角度JS控制器與JSON陣列的對象過濾器

我有以下種類的JSON，我想找到與JSON的Status : 1對象的數量，我已經嘗試了下面的方法，它不工作。角度JS控制器與JSON陣列的對象過濾器

而且我知道NG-過濾器需要僅適用於數組，但我沒有找到一個方法來做到這一點在下面的JSON數據，有人可以幫助我

預期我得到錯誤，但如何解決這個問題在我的情況

[filter:notarray] Expected array but received:

在下面的JSON數據正如你看到的我有陣列陣列，我應該得到的伯爵狀態值爲1

期望輸出

計數第一陣列的：第二陣列的1個計數：1

：第三陣列的3 計數

Angular JS Code

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

app.controller('StudentCntrl', function($scope, $http, $filter) { 
    $http.get('data.json').then(function(response) { 

    $scope.value = response.data; 

    $scope.value.forEach(function(items) { 
     $scope.eachValue = items; 
     items.forEach(function(insideItems) { 
     passvalue = $filter('filter')(insideItems, function(inputs) { 
      if (inputs.status == '1') 
      console.log(inputs.length); 
      return inputs; 
     }); 
     }); 

    }); 
    }); 
});

，你可以簡單地使用java script array filter像

arr.filter(function(a){return a.status==1}).length

或者用角

$filter('filter')(v, function(vc) {return vc.status ==1}).length

Here is working demo
