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

问题描述

我想在检测状态变化时访问父状态的名称.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].一种可能性是使用正则表达式替换."之后的每个符号.但我想 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.

我需要补充什么?获取[parentState]?

What would I have to add? to get [parentState]?

示例:用户从状态login 到状态pets.dogs.pets 是一个抽象的父状态，dogs 是它的子状态.fromState.name 会返回 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，解决方法 toState.name.split(".")[0] 是可能的，但只能在受控条件下工作.

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

推荐答案

我觉得你可以做toState.parent.name.
