角UI路由器：调用方法从控制器的OnEnter [英] Angular ui router : calling method on controller from onEnter

问题描述

我的UI一个路由器设置是这样的：

My ui router config is like this:

$stateProvider
    .state("list",{url:"/list",templateUrl:"list.html",controller:"ctrl as vm"})
    .state("list.select",
       url:'/select',
       templateUrl:'select.html',
       onEnter:function( ) { ... }
    });

该list.select国家使用相同的控制器列表中的状态。我怎么能叫从的OnEnter功能的控制器上的方法是什么？请注意，我用Ctrl键VM语法！可我也在这里访问$ stateParams？

The list.select state uses the same controller as the list state. How can I call a method on the controller from the onEnter function? Note that I'm using the "ctrl as vm" syntax! Can I also access $stateParams here?

推荐答案

您当然可以访问 $ stateParams 在的OnEnter ，以及任何其他的服务。然而，没有办法来注入电流或父（或任何其他）控制器实例

You can certainly access $stateParams in onEnter, as well as any other service. However, there's no way to inject the current or parent (or any other) controller instance.

所以，虽然你不能调用控制器上的方法，这样，你可以使用的OnEnter 或决心为preprocess东西，也许用一个标志 list.select 来检查并调用该方法。

So, while you can't invoke a method on the controller this way, you can use onEnter or resolve to preprocess something and perhaps use a flag for list.select to check and call that method.

这也可能更合理使用服务来协调此功能，但我不知道你的做法的目的，所以我需要知道更多。

It also may make more sense to use a service to coordinate this functionality, but I don't know the purposes of your approach so I'd need to know more.
