emove( ) method
remove( ) method
Deletes the specified temp-table record referenced in JSDO local storage. The
specified record can either be the working record of a referenced temp-table or any
record provided by a JSRecord object.
After execution, any working record for an associated temp-table, and for any child
temp-tables is not set. To synchronize the change on the AppServer, call the
saveChanges( ) method.
Return type: Boolean
Applies to: JSRecord object, progress.data.JSDO class, table reference property
(JSDO)
Syntax
[table-ref.]remove ( )
jsrecord-ref.remove ( )
table-ref
A table reference on the JSDO for a temp-table that has a working record. If the
JSDO references only a single temp-table, the method can be called on the JSDO
itself.
jsrecord-ref
A reference to a JSRecord object for a temp-table record in JSDO local storage.
The following code fragment shows a jQuery event defined on a delete button to delete
the record displayed in a customer detail form from the eCustomer temp-table
referenced in JSDO local storage:
dataSet = new progress.data.JSDO( 'dsCustomerOrder' );
$('#btnDelete').bind('click', function(event) {
var jsrecord = dataSet.eCustomer.findById($('#custdetail #id').val());
jsrecord.remove();
dataSet.saveChanges();
});
The form has been previously displayed with values from the same record. When the
button is clicked, the event handler uses the findById( ) method to find the original
record with the matching internal record ID (jsrecord) and invokes the remove( )
method on jsrecord to delete the record from eCustomer.
