how can I get the length / size of a map in "ng-show"?

var map = { 
  "key1": "value1, 
  "key2": "value2, 
  "key3": "value2
}

UPDATE 01

<button ng-show="Object.keys(map).length>0"></button>

<button ng-show="_.size(angular.copy(map)>0"></button>

where and how to set the $scope.Object = Object; ??

when I set that I got the following error:

Error: [$parse:isecobj] Referencing Object in Angular expressions is disallowed! Expression: Object.keys(selectedIdeas).length>0

This isn't specific to angularjs, it's a general javascript question – ivarni Dec 05 '14 at 08:00

@vijay4vijju - it doesn't work on the ng-show. it works inside the js. – Jaxox Dec 05 '14 at 08:24
