Filter for search result with AngularJS

Question

A quick question:

I'm creating a filter in angularjs to get dynamically a variable and to be used like this from frontend.

<div ng-if="(services | searchValue : 'type' : 'facebook').active == true">
...
</div>

This is the javascript.

.filter('searchValue', function () {
        return function (array, name_var, value) {
            angular.forEach(array, function(v, k) {
                if (v[name_var] == value) {
                    return v;
                }
            });
            return [];
        };
    })

Unfortunately even if the result was found it wasn't passed to the template.

If I'll use it like this:

{{(services | searchValue : 'type' : 'facebook')}}

This will get no value. Any suggestion?

I think it should be like (services | searchValue : 'type' ) — Naghaveer R

I've created a sample example for the info you've provided. Run the below example check. Hope this helps you.

I guess ng-if itself expects only the variable and not the expression. only provide the variable with value i.e (services | searchValue : 'type' : 'facebook').active not the expression.

var app = angular.module('application', []);

app.filter('customfilter', function() {
  return function(array, name_var, value) {
    var filteredArray = {};
    angular.forEach(array, function(v, k) {
      if (v[name_var] == value) {
        filteredArray = v;
        return false;
      }
    });
    return filteredArray;
  }

});
app.controller('sampleController', function($scope, $filter) {
  $scope.data = [{
    "type": "facebook",
    "active": false
  }, {
    "type": "linkedin",
    "active": false
  }, {
    "type": "twitter",
    "active": false
  }, {
    "type": "google",
    "active": false
  }];

  $scope.anotherdata = [{
    "type": "facebook",
    "active": true
  }, {
    "type": "linkedin",
    "active": false
  }];
});

<script data-require="[email protected]" src="https://code.angularjs.org/1.3.17/angular.js" data-semver="1.3.17"></script>

<body ng-app="application">
  <div ng-controller="sampleController">

    First div - Active : false
    <div ng-if="(data | customfilter:'type':'facebook').active">
      Your div content goes over here
    </div>
    <br>
    <br>Second div - Active : true
    <div ng-if="(anotherdata | customfilter:'type':'facebook').active">
      Second div rendered
    </div>
  </div>
</body>
