DesktopHTMLViewer.ExecuteJavaScriptSync(js As String) As Variant

New in 2021r3

Supported for all project types and targets.

Synchronously executes the passed JavaScript in the context of the currently loaded page and returns the result. Only strings and numbers may be returned.


Attempting to execute JavaScript before the page finishes loading (or if no page is loaded) is undefined and is unlikely to work.

In order to call JavaScript on Windows using the Native renderer, a document must already be loaded into the HTMLViewer. If no document is loaded, an HTMLViewerException is raised.
