public class JavaScriptApi extends Object
Base class for JavaScript API wrappers providing access to browser functionality from server-side Java code.

This class provides the foundation for all JavaScript API classes in the Oorian framework. It includes the core executeJs methods for executing arbitrary JavaScript on the client, as well as utility methods for obtaining the current page context.

All methods are provided in two forms:

  • Convenience form - No page parameter; uses thread-local page lookup
  • Efficient form - Accepts page parameter; avoids thread-local lookup

Usage:


 // Convenience - uses thread-local page lookup
 JavaScriptApi.executeJs("console.log('Hello')");

 // Efficient - passes page reference directly
 JavaScriptApi.executeJs(this, "console.log('Hello')");
