Après le view helper pour la progressbar de jQuery UI, je me suis amusé à coder un view helper pour les bouttons. Le principe reste le même, cependant j’ai ajouté un paramètre pour gérer le passage des évènements à la création du boutton.

Pour l’utiliser on place le fichier Button.php (avec le code ci-dessus) dans le dossier ZendX/JQuery/View/Helper/ et pour l’utiliser :

echo $this->button("button1", "Mon Button", array('icons' => new Zend_Json_Expr("{primary: 'ui-icon-gear'}")),
        array(), array('click'=> "function(){ alert('Hello World !'); }" ));

Enjoy !
