今天学习了路由的传参和axios
路由的传参
1.查询字符串：
/user/regist?uname=jack&upwd=123
接收：
{{$route.query}}
2.rest风格传参
/user/login/rose/456
<body>
<div id='app'>
<router-link to='/home'>首页</router-link>
<router-link to='/user'>用户页</router-link>
<router-view></router-view>
</div>
<script src='js/vue.js'></script>
<script src='js/vue-router.js'></script>
<script>
//2
var Home={
template:`
<div>我是首页</div>
`
}
var User={
template:`
<div>
我是用户页
<p>
<router-link to='/user/regist?uname=jack&upwd=123'>注册</router-link>
</p>
<p>
<router-link to='/user/login/rose/456'>登录</router-link>
</p>
<router-view></router-view>
</div>
`
}
var Regist={
template:`
<div>
<h1>这是注册页面</h1>
<a href="">{{$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>
</body>
axios
axios:vue中的Ajax
用git安装axios
$ npm install axios
下载一个http-server
$ npm install axios http-server -g
用git申请一个http-server充当服务器
$http-server
写一个json文件
<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>
json文件
[
{
"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
}
]
写的东西必须在申请的服务器中打开
