Placer une vidéo à la place d'une image

**mrangers** · 28/03/2013, 11h37

Bonjour,

Je suis en train de créer mon site en m'inspirant d'un template avec toutes les sources.
Dans la partie multimédia je n'arrive pas à remplacer les fichiers images par des vidéos. j'ai tout essayé (afin, je crois), dans le hode html mais rien n'y fait. il me semble alors que ça doit se jouer dans le code jquery que voici ci-dessous:

Code :

Que dois-je faire pour lui indiquer que je souhaite lire des fichiers vidéos à la place des images.

Voici si nécessaire une portion du code html concerné :

Code html :

Sélectionner tout - Visualiser dans une fenêtre à part

1

<a href="#" data-largesrc="images/2.jpg" data-title="#" data-description="#"> 
<img src="images/thumbs/2.jpg" alt="img02"/></a>

Merci d'avance pour votre aide

Cordialement,

Will

Bonsoir

Pour une vidéo ce n'est pas le tag "img" mais le tag "video" en HTML5.

Exemple :

Code html :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
<video controls>
  <source src="foo.ogg" type="video/ogg">
  <source src="foo.mp4" type="video/mp4">
  Your browser does not support the <code>video</code> element.
</video>

Bonjour,

Merci pour votre réponse.
J'ai mis le code que vous m'avez fourni, mais je n'obtiens pas l'effet souhaité !
Il me semble que c'est après ce tag que je dois mettre le lien de la vidéo qui remplacerait l'image : data-largesrc="images/1.jpg". Mais quelle balise/tag utiliser ? Y a-t-il une mise à jour à faire au niveau du code JavaScript ?

Cordialement,

Will
