[英]How to stop $interval on leaving ui-state?
Angular, UI-router. Angular,UI路由器。 Using $interval in a controller of a state like so:
在如下状态的控制器中使用$ interval:
$scope.Timer = null;
$scope.startTimer = function () {
$scope.Timer = $interval($scope.Foo, 30000);
};
$scope.stopTimer = function () {
if (angular.isDefined($scope.Timer)) {
$interval.cancel($scope.Timer);
}
};
The problem? 问题? The timer persists upon leaving the state.
计时器在离开状态时仍然存在。 My understanding was that the $scope and the controller are essentially "destroyed" when a state is left.
我的理解是,当一个州离开时,$ scope和控制器基本上被“摧毁”了。 So, based on that, the timer should stop (Within the controller, I am cancelling the timer when moving around, that works - but it persists if I navigate to a diff state).
因此,基于此,计时器应该停止(在控制器内,我在移动时取消计时器,这是有效的 - 但如果我导航到差异状态它会持续存在)。 What am I misunderstanding here?
我在这里误解了什么?
I guess since interval and timeout are services in angular, they are available everywhere, but I still don't understand how they see functions in the not-initialized controller, unless it's copied. 我猜因为间隔和超时是有角度的服务 ,它们随处可用,但我仍然不明白他们如何在未初始化的控制器中看到函数,除非它被复制。 Is my solution to just use regular good-old js interval?
我的解决方案只是使用常规的良好的旧js间隔?
