AngularJs / .provider /如何让rootScope使广播？ [英] AngularJs/ .provider / how to get the rootScope to make a broadcast?

问题描述

现在我的任务是重写$ exceptionHandler的供应商，使其输出模式对话框与消息，并停止默认事件。

Now my task is to rewrite $exceptionHandler provider so that it will output modal dialog with message and stop default event.

我做的：

在项目中的init我用的方法.provider：

in project init I use method .provider:

.provider('$exceptionHandler', function(){

//and here I would like to have rootScope to make event broadcast

})

非标准注射方法是行不通的。

standart inject method does not work.

推荐答案

您可以注入进样器和查找的$ rootScope。

You can inject the injector and lookup the $rootScope.

示范plunkr：<一href=\"http://plnkr.co/edit/0hpTkXx5WkvKN3Wn5EmY?p=$p$pview\">http://plnkr.co/edit/0hpTkXx5WkvKN3Wn5EmY?p=$p$pview

myApp.factory('$exceptionHandler',function($injector){
    return function(exception, cause){
        var rScope = $injector.get('$rootScope');
        if(rScope){
            rScope.$broadcast('exception',exception, cause);
        }
    };
})

更新：添加.provider技术太：

Update: add .provider technique too:

app.provider('$exceptionHandler', function() {
  // In the provider function, you cannot inject any
  // service or factory. This can only be done at the
  // "$get" method.

  this.$get = function($injector) {
    return function(exception,cause){
      var rScope = $injector.get('$rootScope');
      rScope.$broadcast('exception',exception, cause);  
    }
  };
});
