Update the link to a KML file used by Google Maps when a button is clicked

On the initial page load, I want to showcase an 8 Day Average KML file on Google Maps. However, users should have the option to click on the "1 Day" and "3 Day" buttons to switch the reference in Google Maps from the "8 Day" file.

The aim is to design a simple template where users can input three sets of values: the H3 header text, the URL for the KML file used in Google Maps, and the HREF URL for downloading the KML file below the map. This template will be used on multiple pages displaying satellite images of different locations worldwide.

I am currently exploring ways to dynamically replace these values based on which HTML button the user clicks.

Answer №1

I have slightly adjusted the data for better clarity.

Ensure that you define map and ctalayers as global objects, then load the updated KML URL and display it on the map using the following code:

ctaLayer = new google.maps.KmlLayer({ url: kmlURL});
ctaLayer.setMap(map);

Complete example: http://jsfiddle.net/Rsp22/2209/

Answer №2

If you want to load three different KML files, you can do so by using three separate ctaLayers - ctaLayer1, ctaLayer3, and ctaLayer8. Then, you can use different buttons to trigger an onclick event that will call a specific function and set the corresponding ctaLayer. One ctaLayer will be set to the map while the others are set to null, like this:

ctaLayer3.setMap(map);
ctaLayer1.setMap(null);
ctaLayer8.setMap(null);
