[AJAX] [Scriptaculous] redimensionner dynamiquement div

Bonjour,

Je cherche a donner a l'utilisateur la possibilité de redimensionner en ligne un div.

En gros, je voudrais avoir le meme principe que celui qui s'applique aux images:
Quand on passe la souris sur le coin ou sur un côté du div, l'icone de redimension apparait, et permet la redimension du div en déplacant la souris...

J'ai compris le principe :
Il faut savoir a quelles coordonnées on est quand on clique, puis en faisant la différence avec les coordonnées quand on lache la souris on sait le deplacement effectué, puis on met a jour la balise style="width:; height:;" en fonction de ce déplacement...

Mais en pratique, je ne vois pas du tout comment m'y prendre!!

Merci d'avance pour vos réponses

oulaaa c'est beaucoup de chose.

Je sais meme pas par ou commencer :) On va tenter :P
Alors en premier lieu utilise onmousedown, onmousemove et onmouseup sur la window(global) en y associant une fonction (regarde addEventListener (firefox) et attachEvent(ie)).
Puis sur la fonction down tu recuperes l'objet fraichement selectionné (avec les evenements et target).
Puis apres c'est un travail assez complexe. Tout d'abord recuperer la position de la sourie puis de l'objet en cour (avec offset en javascript tu recuperes tout) et la tu fais tes calculs. Puis lors du onmousemove tu sets les valeurs de la sourie sur le div associé au coin voulu. Lors du on mouseup tu effaces toutes les valeurs globals eventuels :)
Pour que ton objet en cour soi accessible partout met le en global. J'espere que tu as deja fais du js car ca va te demander pas mal de fil a retordre mais si tu le fais c'est la classe :) :king: :king: :king: :king:
Voila tiens moi au courant si tu as d'autre question ;)

n'y a t'il pas quelque choses du coté de scriptaculous ?? :roll:

Moi je suis un peu foufou je le recode moi meme :yaisse2: Apres script aculous c'est un truc genial ! mais bon :lol: On est sur developpez.com :roll:

Je viens de regarder du coté de scriptaculous, mais il n'y a que des scripts de deplacement et pas de redimensionnement...

Franchement essait de le coder :) et puis je peux tenter de t'aider. Le desavantage de le coder soi meme c'est que c'est plutot long, la compatibilité entre navigateurs fait chier mais tu vas en sortir avec une excellente connaissance :)
:king:

J'ai trouvé ceci, mais je n'arrive pas à comprendre tout car je n'ai jamais utilisé les classes en javascript...
Comment je peux utiliser ceci pour me permettre de resizer mon div (comment faire appel à la fonction?...)

meme en ayant aucune idée de la fonctionnalité de cette source il manque les choses indispensables de la gestion de la sourie et des evenements associés a la sourie. Ce code n'est que la fin de ce que tu souhaites faire. Un conseil oriente toi d'abord sur la gestion des evenements (pourquoi pas drag and drop, c'est la meme mthode) et apres tu t'orienteras sur ce code. Mais honnetement apres cette pris la tete avec le drag and drop tu feras le code que tu a montrer tout seul :) si si je t'assure :roll:

Parce que le truc c'est que je pense ne pas maitriser suffisament le js pour faire ca...

Voici le code qui crée un window où l'on peut mettre l'option resizable...

J'aimerais bien pouvoir isoler la fonction de resize de ce code, car, si le contenu est plus gros que le div, il crée automatiquement un scroll pour faire défilé le contenu...

Voici le code:

ouaaa la tartine :| en effet meme moi la je suis paumé dans un truc pareille :S
La je suis paumé. Je crois qu'il va falloir que tu chauffes une tasse a café et que tu te farcisses un bon tuto js :mouarf:

Je crois avoir trouvé un trux pas mal, plus a ma portée!!

EN fait ce code fait le resize et le deplacement du div...
Donc je voudrais réutiliser le code en enlevant la capacité de déplacement du div...

Mais bon, il y a des lignes que je ne comprend pas :oops: :lol:

j'ai testé le script mais il est pas geniale geniale. Toi ce que tu veux faire c'est un resize du div sans le drag and drop ? juste redefinir a la sourie la taille en tirant un bord? Car si c'est ca je peux essayer de t'expliquer la demarche a suivre ;)

Oui c'est ca, je souahiterais utiliser le script au dessus en enlevant la partie drag and drop pour n'utiliser que la partie resize avec les bords du div...

Mais j'aurai besoin d'un coup de main, car je ne comprend pas tout de ce script...:oops:

poster par tober, il est fonctionnel :) seulement quelque petit hic mais regarde le il vaut le coup d'oeil :mouarf:
