Iterate over Carousel Items

Items in Carousel is of type Ext.util.MixedCollection, NOT an array although you can initialize it with an array.

Say,
c = new Ext.Carousel({
    id: 'myCarousel'
    items:[ {...}, {...} ]
});

to iterate:
var noOfItem = Ext.getCmp('myCarousel').items.length;
for(i=0;i<noofitem;i++){
   Ext.getCmp('myCarousel').items.get(i);
}
