Can't call JavaScript

[GirkovArpa]

JavaScript cannot be called when using the Sciter.JS library. Nothing happens, except it returns Ok(undefined).

fn document_complete(&mut self, root: HELEMENT, _target: HELEMENT) {
  let value = &Element::from(root).call_function("foo", &make_args!("bar"));
  println!("{:?}", value); // Ok(undefined)
}

http://sciter.com/forums - better to ask there. Sciter.Js have some surprising decisions, so no idea what is working on that version and what isn't.

[GirkovArpa]

Very well then.

[GirkovArpa]

The workaround I'm using is, since JS can call Rust but not vice-versa, is have JS simply keep asking Rust if it needs to do anything, and act based on the response.

[pravic]

Not an efficient decision. What was the answer on sciter forums?

[GirkovArpa]

I have not asked yet 😛

I got it to work with:

let root = Element::from_window(frame.get_hwnd()).unwrap();
root.eval_script("Window.this.Test()").unwrap();

Got it working with this:

impl sciter::EventHandler for EventHandler {
    fn get_subscription(&mut self) -> Option<sciter::dom::event::EVENT_GROUPS> {
        Some(
            sciter::dom::event::default_events()
                | sciter::dom::event::EVENT_GROUPS::HANDLE_METHOD_CALL,
        )
    }
}

@GirkovArpa Wait, the title says "cannot call JS" and you are talking about "cannot be called from JS".
Also, default_events() does include HANDLE_METHOD_CALL by default:

rust-sciter/src/dom.rs

Lines 1487 to 1489 in f59030a

 pub fn default_events() -> EVENT_GROUPS { 
 	return EVENT_GROUPS::HANDLE_BEHAVIOR_EVENT | EVENT_GROUPS::HANDLE_SCRIPTING_METHOD_CALL | EVENT_GROUPS::HANDLE_METHOD_CALL; 
 }
