This method returns the next changed record in a grid. The record data can then be accessed through global fields, a data structure, or a return value object.
Parameters
Data structure (optional) - A Profound.js data structure reference. If specified and a record is found, the referenced data structure will be populated with the record data. If not specified, the data is populated into global fields.
Return Value
If a record is found, this method returns an object containing the fields in the matched record as properties.
pjs.defineDisplay("display", "subfiled.json", { rrnFields: { sfl: 'RRN' } });
// Load subfile grid data here
display.ctl.execute(); // display control record
// Now process all subfile grid records changed by the user
display.sfl.readChanged();
while (!display.endOfData()) {
// Process changed subfile records here
display.sfl.readChanged();
}
