Sometimes it is necassary to combine to JSONs, search for a special member by key or copy a json in a new one.

Exampleimplantation for SetActiveJSONMember() and CombineJSONMember() (include value2 in value1)
For Copy create a empty JSON and use it as first Parameter in combineJSONMember()

Code: Select all

Declare CombineJSONMember(Value1,Value2)
  Procedure SetActiveJSONMember(ObjectValue,name.s)
    Protected ret
    If ExamineJSONMembers(ObjectValue)
      While NextJSONMember(ObjectValue)
        If JSONMemberKey(ObjectValue)=name
          ret=JSONMemberValue(ObjectValue)
          Break
        EndIf
      Wend
    EndIf
    ProcedureReturn ret
  EndProcedure
  Procedure _InsertArray(newva,jmv2)
    Protected count1,count,i,Element,NewElement
    count1=JSONArraySize(newva)
    count=JSONArraySize(jmv2)
    For i=0 To count-1
      Element=GetJSONElement(jmv2,i)
      If i<count1
        RemoveJSONElement(newva,i)
      EndIf
      NewElement=AddJSONElement(newva,i)
      Select JSONType(element)
        Case #PB_JSON_Null
          SetJSONNull(NewElement)
        Case #PB_JSON_String
          SetJSONString(NewElement,GetJSONString(Element))
        Case #PB_JSON_Number
          SetJSONDouble(NewElement,GetJSONDouble(Element))
        Case #PB_JSON_Boolean
          SetJSONBoolean(NewElement,GetJSONBoolean(Element))
        Case #PB_JSON_Array
          SetJSONArray(NewElement)
          _InsertArray(NewElement,Element)
        Case #PB_JSON_Object
          SetJSONObject(NewElement)
          CombineJSONMember(NewElement,Element)
      EndSelect
    Next     
  EndProcedure
  Procedure CombineJSONMember(Value1,Value2)
    Protected newva
    Protected jmv2
    Protected jmk2.s

      While NextJSONMember(Value2)

          Case #PB_JSON_Null
            newva=AddJSONMember(Value1,jmk2)
            SetJSONNull(newva)
          Case #PB_JSON_String
            newva=AddJSONMember(Value1,jmk2)
            SetJSONString(newva,GetJSONString(jmv2))
          Case #PB_JSON_Number
            newva=AddJSONMember(Value1,jmk2)
            SetJSONDouble(newva,GetJSONDouble(jmv2))
          Case #PB_JSON_Boolean
            newva=AddJSONMember(Value1,jmk2)
            SetJSONBoolean(newva,GetJSONBoolean(jmv2))

              SetJSONArray(newva)
            EndIf
