Trigger event with infoWindow or InfoBox on click Google Map API V3

erin picture erin · Aug 24, 2012 · Viewed 54.1k times · Source

I want to know how to trigger an event when I click on an infoWindow using Google Maps API v3. In this example, when I click on a marker, an info window shows up with a unique message, based on which marker I clicked. I want to also be able to click the info window and have an alert show up that says

"You clicked on the infowindow for (__fill in blank location_)

I found some examples using Google Maps API v2 and jQuery, but not with just plain old Google Maps API v3.

Update I ended up figuring this out for InfoBox as well, which is included below in my answer.

Ok I figured this out for infoWindow, but then I also figured it out for InfoBox since it is prettier and more customizable. I'm new to JavaScript and these closures can be very tricky.

For infoWindow
