View Full Version : Getting card indexes on Container.onActiveItemChange()

31 Jan 2012, 2:28 PM
After a lot of experimenting I got it to work but not confident this is the best way to do it. What I want to do is when navigating back remove the old card on my NavigationView (I'm not using the built in Back button). Here is what I came up with but wondering if there is a better/safer way?

onActiveItemChange: function(container, value, oldValue, opts) {
var me = this,
newIdx = Ext.Array.indexOf(value.parent.getInnerItems(), value),
oldIdx = Ext.Array.indexOf(value.parent.getInnerItems(), oldValue);

if (newIdx < oldIdx) {

Should be just fine.
