esponse property
response property
Returns an object whose properties contain data from a Mobile built-in or invoke
operation executed on the AppServer.
Data type: Object
Access: Read-only
Applies to: request object
If a built-in Mobile operation (create, read, update, or delete) returns successfully and
the response is valid JSON that can be converted to a JavaScript object, the response
property is a reference to the temp-table or ProDataSet object that is returned from the
AppServer. If the server response is not valid JSON, the response property is
undefined.
If an invoke operation returns successfully and has no return value or output
parameters, the property is null. If the invoke operation has a return value, you can
read it as the value of the object _retVal property. If the operation has output
parameters, you can read these parameters as the values of object properties whose
case-sensitive names and data types match the ABL names and data types of the
output parameters specified for the operation on the AppServer.
If the operation returns an ABL error, the object contains the following properties:
• _retVal — A String with the value of any ABL RETURN ERROR string or
ReturnValue property for a thrown AppError object
• _errors — An array of JavaScript objects, each of which contains two properties:
_errorMsg with the ABL error message string and _errorNum with the error
number, for one of possibly many ABL-returned errors
Note: In the current OpenEdge release, this array always returns one object only
for the first ABL error (the equivalent of ERROR-STATUS:GET-MESSAGE(1) in
ABL).
This request object property is available only for the following events:
• afterCreate
• afterDelete
• afterFill
• afterInvoke
• afterUpdate
