html - How can i filter values in angularjs? -

hi how can filter values in angularjs?

• i have created plunker reference :- my plunker.

• i want filter user categories in ng-repeat question list page

user datas:-

"user": { "_id": "58072aba0f82a61823c434df", "displayname": "table 1", "dob": "2016-12-22t18:30:00.000z", "location": "chennai", "religion": "hindu", "roles": [ "admin" ], "profileimageurl": "./modules/users/client/img/profile/uploads/ac4fbab396c2f725ed5211524f171136" }, 

• categories values in array, need filter categories values in ng-repeat list page....

• for example:- if user categories values "categories": [ "religion & culture", "social psychology" ], these 2 values should filter in list of category...

my html:-

    <div ng-repeat="question in questions | filter:user.categories ">     <small>                     <span >{{$index + 1}}.</span>                       <span data-ng-bind="question.category"></span>                   </small>    </div> 

• i have used filter in ng-repeat :- | filter:user.categories

• i want filter user categories in repeat list...

• please check , update plunker know exact solution...

you need create custom filter like:

.filter('filtercategory', [  function() {   return function(questions) {    var filteredcategories = [];    if (questions && questions.length) {     angular.foreach(questions, function(question) {       console.log(question)       if(question.user && question.user.categories && question.user.categories.length){         angular.foreach(question.user.categories, function(category){           if(filteredcategories.indexof(category)<0){             filteredcategories.push(category);           }         })       }     })   }    return filteredcategories;  } }  ]) 

and in ng-repeat need write:

<div ng-repeat="category in questions| filtercategory ">
