AngularJS Question

ng-switch on empty string

I'm using Angular and I want to check when a string is empty using ng-switch. The following code doesn't seem to be working for me.

<div ng-switch on="foo">
<span ng-switch-when="">This string is empty</span>
<span ng-switch-default>This string is not empty</span>

Any help with this would be appreciated.

You will need to include the empty string in your controller:

function Ctrl($scope) {
  $scope.items = ['', 'other'];
  $scope.selection = $scope.items[0];

For additional reference, see the API: http://docs.angularjs.org/api/ng.directive:ngSwitch
