To handle the reload itself (which includes hitting F5) and to take action before it reloads or even cancel, use 'beforeunload' event.
要处理重新加载本身（包括按 F5）并在重新加载甚至取消之前采取行动，请使用 'beforeunload' 事件。
var windowElement = angular.element($window);
windowElement.on('beforeunload', function (event) {
//Do Something
//After this will prevent reload or navigating away.
event.preventDefault();
});

You can use $routeChageStart:
您可以使用$routeChageStart：
$rootScope.$on('$routeChangeStart', function () {
alert('refresh');
});
