
Any input is greatly appreciated.
