i trying group nodegroup using underscore library

vm.populatednodegroups = _($scope.nodes).groupby(function (o) {                  return o.nodegroup.name;             }); 

in vm.populatednodegroups 2 keys (are 1 routers , 2 switches) 2 arrays each.

what trying 2 node group objects 2 arrays each.

any suggestions?

there a working example

i say, there. our view, consuming underscore groupby:

<div ng-controller="thectrl">    <div ng-repeat="(key, values) in populatednodegroups">     <h3>{{key}}</h3>     <ul>        <li ng-repeat="value in values">{{value | json}}</li>     </ul>   </div> </div> 

here our controller, doing groupby

app.controller('thectrl', ['$scope', function ($scope) {               var result = _(data)       .groupby(function (o) {          return o.nodegroup.name;       })       ;      $scope.populatednodegroups = result;  }]) 

the result

area 2 switches

• { "nodegroup": { "name": "area 2 switches" ... } ... }
• { "nodegroup": { "name": "area 2 switches" ... } ... }

areaa 1 routers

• { "nodegroup": { "name": "areaa 1 routers" ... } ... }
• { "nodegroup": { "name": "areaa 1 routers" ... } ... }
