javascript - How to get child views from Backbone Marionette's composite view? - Stack Overflow

I am working on an application based on Backbone and Marionette. I am using posite view to show an table now I want to update multiple child view's together So I want their object and model. So to access them

I read this method. I tried them on posite view object but none of the method is working and throwing the error message

CheckInOutCollectionView.findByIndex is not a function

How can I access the child view object?

If you know the index of the child view:

var child = collectionView.children.findByIndex(0)

If you want to find the child view for a particular model:

var child = collectionView.children.findByModel(model)

This works because CollectionView.prototype.children is a Babysitter ChildViewContainer instance.

This works for CompositeView instances as well because CompositeView extends CollectionView.
