Retrieve graphics from third party vendor ESRI JS API app

Anonymous User — Thu, 26 Oct 2017 17:30:20 GMT

Hi all,

Is there a way for me to retrieve all the graphics (polygons) that my client drew and stored in his app (codered) to a local database or shapefile? Using the debugging tool in chrome I can get the path in the CSS but I cannot get the graphics layer itself. Any tips?

path: path('M 1004 156 L 100...‍d="M 323 194 323...)‍

Alex,

I am not sure why you can not get the graphics from the clients map. If they drew the paths on the map then normally this would be done using the Draw and it creates graphics that you can convert into json and then use a web service or something to send to the database.

Ok, How would I access the JSON of the graphics layers?

Alex,

You loop through the graphics in the GL and use the Graphics.toJson method:

Sorry Robert, that does make sense if I had the app code source and could modify the script to convert objects to JSON but here the web map is hosted on a platform somewhere else. How should loop through the GL on a client web site? Using Google Chrome?

I am not aware of anyway to do that.

OK. Thank you anyway. I would like those graphics to become a feature service eventually. But I dont think that can happen unfortunately. Or, I may have to work with the vendor for that.
