javascript - Calculate how many Array in the JSON -

-

i working on simple angularjs project, , have code:

this view:

<tr ng-repeat="metering in meterings">  <td>1</td>   <td>{{metering.d.serialnumber}}</td>                                          </tr>

this controller:

angular.module('mainctrl', []).controller('maincontroller', function($scope,$http,nerds) {       nerds.get()         .success(function(data){             $scope.meterings = data;         });   });

this services:

angular.module('nerdservice', []).factory('nerds', ['$http', function($http) {     return{         : function(){             return $http.get('http://amrse.net/list.json');  //let's pretend path works fine         }     }  }]);

my questions are: 1. how can number 1 in table (in view) changes dynamically? <td>1</td>

  1. i want calculate total array repeat in <td>{{metering.d.serialnumber}}</td>. like: total : {{ metering.gettotal() }}. how can that?

what metering.d (d) that's added server side added .net. if that's case use

  $scope.meterings = data.d;

then can using meterings.length find length , number can go $index+1. hope helps
