json - AngularJS filtering ng-repeat by array -

so have json data of hvac businesses , want filter them certification array using html checkbox. following code simple version of i'm working |filter , ng-model removed

angular.module("list",[])  	.controller("listcontroller",[listctrlfun])    function listctrlfun(){   this.businesses = [    {    "name": "hotcold",    "certifications": ["residential","installation"]    },{    "name": "megacorp",    "certifications": ["commercial","installation"]    }];      }

<div  ng-app="list" ng-controller="listcontroller vm">  <div>   <label>     <input type="checkbox" />  			residential   </label>    <label>      <input type="checkbox" />  			commercial   </label>    <label>      <input type="checkbox" />  			installation   </label>  </div>    <div ng-repeat="business in vm.businesses">    <p>{{business.name}}</p>  </div>  </div>

goal when checks installation both businesses show , if check commercial , install 1 show up. not sure how bind values checkboxes can crossed referenced against data. have tried this... this.types = {residential: true, commercial: true, installation: true} here , can values change when bind them checkboxes. still unsure how cross reference true/false value data

use ng-model on checkboxes, set true if checked , false if not. can pass function filter returns true if 1 of business' certification checked:

$scope.filterby = function () {   return function(e) {     return e.certifications.some(v => $scope.options[v]);   } }  $scope.options = {   installation: true,   residential: true,   commercial: true } 

with html

<div>  <label>    <input type="checkbox" ng-model="options.residential"/>             residential  </label>   <label>     <input type="checkbox" ng-model="options.commercial" />             commercial  </label>   <label>     <input type="checkbox" ng-model="options.installation"/>             installation  </label> </div>  <div ng-repeat="business in businesses | filter:filterby(business)">   <p>{{business.name}}</p> </div>
