angularjs-scope

问题 I'm trying to figure out how AngularJS scopes work. I'm also curious why they work the way they do. I think the following behavior doesn't make sense (fiddle 1). <div ng-app="app"> <p>outer element's scope: {{$id}}</p> <custom-directive isolate-value="Hello!"> <p>inner element's scope: {{$id}}</p> <p>isolate value: {{isolateValue || 'undefined'}}</p> </custom-directive> </div> function Directive() { return { restrict: 'E', scope: { isolateValue: "@" }, link: function(scope, element,

问题 I use this code to safe work with $timeout : $scope.intervalFunction = function () { setTimeout(function () { //DO console.log('refresh'); if ($scope.currentNode) { $scope.intervalFunction(); } }, 5000) }; function setTimeout(fn, delay) { var promise = $timeout(fn, delay); var deregister = $scope.$on('$destroy', function () { $timeout.cancel(promise); }); promise.then(deregister); } $scope.intervalFunction(); it is correct? 回答1: There are a few optimizations here, if it is always the same
