javascript - Angular toggle filter in ng-repeat -


i'm trying display data using ng-repeat. want have filter on displayed data , when click on specific item filter should removed. when click again on specific item, filter should added again.

i've started idea, in view have:

<ion-item class="row" ng-repeat="t in tickets">     <div class="col" ng-click="togglefilter(t.name)">{{t.name}}</div> </ion-item>

in controller:

.controller('ticketctrl', function ($scope, $filter) {     $scope.togglefilter = function (name) {         name = $filter('getslice')(name);         alert(name);     } });

when alert name gives correct filtered item, it's not updating in view. think has child scope of ng-repeat, don't know how toggling filter.

does has suggestions or solution solve problem?

it's not updating in view, beacause in $scope.togglefilter modifying local variable not binded view, in list angular binded $scope.tickets variable should modify binded variable directly see changes in view, achive using $index iterator variable available when use ngrepeat https://docs.angularjs.org/api/ng/directive/ngrepeat

the result should this:

-view:

<ion-item class="row" ng-repeat="t in tickets">     <div class="col" ng-click="togglefilter(t.name, $index)">{{t.name}}</div> </ion-item>

-controller:

.controller('ticketctrl', function ($scope, $filter) {     $scope.togglefilter = function (name, index) {         $scope.tickets[index].name = $filter('getslice')(name);         alert(name);     }

ps off topic: see using ionic framework, if going use ng-repeat in mobile devices performance going better if use collection repeat directive, mobile devices doesn't perform smooth when scroll long lists of elements ng-repeat because de 2 way binding of angular. http://ionicframework.com/docs/api/directive/collectionrepeat/
