vuex模块中的state,getters,mutations,actions调用

模块化的方法

1. 在./src目录下新建store目录新建index.js 【./src/store/index.js】,在./src/main.js中import,import store from './store'

import Vue from "vue";
import Vuex from "vuex";

import yqfk from "./yqfk";
Vue.use(Vuex);
const state = {};
const mutations = {};
const actions = {};
export default new Vuex.Store({
  state,
  mutations,
  actions,
  modules: {
    yqfk
  }
});

2. 在上述store目录下,新建yqfk.js【./src/store/yqfk.js】，导出，在index.js中导入到modules字段中

const state = {
  test:1
};
const getters = {
	testGetter(state){
		return state.test
	}
}
const mutations ={

}
const actions = {

}
export default {
  namespaced:true,
  state,
  getters,
  mutations,
  actions,
}

3. 在vue单页中使用

• state:【this.$store.state.模块名.key】
• getters:【this.$store.getters[‘模块名/key’]】
• mutations：【this.$store.commit(‘模块名/method’)】
• actions：【this.$store.dispatch(‘模块名/method’)】

<script>
export default {
  name: "Home",
  computed:{
    test(){
      return this.$store.state.yqfk.test
	},
	getTest(){
		return this.$store.geters['yqfk/testGetter']
	}
  }
};
</script>

4.mapState,mapGetters,mapMutations,mapActions 使用

<script>
import {mapState, mapGetters, mapMutations, mapActions} from 'vuex'

export default {
  name: "Home",
  computed:{
  // 两种取模块中的state值的方法
  	...mapState({
  		test:state => state.yqfk.test
  	}),
 	...mapState('yqfk',{
 		test:state => state.test
 	}), 
   ...mapGetters('yqfk',{
   		getTest: 'testGetter'
   })
  }
};
</script>
