Parse a GOT result from AsteroidDB

MIT App Inventor Help
1

I use the extension of AsteroidDB. I can store a value with call AsteroidDB1.Store.
But how can I get the value of the Tag and save it into a variable or lable.
How is the best way to parse out the GOT result for example {“action”:“GOT”,“tag”:“score”,“value”:“4”}.
I need the value.
I find a complex solution

But does there exist also an easy way.
kindly regards

Use the dictionary blocks (get keys/values etc)

You may need the Dictionary from JSON block in the web component to convert the plain script JSON coming back from the database…

what have you tried?

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
