路由 路由的传参 路由的嵌套 axios
路由：vue-router 带三方工具库
创建单页面应用 spa (single page application)
通过不同的URL访问不同的页面
下载：
npm install vue
npm install vue-router
1.制作一个简单的路由
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
/*
.router-link-active{
text-decoration: none;
background: orange;
color:black;
}
*/
.active{
text-decoration: none;
background: orange;
color:black;
}
</style>
</head>
<body>
<div class="itany">
<router-link to='/index'>首页</router-link>
<router-link to='/about'>详情页</router-link>
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:<h1>我是首页</h1>
}
var About={
template:<h1>我是详情页</h1>
}
// 3.配置路由
const routes=[
{path:'/',component:Index},
{path:'/index',component:Index},
{path:'/about',component:About}
]
// 4.创建一个路由实例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
// 5.把路由实例挂载到vue实例上
new Vue({
el:'.itany',
router:router
})
</script>
</body>
</html>
注释：点击之后可跳转，并出现自己所设置的样式
2.路由的传参:
查询字符串：
/user/regist?uname=jack&&upwd=123
接收：{{
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>路由的传参</title>
</head>
<body>
<div id="app">
<router-link to="/index">首页</router-link>
<router-link to="/about">用户页</router-link>
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:`
<h1>这是首页</h1>
`
}
var About={
template:`
<div>
<h1>这是用户页</h1>
<ul>
<li>
<router-link to="/about/user?uname=jack&upwd=123">注册</router-link>
</li>
<li>
<router-link to='/about/login/rose/456'>登录</router-link>
</li>
</ul>
<router-view></router-view>
</div>
`
}
var User={
template:`
<div>
<h3>我是注册页</h3>
<a href="#">{{$route.query}}</a>
<ul>
<li>{{$route.query.uname}}</li>
<li>{{$route.query.upwd}}</li>
</ul>
</div>
`
}
var Login={
template:`
<div>
<h3>我是登录页</h3>
<a href="#">{{$route.params}}</a>
<ul>
<li>{{$route.params.userName}}</li>
<li>{{$route.params.password}}</li>
</ul>
</div>
`
}
// 3、配置路由
const routes=[
{path:'/',component:Index}, {path:'/index',component:Index},
{
path:'/about',
component:About,
children:[
{path:'user',component:User},
{path:'login/:userName/:password',component:Login},
]
},
]
// 4.创建路由实例
const router=new VueRouter({
routes:routes
})
// 5.
new Vue({
el:'#app',
router:router//注册路由
})
</script>
</body>
</html>
3.路由的嵌套
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>路由的嵌套</title>
</head>
<body>
<div id="app">
<router-link to="/index">首页</router-link>
<router-link to="/about">用户页</router-link>
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:<h1>这是首页</h1>
}
var About={
template:<div> <h1>这是用户页</h1> <ul> <li> <router-link to="/about/user">注册</router-link> </li> <li> <router-link to="/about/login">登录</router-link> </li> </ul> <router-view></router-view> </div>
}
var User={
template:<h3>我是注册页</h3>
}
var Login={
template:<h3>我是登录页</h3>
}
// 3、配置路由
const routes=[
{path:'/',component:Index}, {path:'/index',component:Index},
{
path:'/about',
component:About,
children:[
{path:'user',component:User},
{path:'login',component:Login},
]
},
]
// 4.创建路由实例
const router=new VueRouter({
routes:routes
})
// 5.
new Vue({
el:'#app',
router:router//注册路由
})
</script>
</body>
</html>
4.axios
vue中的ajax 插件
下载axios:
npm install axios
1.0 vue-resource
2.0 axios
安装http-server
npm install http-server -g
使用http-server 开启一个服务器
例：
html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
/*
.router-link-active{
text-decoration: none;
background: orange;
color:black;
}
*/
.active{
text-decoration: none;
background: orange;
color:black;
}
</style>
</head>
<body>
<div class="itany">
<!-- 1.-->
<router-link to='/index'>首页</router-link>
<router-link to='/about'>详情页</router-link>
<!-- 盛放导航内容-->
<router-view></router-view>
</div>
<script src="vue.js"></script>
<script src="vue-router.js"></script>
<script src="axios.js"></script>
<script>
// 2.创建组件
var Index={
template:`
<h1>我是首页</h1>
`
}
var About={
template:`
<div>
<h1>我是详情页</h1>
<table border=1 cellspacing=0>
<thead>
<tr>
<td>编号</td>
<td>品名</td>
<td>单价</td>
<td>数量</td>
<td>小计</td>
</tr>
</thead>
<tbody>
<tr v-for="value in fruList">
<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{
fruList:null
}
},
mounted:function(){
var self=this;
axios({
method:'get',//发送数据的方式
url:'fruit.json'
}).then(function(resp){
console.log(resp.data)
self.fruList=resp.data
}).catch(function(err){//请求失败
console.log(err)
})
}
}
// 3.配置路由
const routes=[
{path:'/',component:Index},
{path:'/index',component:Index},
{path:'/about',component:About}
]
// 4.创建一个路由实例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
// 5.把路由实例挂载到vue实例上
new Vue({
el:'.itany',
router:router
})
</script>
</body>
</html>
json:
[
{
"num":1,
"pname":"apple",
"price":3,
"count":4,
"sub":12
},
{
"num":2,
"pname":"pear",
"price":4,
