Hi

 

I want to display some Javascript component in a PB OLE Browser component. That works?

I receive clicked and doubleclicked events.

Is there a way to trigger PB events (anything) or event call PB functions from the Javascript execution flow ?

  2. JavaScript

Calling javascript or modifying the page from PowerBuilder is fairly straight forward:

To call PowerBuilder code from Javascript you can change the document title which would trigger the titlechange event in PowerBuilder. Since the web page is embedded on a window, you won't see it. Then in the titlechange event, you can have a case statement that looks at the value passed and determines what to do. The value would have a command code, a separator character and then some data.
