How to filter JSON-Data with AngularJs?
Since your object model is kind of complex I would recommend using custom filtering function:
$scope.isActive = function(user) { return user.User.Stats[0].active === "1";};
and then in your HTML:
<div ng-repeat="user in _users | filter:isActive"> {{user.User.userid}}</div>
Here is the working jsFiddle: http://jsfiddle.net/pkozlowski_opensource/4kzzy/3/
Be sure to check angular's documentation on filters if you need more info: http://docs.angularjs.org/api/ng.filter:filter
Taking @pkozlowski.opensource a bit further and allowing live filtering of items/users:
<div ng-controller="MyCtrl"> <label>userid substring filter:</label> <input ng-model="zzzzz"> <div ng-repeat="user in _users | filter:isInteresting"> <pre>{{user | json}}</pre> </div></div>
And:
$scope.isInteresting = function (user) { if ($scope.zzzzz == undefined) { return true; } return user.userid.indexOf($scope.zzzzz) !== -1;};
