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; 
     }); 
     }); 

    }); 
    }); 
});

，你可以简单地使用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
