Oprire utilizator cu confirmare la parasire pagina

[LCristian]

Slaut, am putina nevoie de ajutor, la ultimul "pas" al votului, clientul trebuia sa introduca codul captcha intr-un iframe dupa care de pe site-ul meu este redirectionat catre "top-ul" respectiv.(ex: xtremetop).
Am explicat cam aiurea. O poza sa fie ceva mai clar.


Cum as putea face a.i clientul sa nu fie "lasat" sa paraseasca pagina decat dupa ce votul este validat de catre "iframe" si pagina din el este redirectionata catre "top".

Multumesc

Salut
Cred ca se poate daca poti adauga cod in fisierul din iframe, adica o instructiune javascript care, atunci cand e adaugat votul, sa acceseze o functie din pagina parinte, folosind: parent.numeFunctie() (care de exemplu sa adauge un DIV transparent pe toata fereastra), iar dupa validare sa apeleze alta functie ca sa stearga acel DIV, si imediad face redirect.
Dar asta presupune sa ai access la codul paginii din iframe.

Nu am cum sa am acces la iframe. Totusi am vazut chestia asta la un alt site.
M`am uitat in sursa paginii lor si am luat asta: infusionconquer.com/insanity/code.txt

M-am uitat putin pe acel cod. Nu am inteles cine stie ce, dar poate functioneaza adaugand acest cod in pagina.

Cod: Selectaţi tot

- Si inlocuiesti in codul JavaScript: http://www.xtremetop100.com/in.php?site=1132330134 cu adresa ta de vot.

Primesc mesajul asta cand vrea sa "functioneze".
http://i39.tinypic.com/3532yw2.jpg

Din ce pricep, acel mesaj e codul HTML al paginii de votare. Dar nu cunosc de ce se intampla asa, nici nu am idee de ceea ce fac instructiunile din codul dat mai sus.
L-am testat intr-un document HTML nou si a mers, dar sa ma bag cu mintea in el ca sa stiu ce face si de ce, ma depaseste.

Alta metoda sa inchid pagina cand incearca sa fie redirectionata n`ar mai fi?
