AngularJS - ngShow - does it perform the DOM composition? -


i know if ngshow evaluates false, still performs dirty checking inside directive.

so ngshow (like ng-show=false):

  • compose dom inside ngshow (since has $compile) , hides/removes contents, or
  • only performs dirty checking without cost of creating dom elements?

ng-show set elements display: none. still in dom , still dirty checked angular.

try using ng-switch removing elements dom. http://docs.angularjs.org/api/ng.directive:ngswitch
