Get and Set field using rtti

Hello everyone, does anyone know how to obtain the value of a field through rtti and modify the value through rtti, in webcore the Rtti unit is not recognized.

Somebody could help me? Thank you so much

I don't think you can as Rtti hasn't been made part of the Pas2JS library. You might be able to do something with raw javascript. What are you trying to do?

There is typinfo.pas and rtti.pas
I'm not sure what exactly you mean with "value of the field"? Is this a TDBField? Something else? Did you try typeinfo or rtti based code and if so, what exactly is the problem with it?
