is there way perform nested filter angular?
js
function myctrl($scope) { $scope.showall = true; $scope.checkchange = function() { for(t in $scope.categoryarray){ if($scope.categoryarray[t].on){ $scope.showall = false; return; } } $scope.showall = true; }; $scope.myfunc = function(a) { if($scope.showall) { return true; } var sel = false; for(cat in $scope.categoryarray){ var t = $scope.categoryarray[cat]; console.log(t); if(t.on){ if(a.category.indexof(t.name) == -1){ return false; }else{ sel = true; } } } return sel; }; $scope.categoryarray = [{ name: "a", on: false}, {name:"b", on: false}, {name:"c", on: false}, {name:"d", on: false}, {name:"e", on: false}, {name:"f", on: false}, {name:"g", on: false}, {name:"h", on: false}]; $scope.sessionarray = [{ "time": "9:00", "day": "day 1", "name": "session one", "category": ["a", "b", "e", "d"] }, { "time": "10:00", "day": "day 1", "name": "session two", "category": ["a", "b", "c", "d"] }, { "time": "11:00", "day": "day 1", "name": "session three", "category": ["g", "f", "d", "e"] }, { "time": "12:00", "day": "day 1", "name": "intermission a", "category": ["a", "b", "c", "d"] }, { "time": "13:00", "day": "day 1", "name": "session four", "category": ["h", "a", "e"] }, { "time": "9:00", "day": "day 2", "name": "session five", "category": ["d", "e", "b", "g"] }, { "time": "11:00", "day": "day 2", "name": "session six", "category": ["a", "e", "c"] }, { "time": "12:00", "day": "day 2", "name": "session seven", "category": ["g", "h", "b", "c"] }] html
<li ng-repeat="cat in categoryarray"> <label> <input type="checkbox" ng-model="cat.on" ng-change="checkchange()" />{{cat.name}}</label> </li> <hr> <h1><strong>category:</strong></h1> <div ng-repeat="sessionitem in sessionarray | filter:myfunc | orderby: 'id'" class="ng-scope"> <h3>{{sessionitem.name}}</h3> </div>
to nest filter add pipe | , use "filter" filter normally.
<div ng-repeat="sessionitem in sessionarray | filter:myfunc | filter:thefilter | orderby: 'id'"> check example here.
