对于我写的指令,如何在那里获得$scope所以我可以做$scope.$on()？我可以注入$rootScope,但我想使用$scope来捕获广播.
angular.module('monitorApp')
.run(function($rootScope,$interval) {
$interval(function(){
$rootScope.$broadcast('ONE_SEC');
},1000);
});
angular.module('monitorApp')
.directive("countDown",[ 'sseHandler',function (sseHandler) {
console.log(sseHandler.broadcastStamp.cpuResult);
return {
scope: {
countFrom: "="
},link: function(scope,$scope){
scope.countFrom = sseHandler.broadcastStamp.cpuResult;
$scope.$on('ONE_SEC',function(scope) {
sseHandler.broadcastStamp.cpuResult--;
});
}
}
}]);
更新：使用范围注入,我收到错误：
错误：[$injector：unpr]未知提供者：$scopeProvider< - $scope< - countDownDirective
angular.module('monitorApp')
.directive("countDown",'$scope',function (sseHandler,$scope) {
console.log(sseHandler.broadcastStamp.cpuResult);
return {
scope: {
countFrom: "="
},function(scope,$scope) {
sseHandler.broadcastStamp.cpuResult--;
});
}
}
}]);
解决方法
你可以使用scope.$on,你不需要尝试注入$scope：
scope.$on('ONE_SEC',function() {
//do stuff
});
