vuex/store使用

标签：actions   cti   outer   main   getter   创建   order   key   ice   

示例代码

main.js中添加代码

import store from "./store"    //导入store

new Vue({

  el: ‘#app‘,

  router,

  store,                                   //添加一个store

  components: {App},

  template: ‘<App/>‘

})

store文件夹中创建index.js

分为四级操作: state; mutations; action; getters

import Vue from "vue"

import VueX from "vuex"

Vue.use(VueX)

export default new VueX.Store({

  state: {

    order: {counter: 1, downmenu: 1, radios: 1, },

    totalPrice: 0,

  },

  mutations: {

    updateOrder(state, data) { //data = key , value

      if (data.counter != undefined) {state.order.counter = data.counter; }

      if (data.downmenu != undefined) {state.order.downmenu = data.downmenu; }

      if (data.radios != undefined) {state.order.radios = data.radios; }

    },

    updatePrice(state, price) {state.totalPrice = price; }

  },

  actions: {

    updateOrder(context, data) {context.commit("updateOrder", data); },

    updatePrice(context, price) {context.commit("updatePrice", price); }

  },

  getters: {

    getOrder(state) {return state.order ? state.order : {}},

    getTotalPrice(state) {return state.totalPrice >= 0 ? "￥" + state.totalPrice : 0}

  }

})

设置传值

this.$store.dispatch("updateOrder", {"counter": this.number});

获取store值

this.$store.getters.getTotalPrice;
