1. 理解Vue3中mapGetters的作用和用法 mapGetters的作用是简化getters的使用,通过它,你可以直接将store中的getters映射为组件的计算属性,而无需每次都通过this.$store.getters.xxx的方式访问。 2. 在Vue3项目中安装并导入Vuex 首先,你需要确保Vuex已经安装在你的Vue 3项目中。如果还没有安装,可以使用以下命令进行安装...
import { useStore, mapState, mapGetters } from "vuex"; import { getStoreMap } from './storeMap' const store = useStore(); const mappers = mapState(["token", "username"]); // const mappers = mapGetters(["getToken", "getUsername"]); //也可以获取mapGetters const mapData = getSto...
2、组件中对模块化后的store中数据的操作与使用 //组件模板中获取获取Store中user模块的getters: {{$store.getters['user/formatNickname']}} //组件 script 中获取import { useStore }from'vuex'exportdefault{ setup () {//Vue3中store类似于Vue2中this.$storeconststore =useStore() console.log(store.st...
import {mapState, mapGetters, mapMutations, mapActions} from 'vuex'
["totalPrice","currentDiscount"],"mapGetters");return{ ...storeState, ...storeGetters, }; }, }; mapState和mapGetters,module模块一起使用 复制import{ mapState, mapGetters, useStore, createNamespacedHelpers }from'vuex';import{ computed }from'vue';/** * *@param...
import { mapState,mapGetters,mapMutations,mapActions} from 'vuex' 1. 1.mapState nickname(){return this.$store.state.nickname} age(){return this.$store.state.age} gender(){return this.$store.state.gender} //一句代替上面三句 computed: mapState(['nickname','age','gender'])//映射哪些字段...
//方式一:自己直接读取this.$store.getters['personAbout/firstPersonName']//方式二:借助mapGetters读取:...mapGetters('countAbout',['bigSum']) 开启命名空间后,组件中调用dispatch //方式一:自己直接dispatchthis.$store.dispatch('personAbout/addPersonWang',person)//方式二:借助mapActions:...mapActions('...
import{computed}from'vue';import{useStore}from'vuex';constmodule='myModule';exportdefault{setup()...
官方建议我们可以使用mapGetters去解构到计算属性中，就像使用mapState一样，就可以直接使用this调用了，就...
