The following example demonstrates the functionality of the GetJSonObject( ) method.

The following is a sample JsonObject:

 

{   “CustOrder”: {     “CustNum”: 1,     “Name”: “Lift Tours”,     “NewCust”: false,     “Order”: {“OrderNum”: 82, “OrderDate”: “2010-09-20”}     ]   } }

The following code fragment uses the GetJsonObject( ) method:

DEFINE VARIABLE CustInfo AS LONGCHAR NO-UNDO. DEFINE VARIABLE myObj AS JsonObject NO-UNDO. DEFINE VARIABLE myOrderObj AS JsonObject NO-UNDO. DEFINE VARIABLE myLongchar as LONGCHAR NO-UNDO.   /* . . Set CustInfo to the JsonObjet shown above. . */   myObj = CAST(myParser:Parse(CustInfo), JsonObject). myOrderObj = myObj:GetJsonObject(“CustOrder”):GetJsonObject(“Order”). myOrderObject:Write(myLongchar, TRUE).

The following is the resulting myLongchar value:

 

{“OrderNum”: 82, “OrderDate”: “2010-09-20”}
