B4J Question ws.RunFunctionWithResult

[Blueforcer]

Hello,
Im really new in Webapp development.
For my current Project i need to get all IDs from the current document.
this is the working javascript function:

document.querySelectorAll('*[id]')

But how i have to do it in B4J?
This one dont work.

Dim F As Future = ws.RunFunctionWithResult("document.querySelectorAll",Array As Object("*[id]"))

thank you in advance

RunFunction runs a JavaScript function. You need to use EvalWithResult.

that doesn't work either. Value is still Null
But before we look for the mistake:
is it even possible to access these elements at the end without having declared them explicitly beforehand? Because I have several HTML pages that are dynamically generated by another program. Each element has a unique ID. But I just want to read/describe the elements that are currently present on the called page. So I would also need a way to react to all events of the "unknown" IDs.

You can run any JavaScript code you like.
