Buna ziua.
Am un formular cu validarea fiecarui cimp introdus si vreau sa afisez msg-urile de err (unde e cazul) in dreptul fiecarui cimp.

in linia:
Cod:
document.getElementById('showFailed").innerHTML = xmlHttp.responseText;

vreau ca 'showFailed' sa fie denumirea fiecarui cimp.

Am incercat diferite variante dar nu a mers.

Cum treb sa fac sa preiau var "fid" si 'showFailed' sa devina fid+"Failed"?

Iar atunci cind nr exista deja in DB vreau sa afisez datele direct in formular, la inceput inactive, iar daca apas un buton "MODIFICARE" ele sa devina active pt a putea fi modificate.

Si pt a schimba metoda GET cu POST mai treb sa setez ceva?

Multumesc anticipat.
