Webview onResult for multople eval functions

esferatec

I am exploring the webview control and creating a rich text editor with Quill. I am accessing the Quill library API with several "Webview:eval(expr)" methods.

Is it possible to assign a specific function/event to the "Webview:eval(expr)" method - like "Webview:eval(expr, function)"? Currently every "Webview:eval(expr)" always calls the same "Webview:onResult(result)" event. At the moment I can only see from an application variable which actions are to be executed.

Or could you add another parameter to the "Webview:onResult(result)" event - Webview:eval(expr, option) - and pass this parameter to the "Webview:onResult(result, option)" event.

Hi esferatec,

It's a very good request.
This design is not very good I agree, and was designed before Tasks had been implemented.

I will see what I can do, maybe using a Task object will be possible.

It's done ✅
In next LuaRT version, the onResult event will be replaced by a Task instance returned by the Webview:eval() method.

It's very cool to write those kind of statements :

Webview:eval("Math.PI").after = function(value)
    ui.info(value, "Math.PI value from Javascript")
end

Thank you Esferatec for your feedback on this !
