Insert JSON Object into another JSON Object

See more JSON Examples

Demonstrates how to insert one JSON object into another. Effectively, the JSON object must be copied into the other.. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test

    Get pvComObject of hoJsonB to vJsonB
    Get ComAddObjectCopyAt Of hoJsonA 1 "info" vJsonB To iSuccess

    Get ComEmit Of hoJsonA To sTemp1
    Showln sTemp1

    // The result is this:
