json数组angularjs中的自定义过滤器

Question

I'm new in Angularjs,i succeed to display every value from the key "type" from my json array ,but i want only to display "type" if the value is equal to "service" how can i do that. I tried to do with custom filter but i don t understand how it works. Thanks for advance for your help !

Here is my controller :

 .controller('CategorieCtrl', function ($scope, $stateParams,$state,factocategories) {

    var mytype = {};
    $scope.displaysales = function(){
        mytype = "sales";
        console.log(mytype);
    }
    $scope.displaybuys = function(){
        mytype = "buys";
        console.log(mytype);
    }
    $scope.displaycharges = function(){
        mytype = "charges";
        console.log(mytype);
    }
    $scope.displayperso = function(){
        mytype = "personals";
        console.log(mytype);
    }


    console.log(mytype);
    var mytoken = sessionStorage.getItem('token');
    factocategories.send(mytoken).then(function(conf){
        console.log(conf);
        $scope.datab = conf.data;


    })

})

here is my view :

<ion-view view-title="Catégories">
    <ion-content>
        <div class="item item-divider submenu">
<p class="submenu col-25" ng-click="displaysales()">Ventes</p><p class="submenu col-25" ng-click="displaybuys()">achats</p><p class="submenu col-25" ng-click="displaycharges()">Charges</p><p class="submenu col-25" ng-click="displayperso()">Perso</p>
        </div>
        <ul class="list" ng-repeat="item in datab track by $index">
            <li class="item" ng-model="item.type">{{item.type}}</li>
        </ul>


    </ion-content>
</ion-view>

and here is my json :

Answer 1

   <ul class="list" ng-repeat="item in datab track by $index">
            <li class="item" ng-if="item.type === 'services'">{{item.type}}</li>
        </ul>

ng-model is not required! is is meant for inputs and two data binding.

for the condinonallity use ng-if

Answer 2

Or you can use a filter like this :

<ul class="list" ng-repeat="item in datab track by $index | filter:{type:'services'}">
    <li class="item">{{item.type}}</li>
</ul>

Answer 3

use ng-if="item.type=='service'"

<ul class="list" ng-repeat="item in datab track by $index" ng-if="item.type=='service'">
            <li class="item" ng-model="item.type">{{item.type}}</li>
        </ul>
