Answer 1

I guess it has to do with what happens when Sololearn detects a form submit.
Instead of handling a submission request, why not get the value inputted in the textfield?

Answer 2

i didn't understand the last line you said,
and i didn't make this code in sololearn, i made it on my Linux machine, and it won't work in a normal browser, the same way it won't work in sololearn
