角ui.router，从子控制器调用父控制器的功能？ [英] Angular ui.router, call parent controller function from child controller?
问题描述
我使用的角度与ui.router并建立一个嵌套的视图。父视图有一个div其可见我可以通过父控制器上的功能切换。我想从嵌套视图的子控制器调用此函数。我会怎么做呢？
I'm using Angular with ui.router and have setup a nested view. The parent view has a div whose visibility I can toggle through a function on the parent controller. I'd like to call this function from the child controller of the nested view. How would I do this?

JS
// Code goes here
angular.module("myApp", []).controller("parent", function($scope){
$scope.parentFunction = function(){
alert("Called a function on the parent")
}
}).controller("child", function($scope){
$scope.childFunction = function(){
alert("Called a function on the child")
}
$scope.parentFromChild = function(){
alert("I know this feels weird");
$scope.parentFunction();
}
})

这是控制器继承中典型，我相信，如果你不重新定义，如果你把它叫做你从父范围相同功能范围的功能，这意味着该范围（这个问题是这样的话使得假设有关上下文的使用这种控制器虽然这是值得商榷的，如果这是真的假设你不依赖于从控制器该控制器一定的影响）的问题。
The scope on controllers is prototypically inherited I believe which means if you don't redefine a function on the scope you get the same function from the parent scope if you call it (the problem is this then makes the assumption about the context of the use of this controller though it's debatable if this is really an issue assuming you don't depend on some effect from that controller in this controller).
