Backbone.js - change not triggering while the name change

Question

In my backbone function, while the name get change the change function not at all triggering.. any one suggest me the right way to get it.. (actually i need to get changed stuff

Answer 1

I'm not sure I understand your question. What are you trying to achieve ?

I don't think that fetch accepts {add:true} as a parameter (I just checked the source code and it does not appear anywhere).

When fetch completes, it only triggers a reset event (not an add). You should listen to that if you want to do something when the content of the collection changes. You can also simplify listen to change.

Answer 2

Try removing keepUpdate from the collection and put a setTimeout in the initialize function of the view at the end. I suggest that fetch is called from the view as well as this.collection.fetch() instead of the collection's initialize function. Makes your code more reusable.

Answer 3

Collection.fetch doesn't trigger the change event. You only get the reset event. If you need more granular events, consider calling fetch with the options {update:true}.

that.fetch({update:true});

That will trigger change event for every model that was already in the collection, and add if the model was previously not in the collection.
