Is there an asynchronous method for WebView1.InvokeFunction?

Hi,
You can try the same code in Chrome browser and you will see it returns a function. This is probably because the JavaScript engine treats a class and that's class's constructor the same.
The difference between JSObject and JSRealObject is JSObject also presents special value "Null" and "Undefined", where as JSRealObject will never be those two values.
There is no asynchronous version of JSObject.InvokeFunction. If you wish to run JavaScript code asynchronously, you can use WebView.QueueScriptCall.
Thanks!
