访问$ rootScope和$ scope在`$ rootScope。$ on'内

Question

我需要在URL更改时设置$ rootScope.VARIABLE。

我怎么能在$ rootScope。$回调函数中做到这一点？

$rootScope.$on('$locationChangeSuccess', function(event, absNewUrl, absOldUrl) { 
    $rootScope.alert =True; // $rootScope is undefined 
});

用你的代码withing myApp.run上下文。

myApp.run(["$rootScope", "$window", "$location",function ($rootScope, $window, $location) { 
 
\t $rootScope.$on('$locationChangeSuccess', function(evt, absNewUrl, absOldUrl) { 
 
\t \t $rootScope.actualLocation = $location.path(); 
 
\t }); 
 
\t $rootScope.$on('$locationChangeStart',function(evt, absNewUrl, absOldUrl) { 
 
\t \t $rootScope.actualLocation = $location.path(); 
 
\t }); 
 
}]);
