i using angularjs filter repeat in html:

<ul ng-repeat ="name in vm.names | unique'name'> <li>{{name.name}}</li> </ul> 

here issue

c

so want count item, want display this

a num:2

b num:1

c num:2

how can that?

just use groupby filter provided angular-filter in runnable fiddle demo:

view

<div ng-controller="myctrl">   <ul ng-repeat="item in names | groupby: 'name' ">       <li>{{item[0].name}}: {{ item.length}}</li>   </ul> </div> 

angularjs application

var myapp = angular.module('myapp', ['angular.filter']);  myapp.controller('myctrl', function($scope) {   $scope.names = [{     'name': 'a'   }, {     'name': 'a'   }, {     'name': 'b'   }, {     'name': 'c'   }, {     'name': 'c'   }]; });
