繼上一篇開發(fā)音樂播放器歌單列表頁

（1.使用router定義跳轉(zhuǎn)鏈接，2. 使用axios得到音樂第三方數(shù)據(jù)，并渲染到頁面上，3.組件之間傳值（props））

1.接下來使用了vue-router路由動(dòng)態(tài)傳值，父子嵌套式路由?

this.$router.push({
path: `/recommend/${item.id}`
});

2.router入口文件定義路由路徑：

3. 此時(shí)需要渲染路由在父組件中：

?B.使用vuex進(jìn)行狀態(tài)管理：

npm install vuex --save import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex)

定義一個(gè)state,getters,mutations，方便組件中使用：

export 導(dǎo)出vuex定義模塊

router的相關(guān)定義：

import Vue from 'vue' import Router from 'vue-router' import Helloworld from '@/components/HelloWorld' import Recommend from '@/page/recommend' import HotRecommend from '@/page/hotrecommend' import Search from '@/page/search' //引入子組件 import recommendList from '@/page/list-detail'Vue.use(Router)export default new Router({routes: [{path: '/',component: Helloworld},{path: '/recommend',component: Recommend,//子組件路由children: [{path: ':id',component: recommendList}]},{path: '/Hotrecommend',component: HotRecommend},{path: '/search',component: Search}] }) 嵌套式路由實(shí)用

vuex-- store.js設(shè)定：

import Vue from 'vue'; import Vuex from 'vuex'; Vue.use(Vuex) const state = {// count:1,songList:null } const getters = {songList:function(state) {return state.songList;} } const mutations = {/*increment(state){state.count++},decrement(state){state.count--},*/setSongList(state,item) {state.songList=item;} } const actions={/*increment: ({commit})=>{commit('increment')},decrement: ({commit})=>{commit('decrement')},*/ /* selectPlay: ({commit, state}, {list, index})=>{commit('setPlayList',list)}, */ }export default new Vuex.Store({state,mutations,getters,actions }) state，mutations,getters定義
