Olá pessoal, eu estava querendo um pop que travasse a página atrás e só tivessem acesso a página de trás quando fechassem o popup que está na frente.
Achei esse aqui no forum:
Para deixar mais claro, foi esse exemplo que usei: http://sublog.subimage.com/articles/2006/01/01/subModal
Ou senão, veja os codigos abaixo:
Só que o exemplo que me mostrou ele funciona com onclick, mas quando passo para onload ele da erro... Não abre, por que?
