Count filtered items in ng-repeat

[Leo Nistor]

I'm trying to count and display the number of filtered items within a ng-repeat: http://jsfiddle.net/leonistor/E9prv/25/ by keeping a variable in the model ($scope).

But as soon as I try to touch it (the commented lines in the filterSearch function) an error is thrown -- "Uncaught Error: 10 $digest() iterations reached. Aborting!", and the value is wrong. I understand from previous posts that the model is "mutating" itself, and since the $count method isn't available any more I can't think of other way to accomplish my goal.

Could you offer some suggestions? (I know it's a newbie question, I'm still struggling to understand AngularJS concepts, but it's so beautiful it's worth the effort!)

Thank you!
Leo

I think you can simply look at 'length' property of the filtered array.

But it'll filter twice and may be slow...

Thanks

Doing the filtering completely in the controller using $filter service is probably the most efficient way to do this: http://jsfiddle.net/andytjoslin/E9prv/26/

Yep, doing it in the controller only once is the right way.
Even if you don't need the length property, it would be more efficient.

Have you tried:

ng-repeat="attribute in (filteredLinkAttributes = (selectedNetchandisingNode.model.attributes | filter:attributesLinkFilter))"

and then use scope.filteredLinkAttributes to calculate lenght

Hi,

Can u please send me an example on that.

My problem here is, say my object object = {"xyz":{name:"shanthi", isFemale:true}, "abc":{name:"john",isFemale:false}}

I want the count of the isFemale  false, so how i can i get that number by filtering?
