vue-router实现SPA购物APP基本功能

概述

vue-router是vue中的一个核心插件,用它来实现SPA购物APP基本功能

详细

vue-router是vue中的一个核心插件。php

1、安装

 

1.若是安装脚手架,那么能够npm install vue-router 便可安装css

而后导入而且引用就能够了。html

import VueRouter from 'vue-router'
Vue.use(VueRouter)

2.也可下载vue-router.js ,而后直接script引用也能够。vue

2、使用

用 Vue.js + vue-router 建立单页应用,是很是简单的。使用 Vue.js ,咱们已经能够经过组合组件来组成应用程序,当你要把 vue-router 添加进来,咱们须要作的是,将组件(components)映射到路由(routes),而后告诉 vue-router 在哪里渲染它们。ajax

2.1关于渲染标签vue-router

vue-router提供了两个指令标签组件来处理导航和自动渲染的逻辑vue-cli

<router-view> 渲染路径匹配到的视图组件,还能够内嵌本身的<router-view> ,根据嵌套路径渲染嵌套组件npm

<router-link> 路由中的应用导航api

2.2关于跳转app

使用router-link组件来进行导航,经过传入“to”属性指定连接

<router-link to="/home">Go to Home</router-link>

可是一样,咱们须要在js中配置路由的跳转

//定义好路由组件

//index.js  配置路由跳转
export default new Router({routes})
var routes = [
    {
      path: '/home',
      name: 'Home',
      component: Home
    }
]

2.3 关于传值

页面跳转时常常须要携带参数,因此路由跳转是能够携带参数的

//动态路径传参,以冒号开头
var routes = [
    {
      path: '/detail/:id',
      name: 'Detail',
      component: Detail
    }
]

固然在路由中也须要配置一下

<router-link :to='{name:"Detail",params:{id:x.name}}'>
    ...
</router-link>

2.4 关于参数结接收

一个『路径参数』使用冒号 : 标记。当匹配到一个路由时,参数值会被设置到 this.$route.params,能够在每一个组件内使用。因而,咱们能够更新Detail的模板,输出当前用户的商品名

<template>
    <div>
        <h1>水果详情页</h1>
        <h1>{{$route.params.id}}</h1>
    </div>    
</template>

2.5 关于渲染

默认状况下,<router-link>会被渲染成a标签输出,而有时候,为了页面的规范和美观,咱们能够将其替换成其余标签,好比<router-link to:"/home" tag="div" > 最终,<router-link>就会以div的形式显示在页面上

2.6 嵌套式路由

上文说过,路由之间是能够嵌套的,因此咱们能够在路由中进行子路由的嵌套

那么此时,首先,咱们须要先配置路由

//此时,咱们在market组件下,配置2个子路由
var routes = [
    {
      path: '/market',
      name: 'Market',
      component: Market,
      children: [
        {
          path: '/',
          component: require('../pages/market/price')
        },
        {
          path: 'price',
          component: require('../pages/market/price')
        },
        {
          path: 'rank',
          component: require('../pages/market/rank')
        }
      ]
    }
]
export default new Router({routes})

market组件中

<template>
    <div>
        <ul>
          <router-link to='/market/price' tag="li">每天特价</router-link>
          <router-link to='/market/rank' tag="li">热销榜</router-link>
        </ul>
        <router-view></router-view>
    </div>
</template>

其实这样咱们对应的子路由就配置好了。


是否是有点懵,作一个系统的例子

1.根据笔者的第一篇文章,安装下vue-cli以及学习基本知识《Vue2.0(一,vue实例)》http://www.jianshu.com/p/d5272bd2db5e

2.根据笔者的第二篇vue文章,学习一下vue的基本指令《Vue2.0(vue基本指令)》http://www.jianshu.com/p/7a8f2ce9ef5e

3.看过度割线上的内容


3、案例效果

要点

1.一级路由跳转及传参

2.子路由的配置和跳转

3.基本组件的使用和传参

麻雀虽小,可是涵盖不少知识点,基本等价于一个小的app的功能

4、案例详解

3.1 构建页面组件

创建4个主页面组件以及1个详情页组件

3.1.1home.vue

//由于点击home.vue中的任何一个商品都跳转到商品详情页,因此在渲染每个商品的时候,咱们都加上router-link,而且进行跳转的传递参数
<template>
    <div>
        <ul>
            <li v-for='x in list'>
                <router-link :to='{name:"Detail",params:{id:x.name}}'>
                    <div>
                        ![](x.img)
                    </div>
                    <h3>
                        {{x.name}}{{x.price}}
                    </h3>            
                </router-link>
            </li>
        </ul>
    </div>
</template>

<script>
    export default{
        data(){
            return {
                list:[]
            }
        },
        beforeCreate(){},
        created(){},
        computed:{},
        mounted(){
            this.$http.get('http://www.vrserver.applinzi.com/aixianfeng/apihomehot.php')
            .then(response=>{
                this.list = response.body.data;
            },response=>{

        });
        },
        methods:{},
        components:{}
    }
</script>
<style>
ul>li{
    display:block
}
</style>

3.1.2market.vue

<template>
    <div>
        <ul>
          <router-link to='/market/price' tag="li">每天特价</router-link>
          <router-link to='/market/rank' tag="li">热销榜</router-link>
          <router-link to='/market/milk' tag="li">牛奶面包</router-link>
          <router-link to='/market/fruit' tag="li">优选水果</router-link>
        </ul>
        <router-view></router-view>
    </div>
</template>

<script>
    export default{
        data(){
            return {
                list:[]
            }
        },
        computed:{},
        mounted(){},
        methods:{},
        components:{}
    }
</script>
<style>
ul,li{
        list-style: none;
    }
*{
        margin: 0;
        padding: 0;
    }
.nav{
    position: fixed;
    height: 100%;
    width:25%;
    background: #dfdfdf;
    list-style: none;
    text-align: center;
    left: 0;
    top: 0;

}
.footer{
    position: fixed;
    height: 40px;
    width:100%;
    background: #dfdfdf;
    list-style: none;
    text-align: center;
    left: 0;
    bottom: 0;
    z-index:10;
}
.nav li{
    /*width: 25%;*/
    padding: 10px;
}
.nav a{
    text-decoration: none;
}
.router-link-active{
    background:skyblue
}
.view{
    position: fixed;
    height: 100%;
    width:75%;
    background: #fff;
    list-style: none;
    text-align: center;
    right: 0;
    top: 0;
    overflow-y:auto
}
</style>

3.1.3car.vue和mine.vue简写

<template>

    <h1>个人</h1>
</template>

<script>
    export default{
        data(){
            return {
            }
        },
        computed:{},
        mounted(){

        },
        methods:{},
        components:{}
    }
</script>
<style lang='css'>

</style>

3.2组件引用和路由配置

安装好路由,而且进行组件的引入和路由的配置

import Vue from 'vue'import Router from 'vue-router'import VueResource from 'vue-resource'Vue.use(Router)
Vue.use(VueResource)import Home from 'pages/home.vue'import Market from 'pages/market.vue'import Car from 'pages/car.vue'import Mine from 'pages/mine.vue'import Detail from 'pages/detail.vue'var routes = [
    {      path: '/',      name: 'Home',      component: Home
    },
    {      path: '/home',      name: 'Home',      component: Home
    },
    {      path: '/market',      name: 'Market',      component: Market,      children: [
        {          path: '/',          component: require('../pages/market/price')
        },
        {          path: 'price',          component: require('../pages/market/price')
        },
        {          path: 'rank',          component: require('../pages/market/rank')
        },
        {          path: 'milk',          component: require('../pages/market/milk')
        },
        {          path: 'fruit',          component: require('../pages/market/fruit')
        },
      ]
    },
    {      path: '/car',      name: 'Car',      component: Car
    },
    {      path: '/mine',      name: 'Mine',      component: Mine
    },
    {      path: '/detail/:id',      name: 'Detail',      component: Detail
    }
]export default new Router({routes})

 

3.3detail.vue

点击home页中的每个商品都须要跳转到商品详情页,因此咱们要进行参数的接收和页面渲染

<template>
    <div>
        <h1>水果详情页</h1>
        <h1>{{$route.params.id}}</h1>
    </div>    
</template>

<script>
    export default{
        data(){},
        computed:{},
        mounted(){

        },
        methods:{},
        components:{}
    }
</script>
<style lang='css'>
</style>

3.4market.vue

在market组件中,咱们引用二级路由,因此须要定义router-link和router-view,由于每个二级路由须要渲染不一样的部分,好比每天特价,热销榜等等,因此咱们还须要这四个组件,看3.4

<template lang='html'>
    <div>
        <ul>
          <router-link to='/market/price' tag="li">每天特价</router-link>
          <router-link to='/market/rank' tag="li">热销榜</router-link>
          <router-link to='/market/milk' tag="li">牛奶面包</router-link>
          <router-link to='/market/fruit' tag="li">优选水果</router-link>
        </ul>
        <router-view></router-view>
    </div>
</template>

<script>
    export default{
        data(){
            return {
                list:[]
            }
        },
        computed:{},
        mounted(){},
        methods:{},
        components:{}
    }
</script>
<style lang='css'>
ul,li{
        list-style: none;
    }
*{
        margin: 0;
        padding: 0;
    }
.nav{
    position: fixed;
    height: 100%;
    width:25%;
    background: #dfdfdf;
    list-style: none;
    text-align: center;
    left: 0;
    top: 0;

}
.footer{
    position: fixed;
    height: 40px;
    width:100%;
    background: #dfdfdf;
    list-style: none;
    text-align: center;
    left: 0;
    bottom: 0;
    z-index:10;
}
.nav li{
    /*width: 25%;*/
    padding: 10px;
}
.nav a{
    text-decoration: none;
}
.router-link-active{
    background:skyblue
}
.view{
    position: fixed;
    height: 100%;
    width:75%;
    background: #fff;
    list-style: none;
    text-align: center;
    right: 0;
    top: 0;
    overflow-y:auto
}
</style>

3.5 market的四个组件

3.5.1 fruit.vue

<template>
    <List type='优选水果'></List>
</template>

<script>
import List from '../../components/List'
    export default{
        data(){
            return {
            }
        },
        computed:{},
        mounted(){

        },
        methods:{},
        components:{
            List
        }
    }
</script>
<style></style>

 

3.5.2 milk.vue

<template>
    <List type='牛奶面包'></List>
</template>

<script>
import List from '../../components/List'
    export default{
        data(){
            return {
            }
        },
        beforeCteate(){},
        create(){},
        computed:{},
        mounted(){},
        methods:{},
        components:{
            List
        }
    }
</script>
<style></style>

3.5.3price.vue

<template>
    <List type='每天特价'></List>
</template>

<script>
import List from '../../components/List'
    export default{
        data(){
            return {

            }
        },
        beforeCteate(){},
        create(){},
        computed:{},
        mounted(){},
        methods:{},
        components:{
            List
        }
    }
</script>
<style></style>

3.5.4rank.vue

<template>
    <List type='热销榜'></List>
</template>

<script>
import List from '../../components/List'
    export default{
        data(){
            return {
            }
        },
        beforeCteate(){},
        create(){},
        computed:{},
        mounted(){},
        methods:{},
        components:{
            List
        }
    }
</script>
<style></style>

仔细看着四个小组件,是否是都是一样引用了一个List.vue的组件,觉得若是这四个页面的结构是同样的,因此咱们只须要引用要给共同的组件便可

3.5.5 List.vue

<template>
<div class="mod-home">
        <ul>
            <li v-for='x in list'>
                <div class="">
                    ![](x.img)
                </div>
                <h3>
                    {{x.name}}{{x.price}}
                </h3>
            </li>
        </ul>
    </div>
</template>

<script>
export default {
  data () {
    return {
      list:[]
    }
  },
  props:['type'],
  computed:{},
  mounted(){
       var type = this.type || '每天特价';
 this.$http.get('http://www.vrserver.applinzi.com/aixianfeng/apicategory.php?category='+type)
       .then(response=>{
           this.list = response.body.data
       },response =>{

       })
  },
  methods:{}

}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
    h1, h2 {
      font-weight: normal;
    }

    ul {
      list-style-type: none;
      padding: 0;
    }

    li {
      display: block;
      margin: 0 10px;
    }

    a {
      color: #42b983;
    }
</style>

这里咱们在不一样的父组件传入一个type,在子组件List中,咱们接收type,而且根据type不一样,请求不一样的ajax便可。

6、其余补充

这样咱们一个小案例就能够正常运行了。
