vue3中的路由与vuex

vue3中的路由

src–router–index.js

import { createRouter, createWebHashHistory } from 'vue-router'
import HomeView from '../views/HomeView'

const routes = [{
        path: '/',
        name: 'home',
        component: HomeView
    },
    {
        path: '/about',
        name: 'about',
        // route level code-splitting
        // this generates a separate chunk (about.[hash].js) for this route
        // which is lazy-loaded when the route is visited.
        component: () => import( /* webpackChunkName: "about" */ '../views/AboutView.vue')
    }
]

const router = createRouter({
    history: createWebHashHistory(),
    routes
})

export default router

main.js

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

createApp(App).use(store).use(router).mount('#app')

App.vue

<template>
  <nav>
    <router-link to="/">Home</router-link> |
    <router-link to="/about">About</router-link>
  </nav>
  <router-view/>
</template>

<style lang="less">
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}

nav {
  padding: 30px;

  a {
    font-weight: bold;
    color: #2c3e50;

    &.router-link-exact-active {
      color: #42b983;
    }
  }
}
</style>

Vuex

src–store–index.js

import { createStore } from 'vuex'

export default createStore({
  state: {
  },
  getters: {
  },
  mutations: {
  },
  actions: {
  },
  modules: {
  }
})

main.js

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'

createApp(App).use(store).use(router).mount('#app')

外部使用vuex

1.拿出store中的值
this.$store.state.num;
2.提交mutations
this.$store.commit("mutations中定义的方法","传递的数据");
3.派遣actions
this.$store.dispatch("actions中的方法","传递的参数");
