Access values returned after form submit

Hi everyone,

I submit a form.
My server returns a 200 response, along with some variables in a JSON format.
That’s all normal.

How do I access those variables? I want to pop up a message that depends on the variables value… but I’m having a brain-fart or something. I cannot for the life of me access it on the user side.
