JavaScript, DOM et API Web HTML5

Bonjour,

j'essaye d'afficher un formulaire à la demande en cliquant sur un élément du design contenu dans un li (une icône, tout simplement). Ça fonctionne, mais j'ai plusieurs petits problèmes :

1. les icônes bougent lorsque l'on ouvre un li, il faudrait qu'elles soient fixées et que le formulaire s'ouvre en dessous.
2. je voudrais que lorsque l'on clique sur un li, le précédent se ferme et qu'il soit remplacé par le contenu du nouveau li.

J'ai mis le site là pour que vous puissez voir directement ce qui ne va pas : http://cosme.olympe.in/ci/

Ce sont mes premiers pas dans ce domaine, si vous avez des pistes ou des coups, je prendrai tout ^^ !

Merci !
Bonjour,

j'ai essayé avec le .toggle() de jquery, mais ça fonctionne si le trigger est un bouton, mais je ne suis pas arrivé à le faire marcher si c'est un <li>. Quelle est l'astuce ?
Ben j'y perds mon latin, chez moi en local ça ne fonctionne pas. Pourtant j'ai tout ce qu'il me faut (le fichier jquery est bien au même niveau que le fichier html) :

       
<html>
	<head>
        <script src="jquery.min.js"></script>

<script type="text/javascript">
$("#id_li").click(function() {
  $("p").toggle();
});
</script>

	</head>

	<body>
<ul>
<li id="id_li">Je suis une balise LI
  <p>Et moi une balise P</p>
</li>
</ul>
	</body>
</html>


Qu'est-ce que je fais mal ?
Non, la console est vide. Pas d'erreur ni d'avertissement.

J'avais déjà testé cette solution, mais voyant que ça ne fonctionnait pas quand je l'implémentais, j'avais laissé tomber...
et si tu met tes deux balises script juste avant le fin de la fermeture de la balise </body> (en tant que dernier éléments). ?
Je sais pas pourquoi je ne l'ai pas vu avant

mais le jquery c'est OBLIGATOIREMENT, et j'insiste, dans la fonction .ready();

$( document ).ready(function() {
});


c'est la base hein;
Hello,

Juste une petite précision ce n'est pas obligatoire de mettre le jQuery dans le .ready(). Mais c'est FORTEMENT conseillé. Smiley lol
Ça assure que le DOM est totalement chargé avant de le manipuler.

Car ceci fonctionnera :
<html>
	<head>
        <script src="jquery.min.js"></script>
	</head>
	<body>
<ul>
<li id="id_li">Je suis une balise LI
  <p>Et moi une balise P</p>
</li>
</ul>
<script type="text/javascript">
$("#id_li").click(function() {
  $("p").toggle();
});
</script>
	</body>
</html>
Merci de vos aides. J'ai un peu modifié tout ça pour obtenir ce que je voulais (la solution proposée fermait et ouvrait tous les li simultanément).

Désormais, mon jquery :

<script type="text/javascript">$(document).ready(function() {
    $(".toggle-trigger").click(function() {
        $(this).parent().nextAll('.toggle-wrap').first().toggle('slow');
    });
});</script>


Et un exemple html ad hoc :

<p><a class="toggle-trigger fa-envelope"><br />Écrivez-nous</a><p>
<div class="toggle-wrap" style="display:none;">
    <div class="style-single"><div class="panel">
                <p>
						<form method="post" action="#">
							<div class="field">
								<input type="text" name="name" id="name" placeholder="Identité" />
							</div>
							<div class="field">
								<input type="email" name="email" id="email" placeholder="Courriel" />
							</div>
							<div class="field">
								<textarea name="message" id="message" placeholder="Message" rows="4"></textarea>
							</div>
							<div class="field">
								<label>Êtes-vous humain ?</label>
								<input type="radio" id="robot_yes" name="robot" /><label for="robot_yes">Oui</label>
								<input type="radio" id="robot_no" name="robot" /><label for="robot_no">Non</label>
							</div>
							<ul class="actions">
								<li><a href="#" class="button">Envoyer</a></li>
							</ul>
						</form></p>
            </div></div>
</div>


Merci de m'avoir aidé !
