\"vince_initiative\"<\/p>\n

Comme Rhonda nous l’explique r\u00e9guli\u00e8rement : \u00ab\u00a0on ne doit pas parler que de Wacom, mais aussi d’Apple avec toute son actualit\u00e9. M\u00eame si cela ne tourne pas autour de l’infographie. Ayant re\u00e7u un avis n\u00e9gatif de sa part sur un billet \u00e0 propos du nouveau maillot ext\u00e9rieur de l’\u00e9quipe foot de France, j’ai d\u00e9cid\u00e9 d’\u00e9crire sur … iOs 4.3.<\/p>\n

Aujourd’hui est donc sorti l’iOs 4.3 pour iPad, entre autre, avec un nouveau moteur Javascript.(moi, je ne parle que de l’iPad ici…)<\/p>\n

Bon, je n’avais pas voulu trop en parler lors de la pr\u00e9sentation de l’iPad 2, plus puissant et plus rapide, lors du d\u00e9bat iPad 2<\/a>. Plus que du c\u00f4t\u00e9 hardware, je soup\u00e7onnais que la r\u00e9alit\u00e9 de cette rapidit\u00e9 de l’iPad 2 provenait autant du nouveau processeur que de ce nouveau moteur Javascript. Mes soup\u00e7ons se sont confirm\u00e9s quand les 1er tests d\u00e9crivaient un iPad 2 pas si puissant que l’iPad 1 (x 1.5).<\/p>\n

Pour tous ceux qui font du d\u00e9veloppement, vous aviez du constater que les scripts Javascripts, type Jquery, ramaient pas mal sur iPad 1 avec 4.2. Et bien, avec 4.3, c’est fini. Et pour preuve, les rotators et les caroussels sont rapides et fluides, presque sans affichage des images en chargement. En plus, c’est parfait, m\u00eame quand il y a plein de caroussels ( voir pour tester : http:\/\/sorgalla.com\/projects\/jcarousel\/examples\/static_multiple.html <\/a>).
\nMais le test ultime est sur j1sk.com<\/a> o\u00f9 les 3\/4 des animations javascript ramaient totalement sur 4.2. Avec 4.3, les 3\/4 passent. Il y a toujours du ralenti, mais ce n’est rien en comparaison avec ce qui se produisait avant (chargement bloqu\u00e9, animation hach\u00e9e,…).<\/p>\n

La rapidit\u00e9 et surtout la fluidit\u00e9 des animations sont tr\u00e8s pr\u00e9gnantes sur les sites web qui, sur la colonne de droite affichent, des quantit\u00e9s de news ou de commentaires sous forme d’onglets ou de slides num\u00e9rot\u00e9s.<\/p>\n

Ce qui est int\u00e9ressant, c’est qu’en m\u00eame temps, il y a une maj de Safari qui, dans les mots, \u00a0correspond \u00e0 :<\/p>\n

– l\u2019am\u00e9lioration de la stabilit\u00e9 pour les pages web comprenant plusieurs instances d\u2019un contenu de module\u00a0;
\n– l\u2019am\u00e9lioration de la compatibilit\u00e9 avec des pages web comprenant des r\u00e9flexions d\u2019image et des effets de transition\u00a0;
\nla r\u00e9paration d\u2019un probl\u00e8me susceptible de causer l\u2019impression de pr\u00e9sentations incorrectes pour certaines pages\u00a0;<\/em><\/p>\n

\u00ab\u00a0des pages web comprenant des r\u00e9flexions d\u2019image et des effets de transition\u00a0; \u00a0\u00bb <\/em>: en langage plus compliqu\u00e9, il faut traduire par des \u00ab\u00a0pages web comprenant du jquery\u00a0\u00bb. Parce que tout ce qui est AJAX et Jquery permet de faire des effets de fluidit\u00e9, de transition, de balayage qui \u00e9taient, jadis, l’apanage de Flash uniquement. En g\u00e9n\u00e9ral, la presque totalit\u00e9 des modules Jquery sont, en fait, la traduction de modules Flash d\u00e9j\u00e0 vus en javascript. Le menu Accord\u00e9on a vraiment \u00e9t\u00e9 popularis\u00e9 par Flash, par exemple.
\nEn r\u00e9sum\u00e9, que ce soit sur Mac Os ou iOs, Apple a d\u00e9cid\u00e9 de peaufiner la gestion du javascript, cat\u00e9goris\u00e9 \u00ab\u00a0effet cool\u00a0\u00bb, sur ses navigateurs.<\/p>\n

Et mon petit doigt me dit aussi, que Flash plantera moins Safari, comme par hasard… Mais bon, parfois, mon petit doigt se trompe… Mais pas ces temps-ci…<\/p>\n","protected":false},"excerpt":{"rendered":"
