Writing Client Logic API Functions

Open the /sports-webui/ClientLogic/ folder in VS Code. Open Order/getOrderForeignKeys.js from the Explorer view (see picture below).

1. Replace 

   if (akioma.samples)
       akioma.samples = {};

   akioma.samples.getOrderForeignKeys = function(self) {

   With

   namespace akioma.samples {

       export function getOrderForeignKeys(self) { 

   Use namespaces to avoid naming conflicts. Note that functions must be exported to be used outside the namespace.
   
   

2. Replace self with eventSource: akioma.swat.SwatObject.
   
   Note that the function parameter name does not have to be eventSource. For example: eventGrid eventForm, eventRibbon etc. Although self might be confusing with the JavaScript dynObject.
   
   Note that the function parameter type does not have to be the generic base SwatObject as in this case. Use the correct Object Type class to avoid casting.
   
   
3. Replace getObject("CustomerDetailsForm") with getForm("CustomerDetailsForm"), getObject("CustomerGrid") with getGrid("CustomerGrid") and container with window.
   
   The CLA supports generic traversing functions like getObject(), getLink() etc. which return the generic base SwatObject class object.
   
   The CLA also supports type specific function like getForm(), getGrid(), getRibbon() etc. to avoid casting.
   
   Alternatively you can use TypeScript casting. For example: (eventSource.getObject("MyObject") as akioma.swat.Form).
   
   
4. Replace getValue with getDataValue.
   
   The Form and Grid classes have both a getScreenValue() and getDataValue() functions for getting the field screen value or record value respectively.
   
   Save (Ctrl-S) and rename (F2) the file as Order/getOrderForeignKeys.ts using the .ts TypeScript file extension (see picture below).

Note that for the changes to take effect you will need to do a hard refresh on the web page (Ctrl-F5).

...

Open DevTools (F12) in your Sports Application environment. Open the getOrderForiegnKeys.ts file (Ctrl-P) in the Sources tab (see picture below).

You can turn off source maps in DevTools to view the underline JavaScript code which would also allow you to edit the code.
