afterInvoke event
afterInvoke event
Fires after a non–built-in method is called asynchronously on a JSDO and a response
to the request is received from the AppServer. Synchronous method calls do not cause
this event to fire.
Applies to: progress.data.JSDO class, invocation method
The following parameters appear in the signature of the event handler function:
Syntax
function ( jsdo , success , request )
jsdo
success
request
A reference to the JSDO that invoked the method. For more information, see the
description of the jsdo property of the request object.
A Boolean that is true if the operation was successful. For more information, see
the description of the success property of the request object.
A reference to the request object returned after the operation completes. For more
information, see the description of the request object.
Example:
myjsdo.subscribe('afterInvoke', 'myMethodName',
onAfterInvokeMyMethodName);
myjsdo.myMethodName( paramObject);
function onAfterInvokeMyMethodName(jsdo , success , request )
if (success) {
var response = request.result.response;
};
var retval = response._retval;
var myOutputParm = response.myOutParam;
}
else {
if (request.response && request.response._errors &&
request.response._errors.length > 0){
var lenErrors = request.response._errors.length;
for (var idxError=0; idxError < lenErrors; idxError++) {
var errorEntry = request.response._errors[idxError];
var errorMsg = errorEntry._errorMsg;
var errorNum = errorEntry._errorNum;
/* handle error */
}
}
}
