findById( ) method
The following code fragment shows a jQuery event defined on a save button to save
the current field values for a customer detail form to the corresponding eCustomer
record in JSDO local storage:
dataSet = new progress.data.JSDO( 'dsCustomerOrder' );
$('#btnSave').bind('click', function(event) {
var jsrecord = dataSet.eCustomer.findById($('#custdetail #id').val());
jsrecord.assign();
dataSet.saveChanges();
});
The form has been displayed with previous values of the same record. When the button
is clicked, the event handler finds the original eCustomer record by calling
findById( ) with the id attribute of the form ($('#custdetail #id').val()), which
is set to the internal ID of the record. The jsrecord.assign( ) method then updates
the record from the values of the corresponding form fields and saveChanges( )
invokes the resource "update" operation on the AppServer to save the updated record
to its data source.
