一、路由
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
body部分:
<div id="itany">
<!-- 1.-->
<router-link to='/index'>首页</router-link>
<router-link to='/detail'>详情页</router-link>
<router-link to='/about'>关于我们</router-link>
<!-- 盛放导航对应的内容-->
<router-view></router-view>
js部分:
<script src="js/vue.js"></script>
<script src="js/vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:`
<h1>这是首页</h1>
`
}
var Detail={
template:`
<h1>这是详情页</h1>
`
}
var About={
template:`
<h1>这是关于我们</h1>
`
}
// 3.配置路由
const routes=[
{path:'/',component:Index},
{path:'/index',component:Index},
{path:'/detail',component:Detail},
{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>
二、路由的嵌套
body部分:
<div id="itany">
<router-link to='/index'>首页</router-link>
<router-link to='/user'>用户页</router-link>
<router-view></router-view>
</div>
js部分:
<script src="js/vue.js"></script>
<script src="js/vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<div>
<h1>这是用户页</h1>
<ul>
<li><router-link to='/user/regist'>这是注册页面</router-link></li>
<li><router-link to='/user/login'>这是登录页面</router-link></li>
</ul>
<router-view></router-view>
</div>
`
}
var Regist={
template:`
<h3>注册页面</h3>
`
}
var Login={
template:`
<h3>登录页面</h3>
`
}
// 3.配置路由
const routes=[
{path:'/',component:Index},
{path:'/index',component:Index},
{
path:'/user',
component:User,
children:[
{path:'regist',component:Regist},
{path:'login',component:Login}
]
}
]
// 4.创建路由实例
const router=new VueRouter({
routes:routes
})
new Vue({
el:"#itany",
router:router
})
</script>
三、路由的传参
路由的传参:
查询字符串:
/user/regist?uname=jack&&upwd=123
接收:{{route.params}}
-->
body部分:
<div id="itany">
<router-link to='/index'>首页</router-link>
<router-link to='/user'>用户页</router-link>
<router-view></router-view>
</div>
js部分:
<script src="js/vue.js"></script>
<script src="js/vue-router.js"></script>
<script>
// 2.创建组件
var Index={
template:`
<h1>这是首页</h1>
`
}
var User={
template:`
<div>
<h1>这是用户页</h1>
<ul>
<li>
<router-link to='/user/regist?uname=jack&upwd=123'>这是注册页面
</router-link>
</li>
<li><router-link to='/user/login/rose/456'>这是登录页面</router-link></li>
</ul>
<router-view></router-view>
</div>
`
}
// 字符串传参 /user/regist?uname=jack&upwd=123
// 接收 {{$route.query}}
// rest传参 /user/login/rose/456
// 配置路由:{path:'login/:userName/:password',component:Login}
// 接收:{{$route.params}}
var Regist={
template:`
<div>
<h3>注册页面</h3>
<a href="#">{{$route.query}}</a>
<ul>
<li>{{$route.query.uname}}</li>
<li>{{$route.query.upwd}}</li>
</ul>
</div>
`
}
var Login={
template:`
<div>
<h3>登录页面</h3>
<a href="#">{{$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:'/user',
component:User,
children:[
{path:'regist',component:Regist},
{path:'login/:userName/:password',component:Login}
]
}
]
//4.创建路由实例
const router=new VueRouter({
routes:routes,
linkActiveClass:'active'
})
new Vue({
el:"#itany",
router:router
})
</script>
效果图:
四、vue中的ajax (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
body部分:
<div id='app'>
<!--1.-->
<router-link to='/index'>首页</router-link>
<router-link to='/detail'>详情页</router-link>
<!--盛放导航对应的内容-->
<router-view></router-view>
</div>
js部分:
<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 Index={
template:`
<h1>这是首页</h1>
`
}
var Detail={
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){//请求成功
// console.log(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:'/detail',component:Detail}
]
//4.创建一个路由实例
const router=new VueRouter({
routes:routes,
linkActiveClass:"active"
})
//5.把路由实例挂在到vue实例上
new Vue({
el:'#app',
router:router
})
</script>
json部分:
[
{
"num":1,
"pname":"apple",
"price":3,
"count":4,
"sub":12
},
{
"num":2,
"pname":"pear",
"price":4,
"count":5,
"sub":20
},
{
"num":3,
"pname":"orange",
"price":5,
"count":6,
"sub":30
}
]
