J'utilise du javascript et lors de l'esai de validation voici la seule erreur :

Citation : W3C xHTML 1.0

Error Line 134 column 13: there is no attribute "onClick".

<a onClick="return supprimer('administration/liste_news-17-delete.html')" styl

You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute.

Citation : W3C recommandation

XHTML documents must use lower case for all HTML element and attribute names. This difference is necessary because XML is case-sensitive e.g. <li> and <LI> are different tags.

Hep !

Alors, je te le dis tout de suite, je connais pas, mais alors, paaaas du tout le Javascript, mais essaie donc de mettre un "c" minuscule !

Désolé si c'est pas ça !

This Page Is Valid XHTML 1.0 Strict!

Faudrait que tu lises les recommandations du w3c un de ces jours...
