J'ai fait un tuyau de yahoo qui tire les atomes au format json; Cependant, je peux récupérer et afficher tous les éléments de ma page html à l'exception de l'attribut de l'élément.Quelqu'un pourrait-il me dire comment récupérer l'attribut media: thumb d'un flux json?
Quelqu'un pourrait-il me dire comment récupérer l'attribut media: thumb d'un flux json?
Je colle le code de la page html avec javascript. Si vous enregistrez la page html puis l'affichez dans le navigateur, vous verrez que tous les éléments nécessaires sont affichés sur la page html à l'exception du media: thumb car je ne peux pas afficher l'attribut media: thumb lorsque le flux est formaté json. Je colle également la partie du flux JSON pour que vous puissiez avoir une idée de ce dont je parle. Dites-moi comment extraire l'attribut de média: élément pouce d'un flux json en utilisant le javascript simple, mais pas de code côté serveur ni de bibliothèque javascript.
Merci.
