"Done with Errors'' sur IE mais pas sur FF
Bonjour a tous,
j'ai un petit module qui me permet de creer une ligne dans une table. je cree les lignes dynamiquement avec JS. et ensuite quand je soumets le formulaire, je reaffiche ces lignes grace a PHP.

sur IE
si je cree une ligne et ensuite je clique sur Enter, tout va bien.
Mais maintenant:
- j'ouvre mon fichier br.php dans IE
- je ne cree aucune ligne dans ma table
-je soumets mon formulaire
-j'obtiens une erreur:
'0.name' is null or not an object
-je cree une ligne
-je resoumets mon formulaire
-je n'ai plus d'erreur.
En fait je me rends compte que la premiere fois que je soumets mon formulaire, si j'ai pas cree d'objets DOM, j'ai une erreur. En effet cell2.name="brdedicated"; n'existe pas puisque je n'ai pas cree de lignes dans ma table
Sur FF
je n'ai aucune erreur.
Comment puis je faire pour ne pas avoir d'erreur avec IE?
Merci beaucoup.
Billy
