JSRecord object JSRecord object Properties Methods JSRecord is a JavaScript object that returns a record instance for any temp-table stored in the local storage of an associated progress.data.JSDO class instance (JSDO). Table 8: JSRecord object properties Member Events This object has no events. Brief description (See also the reference entry) data property An object containing the data for a temp-table record specified by a JSRecord object Table 9: JSRecord object methods Member assign( ) method (JSDO class) Brief description (See also the reference entry) Updates field values for a temp-table record specified by a JSRecord object getId( ) method Returns the unique internal ID for the specified temp-table record referenced in JSDO local storage remove( ) method Deletes the temp-table record specified by a JSRecord object Example The following example assumes that a JSDO is referenced by the jsdo variable, and that a UIHelper instance associated with that JSDO is referenced by the uihelper variable. The example creates a new record object and displays it, along with a message with credit information using properties of the record object: function addRecord() { var jsrecord = jsdo.add({Balance: 10000, State: 'MA'}); uihelper.display( ); alert('Record ID: ' + jsrecord.getId( ) + ' CreditLimit: ' + jsrecord.data.CreditLimit); } Note Using the add( ), find( ), findById( ), or foreach( ) method, or the record property, on a given JSDO and table reference, a JSRecord instance returns a working record for the temp-table referenced in JSDO local storage. You can then use properties and methods of the JSRecord to update, delete, or display the specified record from the JSDO.

progress.data.JSDO class progress.data.JSDO class The progress.data.JSDO is a JavaScript class that provides access to ABL application services as OpenEdge Mobile resources. A single progress.data.JSDO object (JSDO) provides access to one Mobile resource in an OpenEdge Mobile service. A Mobile resource maps to an ABL singleton procedure or class running on an OpenEdge AppServer. The JSDO provides application-oriented, JavaScript methods to invoke the internal procedures, user-defined functions, or methods (ABL routines) of the corresponding singleton procedure or class. A Mobile resource maps specified ABL routines as one of several supported Mobile operation types, each of which corresponds to a particular method of the JSDO. You identify how a JSDO maps JavaScript methods to operations of a given Mobile resource by adding annotations to the singleton procedure or class source code. These annotations define a Mobile interface for accessing the procedure or class as a Mobile resource. You can define a Mobile interface using features of Progress Developer Studio for OpenEdge (Developer Studio) in two ways: 1) when creating an ABL Business entity class, which supports common business operations on data models, and 2) for any existing ABL singleton class or procedure, whether or not the singleton accesses a separate Business entity object. You can also use Developer Studio to define a Mobile resource as part of a Mobile service, and to generate the Mobile service together with the client-side artifacts required to create a corresponding JSDO for the resource. These client-side artifacts include a JSDO catalog file that identifies how a JSDO that you create can access the corresponding Mobile resource using methods of the JSDO. At run time, the JSDO maintains local storage for managing temp-table data that is exchanged between the AppServer and JavaScript client, and it provides methods to read and write the data in JSDO local storage as individual JavaScript record objects. To support this data exchange, a Mobile resource can be organized into basic operation types that include built-in create, read, update, and delete (CRUD) operations, and non-built-in invoke operations. The built-in Mobile operations can operate on a single temp-table or on a single ProDataSet containing one or more temp-tables. Each built-in operation type maps to a corresponding built-in method of the JSDO. The records of each temp-table are presented as an array of record objects, which the built-in methods use to exchange the data with the AppServer. The built-in methods, through their corresponding operation types, support the common business operations that can be generated directly from an ABL Business entity. Other methods of the JSDO provide access to individual record objects of JSDO local storage. Based on the results of its methods, the JSDO also maintains a working record for each temp-table in its local storage that you can access directly using table and field references (see the notes). Thus, using the methods of a JSDO and its table references, you can interact with a corresponding Mobile resource in a consistent manner from one resource (and its corresponding JSDO) to another. A JSDO also supports non-built-in invoke operations that allow specific ABL routines to be exposed in a Mobile resource and executed as corresponding JavaScript methods. You can do this in Developer Studio by annotating ABL routines specifically as invoke operations. You can then call each ABL routine annotated as an invoke operation using a unique invocation method on the JSDO. Note that data exchanged between the AppServer and client using invoke operations is not automatically stored in JSDO local storage. It is initially accessible only through parameters and return values of the invocation methods provided by the JSDO. You can subsequently use JSDO methods for accessing JSDO local storage to exchange data between the invocation methods and local storage, which is maintained and synchronized with the AppServer using the JSDO built-in methods.
