从ui路由器$ stateChangeStart获取父状态 [英] get parent state from ui-router $stateChangeStart

问题描述

检测状态更改时，我想访问父状态的名称. 到目前为止，我的代码:

I want to access the name of the parent state when detecting a statechange. My code so far:

app.run(function($rootScope, $state, authProvider) {
    $rootScope.$on("$stateChangeStart", function(event, toState, toParams, fromState, fromParams) {
        console.log(toState.name);
    });
});

返回[parentState.childState].一种可能是使用正则表达式替换."之后的每个符号.但是我猜想ui-router中必须有一个函数来获取父状态的名称.

Returns [parentState.childState]. One possibility would be to use regex to replace every symbole that comes after the "." but I guess there has to be a function in ui-router to get the name of the parent state.

我要添加什么?获得[parentState]?

示例: 用户从状态login进入状态pets.dogs. pets是抽象父状态，dogs是它的子状态. fromState.name将返回login，但我想要pets.

Example: The user comes from the state login to the state pets.dogs. pets is an abstract parent state, dogs is a child of it. fromState.name would return login but I want pets.

是的，可以采用toState.name.split(".")[0]的解决方法，但只能在受控条件下使用.

Yes, the workaround toState.name.split(".")[0] is possible but only works under controlled conditions.

推荐答案

我认为您可以做到toState.parent.name.
