How to create filter in Angularjs?

Question

I have this collection of courses:

 [{ id: 1, courseId: 2, text: \'John\' },
  { id: 2, courseId: 2, text: \'Willi\' },
  { id: 3, courseId: 2, text: \'Inga\' },         


        

Answer 1

You could create your custom filter so that can provide you the filtered values, filter should take array of element to be filter array.

Markup

ng-repeat="course in courses| customFilter: [{"id": 3},{"id": 2},{"id": 1}]""

Filter

app.filter('customFilter', function(){
  return function(array, filterArray){
     var ids = [];
     angular.forEach(filterArray, function(val, index) {
        ids.push(val.id);
     }
     return array.filter(function(value){
        return ids.indexOf(value.id) !== -1;
     });
  }
})
