Example
Rem JSON.parse Example
Dim s = "{""a"": ""this is string a"", ""b"": 99}"
myObject=JSON.parse(s, reviver)
Print "myObject.a:" & myObject.a & " myObject.b:" & myObject.b
Function reviver(key, value)
If key="a" and TypeName(Value)= "Integer" Then
reviver=CStr(value) 'If value is a number, we want to change it to string.
Else
reviver=value
End If
End Function
Output
myObject.a:12355 myObject.b:4
