Je développe ce qui était auparavant un accordéon jQuery assez simple script, et j'ai fait en sorte que plusieurs accordéons puissent être placés sur la page, chacun avec son propre ID unique. Le problème est que toute interaction avec la fonctionnalité d'accordéon (développer l'un des panneaux tout en réduisant tous les autres, ou utiliser le lien développer/réduire tous) affecte TOUS les accordéons sur la page. Je ne sais pas comment faire pour que chacun d'entre eux "s'occupe de ses affaires".
En outre (et c'est un problème plus important), il est totalement incompatible avec Internet Explorer. Ce qui est vraiment étrange. Je pensais que jQuery était censé être à l'épreuve des navigateurs... ?
Bref, voici le code HTML suivi de la fonction jQuery :
<h1>accordion 1</h1>
<div class="ui-accordion">
<div class="expand"></div>
<div class="icon-24-pencilPaper"><a href="#1">panel 1a</a><span onclick="javascript:alert('hello');"></span></div>
<div class="ui-accordion-content">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque scelerisque risus mauris. Nullam lorem eros, sollicitudin ut rutrum in, sollicitudin tristique nisi. Mauris euismod dui amet.
</div>
<div class="icon-24-binoculars"><a href="#2">panel 2a</a><span onclick="javascript:alert('hello');"></span></div>
<div class="ui-accordion-content">
Nullam laoreet imperdiet felis et faucibus. Aenean vitae iaculis mauris. Quisque semper semper nunc, eu cursus tortor sagittis eget. Etiam vel condimentum velit. Vivamus mollis laoreet amet.

<div class="icon-24-person"><a href="#3">panel 3a</a><span onclick="javascript:alert('hello');"></span></div>
