asp datatypes converted to JSON

[michal]

hi guys,
i thought you might be interested in a nice JSON class which converts
ASP datatypes (basic datatypes, dictionaries, recordsets, ...) into
JSON so that javascript can easily understand it ...
you'll find the demonstration and the download here

Ummm - ASP is not a language with datatypes. Perhaps you meant
"vbscript". You also seem to forget that ASP can use other scripting
languages such as jscript. You might want to update your page.

You might find refactoring that generateValue function into several
smaller functions worthwhile. I have a function I use for debugging
which looks like this:

Function Repr(val)
Dim r
Select Case False
' For Scalars and objects other than Err, the name of the Repr
' function can be derived directly from the value's type
Case IsObject(val), val Is Err
On Error Resume Next
Set r = GetRef("Repr::" & TypeName(val))
On Error Goto 0
' The type of the Err object is "Object", so its Repr function
' must be manually chosen
Case Else
Set r = GetRef("Repr::E rr")
End Select

If IsEmpty(r) Then Repr = TypeName(val) Else Repr = r(val)
End Function

Then simple specialized functions for each data type can be defined:

Function [Repr::Integer] (val)
[Repr::Integer] = "CInt(" & val & ")"
End Function

Function [Repr::Date] (val)
[Repr::Date] = "#" & val & "#"
End Function

Function [Repr::String] (val)
[Repr::String] = """" _
& Replace(val, """", """""") _
& """"
End Function

Function [Repr::Boolean] (val)
[Repr::Boolean] = CStr(val)
End Function

Function [Repr::Variant()] (val)
With CreateObject("S cripting.Dictio nary")
Dim elm: For Each elm In val : .Add .Count, Repr(elm) : Next
[Repr::Variant()] = "Array(" & Join(.Items, ", ") & ")"
End With
End Function

This allows you to easily define Repr functions for user-defined types:

Class Foo : End Class

Function [Repr::Foo] (val)
[Repr::Foo] = "New Foo"
End Function

You should be able to use a similar strategy to emit JSON-encoded data.

Re: asp datatypes converted to JSON

hi justin,
thanks really for your reply, cause as i can see i can still discover
something new in Vbscript... i havent seen the getRef function yet..
its awesome.. will play around and this might be a good refactoring
suggestion ;)
thanks!
