You can now parse JSON data in BrightScript using the ParseJson global function. Incoming JSON strings can be converted into scripting elements such as objects, integers, or Booleans, thereby increasing the interactive and dynamic capabilities of networked BrightSign players. A full description of this new function can be found in the “Global Functions” chapter of the BrightScript 3.0 Reference Manual, available on the Documentation page.
Note that this is a developer resource. It is only available through custom scripts, not in BrightAuthor.
