I have purchased Web Server eBook and implemented all examples from the book on my ESP32. I am building a watering control system and have developed a web page for input of the watering settings. This is adapted from Section 4.1 – Web Server with Input fields (HTML form). I now want to display the results from the input process back to the web page.
This requires a string in the c++ main.cpp code to be passed back through Java Script to a ‘card’ container on the web page.
I have not been able to find an example that shows this use case.
Appreciate any ideas on where to look for information (spent many days trolling through Google searches).
