The method returns an object that ... by the Google maps API code. Note that in JavaScript (unlike some other programming languages like Python) each statement must be ended with a semicolon. Also note that objects are often passed directly to functions without being assigned a name first.

You'll probably want to be doing this server-side using something like PHP.

I would personally be extracting the EXIF data, filename, etc. using PHP and then storing those in a database. Then call that info out to an array in your Javascript and iterate through those to create your markers.

I'm not on a computer where I can grab you the exact code, but if you look at https://developers.google.com/maps/documentation/javascript/markers#maps_marker_simple-javascript

Add latitude and longitude arguments to that function, and iterate through them for each of the markers you need to add.

Using Google Maps JavaScript API to auto populate form fields / Has anyone integrated Gravity Forms?

June 7, 2022 - the short answer is YES, you could have code that sat inside the whenRendered() function of the form that called out to google maps (or any other API for that matter), and pushed values into the fields. I'd have expected (assuming you've done all the set up stuff in Google Maps already) that this would be very straightforward (if you want a t-shirt size estimate, I'd say this was an S).

There is some closure magic happening when passing the callback argument to the addListener method. This can be quite a tricky topic if you are not familiar with how closures work. I would suggest checking out the following Mozilla article for a brief introduction if it is the case:
