Question

我想将列表链接到另一个视图（轮播布局），例如carousel item no。 2。我应该把这个括号放在哪里？

                onItemDisclosure: function() {
                    [......]
                }

我想实现类似carousel.setActiveItem（x）的东西其中x是我的轮播内容。

Answer 2

onItemDisclosure: function(list, record, index) { 

//switch the view to carousel (my main content view) 
Ext.ComponentManager.get('comp').setActiveItem(1); 

//set active item for carousel according to chosen list 
Ext.ComponentManager.get('content').setActiveItem(index); 


}
