vuex 获取数据

npm i vuex --save

2: store文件夹下 index.js

import Vue from 'vue'

import Vuex from 'vuex'

Vue.use(Vuex)

export const store = new Vuex.Store({

state: {

login: 'login',

test: 'test'

}

})

3: main.js

import Vue from 'vue'

import Vuex from 'vuex'

import App from './App'

import {store} from './store'

Vue.use(Vuex)

new Vue({

el: '#app',

router,

store,

components: { App },

template: '<App/>'

})

 

 

获取vuex中的数据一般写在computed(计算）中

import {mapState, mapGetters, mapMutations} from 'vuex'

export default {

data () {

return {

}

},

computed: {

...mapState(['user']),

...mapGetters(['person'])

},

methods: {

// ...mapMutations(['setUser']), //调用mutations中方法的第一种方式

submitUserNameForm () {

// this.setUser('456')

this.$store.commit('setUser','456') //调用mutations中方法的第二种方式

}

}

}
