前端框架之Vue(10)-全家桶简单使用实例

安装

npm install vue-router --save

使用实例

vue-router初使用（webpack-simple模板）

1、切换到指定目录，执行命令（使用 vue 命令的需要安装 vue-cli ，点击查看如何安装）：

vue init webpack-simple

2、安装 vue-router ：

npm install vue-router

3、运行：

npm install
npm run dev

4、在 src 下创建名为 components 的文件夹，并在其下新建如下三个简单组件：

<template>
    <div>
        <h1>首页</h1>
    </div>
</template>
<script>
    export default{}
</script>

VMain.vue

<template>
    <div>
        <h1>列表页</h1>
    </div>
</template>
<script>
    export default{}
</script>

VList.vue

<template>
    <div>
        <h1>详细页</h1>
    </div>
</template>
<script>
    export default{}
</script>

VDetail.vue

5、修改 App.vue 文件，使用 router-link 标签：

<template>
  <div id="app">
   <ul>
      <li>
        <router-link to='/'>主页</router-link>
      </li>
      <li>
        <router-link to='/list'>列表页</router-link>
      </li>
      <li>
        <router-link to='/detail'>详细页</router-link>
      </li>
    </ul>
    <router-view/>
  </div>
</template>

<script>
export default {
  data () {
    return {
    }
  }
}
</script>

<style>

</style>

App.vue

6、配置路由：

import Vue from 'vue'
import App from './App.vue'

import VueRouter from 'vue-router'

import VMain from './components/VMain'
import VList from './components/VList'
import VDetail from './components/VDetail'

Vue.use(VueRouter);

const router = new VueRouter({
  mode: 'history',
  routes: [
    { path: '/', component: VMain },
    { path: '/list', component: VList },
    { path: '/detail', component: VDetail }
  ]
});

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

main.js

7、效果：

支持markdown语法笔记小网站实例（webpack模板）

1、初始化目录。

vue init webpack

2、安装依赖包。

"axios": "^0.18.0",
"bootstrap": "^3.3.7",
"marked": "^0.5.2",
"vue": "^2.5.2",
"vue-router": "^3.0.1",
"vuex": "^3.0.1"

3、模块编写。

<template>
  <nav class="navbar navbar-inverse">
    <div class="container-fluid">
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav">
          <li @click='select(index)' :class="{active:index==currentIndex}" v-for='(item,index) in routes'>
            <router-link :to='item.path'>{{item.title}}</router-link>
          </li>
        </ul>
      </div><!-- /.navbar-collapse -->
    </div><!-- /.container-fluid -->
  </nav>
</template>
<script>
export default {
  data() {
    return {
      currentIndex: 0,
      routes: [
        { path: '/', title: '首页' },
        { path: '/note', title: '我的笔记' },
      ]
    }
  },
  methods: {
    select(index) {
      this.currentIndex = index;
    }
  },
  created() {
    // 刷新保持超链接激活的状态
    for (var i = 0; i < this.routes.length; i++) {
      // this.$route.path 可以获取当前地址信息
      if (this.routes[i].path == this.$route.path) {
        this.currentIndex = i;
        break;
      }
    }
  }
}
</script>

4、路由配置。

import Vue from 'vue'
import Router from 'vue-router'
import Vmain from '@/components/Vmain'
import Vnote from '@/components/Vnote'

Vue.use(Router)

export default new Router({
  mode: 'history',
  routes: [{
    path: '/',
    component: Vmain
  }, {
    path: '/note',
    component: Vnote
  }]
})

/router/index.js

<template>
  <div id="app">
    <Vheader></Vheader>
    <router-view />
  </div>
</template>
<script>
import 'bootstrap/dist/css/bootstrap.min.css'
import Vheader from '@/components/Vheader'

export default {
  name: 'App',
  components: {
    Vheader
  }
}
</script>
<style>
</style>

/App.vue

5、依赖引入。

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import Vuex from 'vuex'
import axios from 'axios'
import Qs from 'qs'
Vue.config.productionTip = false;
Vue.prototype.axios = axios;
Vue.prototype.qs = Qs
Vue.use(Vuex);

const store = new Vuex.Store({
  state: {
    note: {
        id: 0,
        title: '',
        content: '',
        markedContent: ''
      },
    list:null
  },
  mutations: {
    submitNote(state) {
      let _this = this;
      let _url = 'http://127.0.0.1:8000/notes/';
      axios.request({
          url: state.note.id == 0 ? _url : `${_url}${state.note.id}/`,
          data: Qs.stringify(state.note),
          method: state.note.id == 0 ? 'post' : 'put'
        })
        .then(function(res) {
          _this.commit('showList');
        })
        .catch(function(err) {
          if (err.response) {
            console.log(err.response);
          }
        })
      console.info(state.note)
    },
    showList(state) {
      axios.get('http://127.0.0.1:8000/notes/').then(function(res) {
          store.state.list = res.data;
        })
        .catch(function(err) {
          if (err.response) {
            console.log(err.response)
          }
        })
    },
    clearData(state) {
      state.note = {
        id: 0,
        title: '',
        content: '',
        markedContent: ''
      };
    }
  }
});

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  store,
  components: { App },
  template: '<App/>',
  mounted() {
    store.commit('showList')
  }
})

/main.js
