création d'une div pour les suggestions

Bonjour à tous

J'ai un souci avec un script que j'ai récupéré.

Le script c'est un formulaire qui génère des suggestions automatiquement. Le script en lui même fonctionne très bien !

Evidemment ce formulaire je l'adapte à un site que je suis entrain de réaliser...

Mon souci: le fichier .JS génère automatiquement la <div> ou son affiché les suggestions, mon problème il est que je voudrais définir cette div a un emplacement bien déterminé et t'il possible ? (bien évidement...) mais comment ? (le JS n'est pas du tout mon fort..)

Pour moi le problème est a la fin du fichier JS je pense qu'il faut déterminer l'endroit ou la <div id="completeDiv"> </div> doit étre placer si non il me la place pas ou je désire sur la page

Merci à tous d'avance

Afin de mieux faire comprendre met attente voici une capture d'écran qui montre le problème sur l'image on s’aperçoit que le résultat s'affiche bien, mais au milieu de la page et non dans le cadre sous le formulaire.
Moi je veux qu'il soit sous le formulaire de recherche, il agrandira automatiquement la zone

Bonjour,
de ce que je viens de voir, élément qui reçoit la liste est construit de la sorte
Code:

1 2 3 4 5 function creeAutocompletionListe() { _completeListe = document.createElement("UL"); _completeListe.id = "completeDiv"; document.body.appendChild(_completeListe); }
en d'autre terme il est ajouter en fin de document.

Si tu le veux à un autre endroit tu peux soit
- mettre en dur dans la page

Code:

<ul id="completeDiv"></ul>

en prenant soin de supprimer de l'initialisation la fonction de création
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 function initAutoComplete(form, field, submit) { _documentForm = form; _inputField = field; _submitButton = submit; _inputField.autocomplete = "off"; // SUPPRIMER l'APPEL A LA FONCTION // CreeAutocompletionListe(); ////////////////////////////////// _currentInputFieldValue = _inputField.value; _oldInputFieldValue = _currentInputFieldValue; cacheResults("", new Array()) // Premier déclenchement de la fonction dans 200 millisecondes setTimeout("mainLoop()", 200) }
soit, finalement c'est la meilleure, la plus simple, solution à mon sens, donc pas de 2éme.

malheureusement sa affiche plus rien lorsque je retire CreeAutocompletionListe();

c'est gentil d'avoir essayé quand même

Navred j'ai oublié l'initialisation de la variable _completeListe, la fonction initAutoComplete devient

  _submitButton=submit;
  _inputField.autocomplete="off";
  // AJOUT
  _completeListe = document.getElementById('completeDiv');
  // SUPPRESSION
  // creeAutocompletionListe();
  _currentInputFieldValue=_inputField.value;
  _oldInputFieldValue=_currentInputFieldValue;
  cacheResults("",new Array())
  // Premier déclenchement de la fonction dans 200 millisecondes
  setTimeout("mainLoop()",200)
}

sa marche impeccable, un grand merci pour l'aide que tu ma apporté

Bon week-end
