Unit MyTest;

procedure Run; async;
begin
  // do something...
end;

begin
   run()._then(function (a : jsvalue) : jsvalue
     begin
     end);
end.

In the line "run()._then(function (a : jsvalue) : jsvalue” give me the error “Error: illegal qualifier "." after " run():Procedure/Function"”

Subject: [Pas2js] Async procedure.
Message-ID:
        <CP4P284MB0994AF032625620A0E1D1FD2B23F9 at CP4P284MB0994.BRAP284.PROD.OUTLOOK.COM>

I'm making a remote request client and I had a problem.

I declared an asynchronous procedure, but it doesn't generate a promise.

This I can't register the "then” event.

Is it possible to modify this procedure behavior?

Works fine here:

uses JS;

function Run: word; async;
begin
   Result:=3;
end;

begin
   run()._then(function (a : jsvalue) : jsvalue
     begin
     end);
end.

or

uses JS;

function Run: word; async;
begin
   Result:=3;
end;

var
   p: TJSPromise;
begin
   p:=Run(); // calling directly without await() returns a TJSPromise!
   p._then(function (a : jsvalue) : jsvalue
     begin
     end);
end.

So what does not work for you ?

Michael.
