有没有办法在两个命名空间的 vuex 模块之间分派动作?

问题描述

是否可以在命名空间模块之间分派动作?

Is it possible to dispatch an action between namespaced modules?

例如我有 vuex 模块游戏板"和通知".每个都是命名空间的.我想从游戏板向通知模块发送一个动作.

E.g. I have vuex modules "gameboard" and "notification". Each are namespaced. I would like to dispatch an action from the gameboard to the notification module.

我想我可以在调度操作名称中使用模块名称，如下所示:

I thought I could use the module name in the dispatch action name like this:

// store/modules/gameboard.js
const actions = {
    myaction ({dispatch}) {
        ...
        dispatch('notification/triggerSelfDismissingNotifcation', {...})
    }
}

// store/modules/notification.js
const actions = {
    triggerSelfDismissingNotification (context, payload) {
        ...
    }
}

但是当我尝试这样做时，我得到了一些错误，让我觉得 vuex 试图在我的游戏板模块中分派一个动作:

But when I try to do this I get errors that make me thing vuex is trying to dispatch an action within my gameboard module:

[vuex] 未知本地动作类型:notification/triggerSelfDismissingNotification，全局类型:gameboard/notification/triggerSelfDismissingNotification

有没有办法从 vuex 模块调度到模块，或者我需要在根 vuex 实例中创建某种桥接吗?

Is there a way of dispatching from vuex module to module or do I need to create some kind of a bridge in the root vuex instance?

推荐答案

你只需要指定你是从根上下文调度:

You just need to specify that you're dispatching from the root context:

// from the gameboard.js vuex module
dispatch('notification/triggerSelfDismissingNotifcation', {...}, {root:true})

现在当分派到达根时，它将拥有到通知模块的正确命名空间路径(相对于根实例).

Now when the dispatch reaches the root it will have the correct namespace path to the notifications module (relative to the root instance).

这是假设您在 vuex 商店模块上设置 namespaced: true.

This is assuming you're setting namespaced: true on your vuex store module.
