Fires after the JSDO, by means of a saveChanges( ) call following a remove( ) call, sends a request to delete a record in the Data Object resource and receives a response to this request from the server.
This event fires after the response from a Delete operation request (sent without using Submit) has been received, and fires after the response from a Submit operation request for each one of possibly multiple record deletes has been received.
Note: A single Delete operation request is sent for each record object that you have deleted in the JSDO with a single call to saveChanges( ) or saveChanges(false). A single Submit operation request for any and all created, updated, and deleted JSDO record objects is sent with a single call to saveChanges(true).
The following parameters appear in the signature of any event handler (callback) function (or functions) that you subscribe to this event:
Syntax
function ( jsdo , record , success , request )
jsdo
A reference to the JSDO that invoked the delete request. For more information, see the description of jsdo property of the request object.
record
A reference to the table record upon which the delete request acted. For more information, see the description of jsrecord property of the request object.
success
A boolean that is true if the delete request was successful. For more information, see the description of success property of the request object.
request
A reference to the request object returned after the delete request completes. For more information, see the description of request object.
Application code can subscribe a callback to this event by invoking the subscribe( ) method on a JSDO instance or one of its table references.
Example
The following code fragment subscribes the function, onAfterDelete, to handle the afterDelete event fired on the JSDO, myjsdo, created for a single-table resource, ttCustomer, where myid is the known ID of a record to find and delete:
/* subscribe to event */
myjsdo.subscribe( 'afterDelete', onAfterDelete );
/* some code that might delete one or more
records, then remove them on the server */
var jsrecord = myjsdo.findById(myid);
if (jsrecord) {jsrecord.remove();};
. . .
myjsdo.saveChanges();
function onAfterDelete ( jsdo , record , success , request ) {
var myField,
lenErrors,
errors,
errorType;
if (success) {
/* for example, get the values from the record that was
deleted to display a confirmation message */
myKeyField = record.data.myKeyField;
. . .
}
else { /* Handle Delete operation errors */
errors = jsdo.ttCustomer.getErrors();
lenErrors = errors.length;
for (var idxError=0; idxError < lenErrors; idxError++) {
switch(errors[idxError].type) {
case progress.data.JSDO.DATA_ERROR:
errorType = "BI Data Error: ";
break;
case progress.data.JSDO.RETVAL:
errorType = "Server App Return Value: ";
break;
case progress.data.JSDO.APP_ERROR:
errorType = "Server App Error #"
+ errors[idxError].errorNum + ": ";
break;
case progress.data.JSDO.ERROR:
errorType = "Server General Error: ";
break;
}
/* Log error type and message for current error */
console.log("ERROR: " + errorType + errors[idxError].error);
if (errors[idxError].id) { /* Log info for error with record object */
console.log("RECORD ID: " + errors[idxError].id);
/* If the error record ID matches the operation
record ID, log the record data values */
if (errors[idxError].id == record.getId()) {
console.log ("Customer Record Fields:");
console log (" CustNum = " + record.data.CustNum);
. . .
}
}
/* Log additional HTTP text for web or other server errors */
if (errors[idxError].responseText) {
console.log("HTTP FULL TEXT: " + errors[idxError].responseText);
}
}
} /* End Delete operation errors */
};
