javascript - ng-show not working on returned function value? -


the logic simple. show link when there @ least 1 checkbox checked. within calculate checkbox function.

js

  $scope.calculatechecked = function() {       var count = 0;       angular.foreach($scope.data, function(value) {         if(value.checked)           count++;       });           if(count !=0){             return count;         }else{             return "null";         }    };

html

 <a ng-show="{calculatechecked()}!='null'" ng-click="getlinks()"><p ng-show="loader==false" class="newtopic">open {{calculatechecked()}} topic</p></a>

i expect work ng-show="{calculatechecked()}!='null'"but doesn't

remove braces in ng-show

<a ng-show="calculatechecked() != 'null'" ng-click="getlinks()"><p ng-show="loader==false" class="newtopic">open {{calculatechecked()}} topic</p></a>
