Javascript 为什么我的Vuex模块不能工作?[vuex]未知突变类型:moduleName/突变
我已经搜索了几个小时,我不明白为什么会出现这样的错误: [vuex]未知突变类型:groceryStore/getStoreApple对groceryStore模块中所有突变的提交。 就我所知,我是照章办事的。如果您知道我在尝试访问groceryStore模块中的函数时做错了什么,请提供帮助 这是我的index.js: 位于src/store/index.js中Javascript 为什么我的Vuex模块不能工作?[vuex]未知突变类型:moduleName/突变,javascript,vue.js,vuex,vuex-modules,Javascript,Vue.js,Vuex,Vuex Modules,我已经搜索了几个小时,我不明白为什么会出现这样的错误: [vuex]未知突变类型:groceryStore/getStoreApple对groceryStore模块中所有突变的提交。 就我所知,我是照章办事的。如果您知道我在尝试访问groceryStore模块中的函数时做错了什么,请提供帮助 这是我的index.js: 位于src/store/index.js中 import Vue from "vue"; import Vuex from "vuex";

在我们交换了一些评论之后,我做了一些挖掘,发现了一个我最近构建的相当简单的Vuex模块示例。我在这里发布商店、模块和组件 您的应用程序显然要复杂得多,但我注意到,在Vuex存储中,您将模块导入编码为
import * as groceryStore from "./modules/groceries";
import userModule from './modules/user-store-module.js'
而在我的商店里,我将模块导入编码为
import * as groceryStore from "./modules/groceries";
import userModule from './modules/user-store-module.js'
我不是JavaScript模块专家,但我想我会指出这一点。以下是我的源文件:
编辑:我添加了名称空间、getter、mutations和其他组件功能来使用它们
/store/index.js
import Vue from "vue";
import Vuex from "vuex";
import * as groceryStore from "./modules/groceries";
Vue.use(Vuex);
export default new Vuex.Store({
modules: {
groceryStore: groceries,
}
});
import Vue from 'vue'
import Vuex from 'vuex'
import userModule from './modules/user-store-module.js'
Vue.use(Vuex)
export default new Vuex.Store({
modules: {
userModule: userModule
}
})
/store/modules/user-store-module.js
const userModule = {
namespaced: true,
state: () => ({
users: [
{
id: 1,
name: 'User1',
gender: 'male'
},
{
id: 2,
name: 'User2',
gender: 'female'
},
{
id: 3,
name: 'User3',
gender: 'male'
},
{
id: 4,
name: 'User4',
gender: 'female'
},
]
}),
getters: {
getMaleUsers: state => {
return state.users.filter( user => user.gender === 'male')
},
getFemaleUsers: state => {
return state.users.filter( user => user.gender === 'female')
},
},
mutations: {
addUser(state, newGender) {
let nextId = state.users.length + 1;
state.users.push({
id: nextId,
name: 'User' + nextId,
gender: newGender
})
}
}
}
export default userModule;

将为您提供文件中所有导出的对象。()
在你的情况下,它可能会给你一个对象
{
default: {}// your groceries object
}
所以请试试看
import groceryStore from "./modules/groceries";
我对Vuex很有经验,但还没有使用过模块。但是,在快速查看文档之后,您似乎缺少Vuex“modules”属性:
new Vuex.Store({modules:{a:moduleA}})
这是一个很好的观点,但恐怕它没有修复任何问题。仍然得到相同的错误:(我看到您添加了Vue.use(Vuex)
,但我看不出您是否真的在Vue实例上添加了存储(例如:在main.js
文件中,您将有新的Vue({el:“#app”,store:store})
如果您仍然有问题,我建议暂时将模块从等式中删除。只需在一个文件中构建Vuex存储区,而不使用名称空间。一旦工作正常,您可以重新添加模块/名称空间,然后查看它是否再次中断。hehe@Tim,这正是我所做的,我很震惊。当它都在中的Index.js中时在路由器文件夹旁边,它就像一个魔咒一样工作。一切看起来都很棒,只是我似乎找不到我在做什么不同…我想知道它是否与我使用Vue 2x有关?我想我可能已经发现了问题。看看你问题中的'src/store/index.js'文件,你的导入是import*,作为groceryStore从“/modules/groceries”
,但在new Vuex.Store()
中,您编写了模块:{groceryStore:groceries,}
。我认为应该是模块:{groceryStore:groceryStore,}
(不是groceries),甚至缩短为模块:{groceryStore}
。请告诉我这是否解决了问题。
