Bon j'ai reussi a faire un truc qui fonctionne parfaitement en local, mais lorsque le site est deployer sur IIS cela ne fonctionne plus :

"Erreur*: document.getElementById(num) is null"

Code :

//Pour creer l'ensemble de mes dic contenant mes images
 
function addElement(ht,chemin) {
    var ni = document.getElementById('vid');
    var newdiv = document.createElement('div');
    var divIdName = ht ;
    newdiv.setAttribute('id', divIdName);
    if (document.all) { newdiv.style.setAttribute("cssText", "display:none;"); }
    else {newdiv.setAttribute("style", "display:none;");}
    newdiv.innerHTML = "<img src='" + chemin + "' alt='"+chemin+"'/>";
    ni.appendChild(newdiv);
 
}
 
//pour faire disparaitre une div et faire apparaitre la suivante
function ChangeImage() {
 
if (document.getElementById) {
    document.getElementById(num).style.display = 'none';
        num = num + 1;
        document.getElementById(num).style.display = 'block';
 
    }
    if (stop != true) {
        setTimeout("ChangeImage()", 100);
    }
}

pourtant en local il trouve bien mes div, je ne comprend pas, quelqu'un aurez une idée ??

Merci d'avance, Cordialement Mozo

Est-ce que tu les vois les div dans le code html généré?

**Mozofeuk** · 10/12/2008, 09h37

Et bien non je ne les voit pas quand je fait afficher source de la page

.

En fait mes appels de la fonction addelement sont fait comme ceci (dans le aspx.cs):

IdRoute = Convert.ToInt64(Request.Params["IdRue"]);
            BDDDataContext dc = new BDDDataContext();
 
            ClientScript.RegisterStartupScript(typeof(Page), "Nblog", "<script language=javascript>nbLog=" + IdRoute.ToString() + ";</script>");
 
 
            var ListImage = (from Image in dc.Images where Image.Log_id == IdRoute select Image.Image_id).ToList();
 
            int nbimage = 1;
            foreach (long ImageId in ListImage)
            {
                string laDiv = "<div id='img" + nbimage + "' style='display:none;'><img src='logs_image/+" + IdRoute.ToString() + "/" + nbimage + ".jpg' />;";
                ClientScript.RegisterStartupScript(typeof(Page), nbimage.ToString() + "Chemin", "<script language=javascript>chemin='logs_image/" + IdRoute.ToString() + "/" + ImageId + ".jpg'</script>");
                ClientScript.RegisterStartupScript(typeof(Page), nbimage.ToString() + "nombre", "<script language=javascript>ht='"+nbimage.ToString()+"'</script>");
                ClientScript.RegisterStartupScript(typeof(Page), nbimage.ToString() + "ListImageID", "<script language=javascript>addElement(ht,chemin);</script>");
                nbimage++;
            }
            ClientScript.RegisterStartupScript(typeof(Page), "NbImage", "<script language=javascript>nbImage=" + nbimage.ToString() + ";</script>");

lorsque je fait afficher source j'obtient ceci :

on voit dans le html generé qu'il effectue bien les appels de fonction addelement avec les bons parametres mais je ne voit pas les div qu'il aurait du generé dans la fonction addelement. Pourtant (en local seulement) j'arrive bien a recuperer ces div pour les apparaitre disparaitre.

**Mozofeuk** · 10/12/2008, 14h13

Bon en fait je suis un gros boulet le probleme venez de IIS qui ne rafraichissez pas ma page aspx.cs (qui ne prennait donc pas en compte les modification que j'apportais).

J'ai quand meme était obliger de entierement redeployer le site sur IIS, car impossible de lui faire executer la nouvelle page, vider le cache du navigateur ne changeais rien autant que les pages internet temporaire stocker sur le server.

Le principal c que cela marche mtn, merci a tous
