Using JSON StringOf with Non-String Members

See more JSON Examples

If a JSON member is a boolean, integer, or null, using StringOf will return its string representation. Visual FoxPro

LOCAL loJson
LOCAL a
LOCAL b
LOCAL c
LOCAL lnIval
LOCAL lnBval
LOCAL lnHasNull

*  Create JSON with members of different data types.
loJson = CreateObject('Chilkat.JsonObject')

loJson.UpdateInt("a",123)
loJson.UpdateBool("b",1)
loJson.UpdateNull("c")

loJson.EmitCompact = 0
? loJson.Emit()

*  Resulting JSON:
*  {
*    "a": 123,
*    "b": true,
*    "c": null
*  }

a = loJson.StringOf("a")
? a

b = loJson.StringOf("b")
? b

c = loJson.StringOf("c")
? c

*  Output

*  123
*  true
*  null

*  If you want to get the integer, boolean, or null value
*  you need to use the methods matching the data type
lnIval = loJson.IntOf("a")
lnBval = loJson.BoolOf("b")
lnHasNull = loJson.IsNullOf("c")
