1.路由的传参

下载：
npm install vue-router
路由的传参：
1.查询字符串：
/user/regist?uname=jack&upwd=123
接收：
{{$route.query}}

<body>
 <div id='app'>
   <router-link to='/home'>首页</router-link>
   <router-link to='/user'>用户页</router-link>
   <router-view></router-view>
 </div>
<script src='js/vue.js'></script>
<script src='js/vue-router.js'></script>
<script>
   //2
    var Home={
        template:`
         <div>我是首页</div>
        `
    }
     var User={
        template:`
         <div>

              我是用户页
             <p>
                <router-link to='/user/regist?uname=jack&upwd=123'>注册</router-link>
              </p>
             <p>
                <router-link to='/user/login/rose/456'>登录</router-link>
              </p>
               <router-view></router-view>
         </div>
        `
    }
    var Regist={
        template:`
           <div>
           <h1>这是注册页面</h1>
           <a href="">{{$route.query}}</a>
           <a href="">uname:{{$route.query.uname}}</a>
           <a href="">upwd:{{$route.query.upwd}}</a>
          </div>
         `
    } 
     var Login={
        template:`
             <div>
               <h1>这是登录页面</h1>
               <a>{{$route.params}}</a>
               <a>{{$route.params.uname}}</a>
               <a>{{$route.params.upwd}}</a>
             </div>
            `
    }  
  //3.
     const routes=[
         {path:'/',component:Home},
         {path:'/home',component:Home},
         {
             path:'/user',
             component:User,
             children:[
                 {path:'regist',component:Regist},
                 {path:'login/:uname/:upwd',component:Login}
             ]
         }
     ]
   //4.创建实例
     const router=new VueRouter({
         routes:routes
     })
     
     
  new Vue({
      el:"#app",
      router:router
  })
</script>

2.vue中的ajax (axios) 前端和后台交互

vue中的ajax 插件
下载axios:
npm install axios
1.0 vue-resource
2.0 axios

例：html部分

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>
/*
    .router-link-active{
        color:red;
    } 
*/
    .active{
        color:red;
    }
</style>
</head>
<body>
 <a></a>
<div id='app'>
 <!--1.-->
 <router-link to='/home'>首页</router-link>
 <router-link to='/user'>用户页</router-link> 
 
<!-- 盛放链接对应的内容-->
  <router-view></router-view>
  </div>
 <script src='js/vue.js'></script> 
 <script src='js/vue-router.js'></script>
 <script src='js/axios.js'></script>
 <script>
   //2.创建组件
   var Home={
       template:`
         <h1>这是首页</h1>
       `
   }
   
   var User={
       template:`
         <div>
            <h1>这是用户页</h1>
             <table border=1 cellspacing=0>
               <thead>
                   <tr>
                     <th>编号</th>
                     <th>品名</th>
                     <th>单价</th>
                     <th>数量</th>
                     <th>小计</th>
                   </tr>
               </thead>
               <tbody>
                  <tr v-for="value in list">
                     <td>{{value.num}}</td>
                     <td>{{value.pname}}</td>
                     <td>{{value.price}}</td>
                     <td>{{value.count}}</td>
                     <td>{{value.sub}}</td>
                  </tr>
               </tbody>
             </table>
         </div>
        `,
       data:function(){
           return{
              list:null
           }
       },
       mounted:function(){
           var self=this;
           axios({
               method:"get",//get post
               url:'fruit.json'
           }).then(function(resp){//请求成功
               console.log(resp.data)
               self.list=resp.data;
           }).catch(function(err){//请求失败
               console.log(err)
           })
       }
       
   }
   
   //3.配置路由
   const  routes=[
       {path:'/',component:Home},
       {path:'/home',component:Home},
       {path:'/user',component:User}
   ]
   
   //4.创建路由实例
   const router=new VueRouter({
       routes:routes,
       linkActiveClass:'active'
   })
   
   //5.路由实例挂载到vue实例上
   new Vue({
       el:'#app',
       router:router
   })   
</script>
</body>
</html>

json部分：

[
    {
      "num":1,
      "pname":"apple",
      "price":3,
      "count":2,
      "sub":6
  },
  {
      "num":2,
      "pname":"pear",
      "price":4,
      "count":3,
      "sub":12
  },
  {
      "num":3,
      "pname":"banana",
      "price":5,
      "count":4,
      "sub":20
  }
]
