table reference property (JSDO) table reference property (JSDO) A property on a JSDO that has the name of a temp-table mapped by the Mobile resource for which the current JSDO is created. Its value is a reference (table reference) to the temp-table object in JSDO local storage. This temp-table object provides access to the working record, if defined, of the temp-table. If a Mobile resource maps a ProDataSet, its JSDO provides one table reference for every temp-table in the ProDataSet. Data type: Temp-table object reference in JSDO local storage Access: Read-only Applies to: progress.data.JSDO class In syntax wherever a table reference can be used, table-ref represents the name of the property containing the table reference. A referenced temp-table object provides the following properties: • record property— A reference to a JSRecord object that has the data for the working record of the temp-table through a data property. If no working record is defined for the temp-table, the record property is null. • field reference property — A property on the temp-table object that has the name of a field (as defined in the temp-table schema) and the value for that field in the working record, also referred to as a field reference. In syntax wherever a field reference can be used, field-ref represents the name of the property containing the field reference. A temp-table object provides one field reference for each field defined in the original temp-table. If no working record is defined, all field references are null, except when fields are referenced on the data property of a JSRecord object reference. Caution: Never write directly to a field-ref using this record property or any JSRecord object reference; in this case, use field-ref only to read the data. Writing to data using such a reference does not mark the record for update when calling the saveChanges( ) method. To mark a record for update, you must assign a field value either by setting a jsdo.table-ref.field-ref for a working record or by calling the assign( ) method on a valid table-ref or JSRecord object reference. You can therefore reference the field values in the working record of a given table reference using either the JSRecord object returned by its record property or its field references. The field references provide a convenient way to access table fields that is similar to how you reference table fields in ABL. The record property provides an alternative way to access table fields, especially one that has the same name as a property or method of a JSDO that you can invoke from a table reference. For example, the following code fragment shows two different ways to access the CustNum field of a record added to a customer temp-table provided by a resource ProDataSet: var dataSet = new Progress.data.JSDO( 'CustomerOrderDS' ); dataSet.customer.add(); alert(dataSet.customer.record.data.CustNum); alert(dataSet.customer.CustNum); 254 OpenEdge ® Development: Mobile Applications
table reference property (JSDO) Both calls to the alert( ) function access the same CustNum field in the working record of the customer table created by the add( ) method. For more information on accessing the working record of a table reference, see the notes for the section on the progress.data.JSDO class.
