pour commencer, je serais étonné que ça marche avec mozilla (event) et pour finir, expliques pluotto ce que tu veux faire avec ce scritp... En js, on a souvent 2, 3 ou 4 façon d'arriver au même endroit alors expliqie ce quetu veux faire, on poura peut-être passer par un chemin plus portable...
les vars au début ne sercvent a rien.
