Je sais que ça peut être facile mais je n'y connais pas beaucoup en programmation.

Merci

Bonjour,

Ne pourrais-tu pas simplifier le code que tu répètes plusieurs fois en le remplaçant par quelque chose comme ça ?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
numImage = Math.floor(Math.random() * nbImages);
document.write("<img src='images/img-0"+numImage+".jpg' border='0'>");

avec nbImages précédemment déclarée

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

var nbImages=36;

Bonjour,
heu .... elle est vide, ta fonction image()

(regarde les accolades).

Place ton code (celui qui suit la première fois) à l'intérieur des accolades de la fonction, puis place la fonction dans le <head>.
Tu n'auras plus qu'à appeler image(); à chaque fois que tu en as besoin ...

Et tu devrais changer le nom : image est un terme du langage. Il ne faut donc pas le réutiliser sous peine de confusion du nav (donc bugs potentiels).

EDIT : @micetf > Non !! Pas de document.write()

Certes,
mais il me semble que dans le code javascript que eiffel74 ne veut pas répéter plusieurs fois, c'est finalement ce qu'il souhaite faire :

function image()
{
	var nbImages=36; 
	numImage = Math.floor(Math.random() * nbImages);
	document.write("<img src='images/img-0"+numImage+".jpg' border='0'>");
}

Mais effectivement,
ensuite on peut basculer sur cette discussion :
document.write() et innerHTML interdit ?

C'est vrai : je n'avais pas regardé assez en détail

Discuter, oui on peut

Mais on peut aussi utiliser directement la méthode la plus correcte

(EDIT : ce qui n'empêche pas, tu l'auras noté, de prendre en compte ton optimisation

)

document.write() étant proscrit,
voilà comment personnellement j'aurais codé tout ça :

mais ce n'est pas forcément la méthode la plus correcte... prudence !

Tout bien réfléchi,
je n'aurais pas utilisé javascript,
j'aurais laissé le travail au serveur avec une touche de PHP :

Mais là, il va falloir changer de forum.

Merci pour ces réponse...en fait j'ai décidé d'utiliser le php et ça marche.
