Vue-router2.0基础实践

想必很多人和我一样在学习vue框架,下面附Vue-router2.0

1)基础用法:

[html] view plain copy

<div id=”app”>
<h1>Hello App!</h1>
<p>
<!– 使用 router-link 组件来导航. –>
<!– 通过传入 `to` 属性指定链接. –>
<!– <router-link> 默认会被渲染成一个 `<a>` 标签 –>
<router-link to=”/foo”>Go to Foo</router-link>
<router-link to=”/bar”>Go to Bar</router-link>
</p>
<!– 路由出口 –>
<!– 路由匹配到的组件将渲染在这里 –>
<router-view></router-view>
</div>

<template id=’foo’>
<p>this is foo!</p>
</template>
<template id=’bar’>
<p>this is bar!</p>
</template>

[javascript] view plain copy

// 1. 定义(路由)组件。
// 可以从其他文件 import 进来
const Foo = { template:’#foo’ };
const Bar = { template:’#bar’ };
// 2. 定义路由
// 每个路由应该映射一个组件。 其中”component” 可以是
// 通过 Vue.extend() 创建的组件构造器,
// 或者,只是一个组件配置对象。
const routes = [
{ path: '/foo', component: Foo },
{ path: '/bar', component: Bar }
];
// 3. 创建 router 实例,然后传 `routes` 配置
// 你还可以传别的配置参数, 不过先这么简单着吧。
const router = new VueRouter({ routes:routes });
// 4. 创建和挂载根实例。
// 记得要通过 router 配置参数注入路由,
// 从而让整个应用都有路由功能
const app = new Vue({ router:router }).$mount(‘#app’);

2)动态路由匹配:

[html] view plain copy

<div id=”app”>
<h1>Hello App!</h1>
<p>
<router-link to=”/user/foo/post/123″>Go to Foo</router-link>
<router-link to=”/user/bar/post/456″>Go to Bar</router-link>
</p>
<router-view></router-view>
</div>

<template id=’user’>
<p>User:{{ $route.params.id }},Post:{{$route.params.post_id}}</p>
</template>

[javascript] view plain copy

// 1. 定义组件。
const User = {
template:’#user’,
watch:{
‘$route’(to,from){
console.log(‘从’+from.params.id+’到’+to.params.id);
}
}
};
// 2. 创建路由实例 (可设置多段路径参数)
const router = new VueRouter({
routes:[
{ path:'/user/:id/post/:post_id',component:User }
]
});
//3. 创建和挂载根实例
const app = new Vue({ router:router }).$mount(‘#app’);

3)嵌套路由:

[html] view plain copy

<div id=”app”>
<h1>Hello App!</h1>
<p>
<router-link to=”/user/foo”>Go to Foo</router-link>
<router-link to=”/user/foo/profile”>Go to profile</router-link>
<router-link to=”/user/foo/posts”>Go to posts</router-link>
</p>
<router-view></router-view>
</div>

<template id=’user’>
<div>
<h2>User:{{ $route.params.id }}</h2>
<router-view></router-view>
</div>
</template>

<template id=”userHome”>
<p>主页</p>
</template>

<template id=”userProfile”>
<p>概况</p>
</template>

<template id=”userPosts”>
<p>登录信息</p>
</template>

[javascript] view plain copy

// 1. 定义组件。
const User = {
template:’#user’
};
const UserHome = {
template:’#userHome’
};
const UserProfile = {
template:’#userProfile’
};
const UserPosts = {
template:’#userPosts’
};
// 2. 创建路由实例
const router = new VueRouter({
routes:[
{ path:'/user/:id', component:User,
children:[
// 当 /user/:id 匹配成功,
// UserHome 会被渲染在 User 的 <router-view> 中
{ path: '', component: UserHome},
// 当 /user/:id/profile 匹配成功,
// UserProfile 会被渲染在 User 的 <router-view> 中
{ path:'profile', component:UserProfile },
// 当 /user/:id/posts 匹配成功
// UserPosts 会被渲染在 User 的 <router-view> 中
{ path: 'posts', component: UserPosts }
]
}
]
});
//3. 创建和挂载根实例
const app = new Vue({ router:router }).$mount(‘#app’);

4)编程式路由:

[html] view plain copy

<div id=”app”>
<h1>Hello App!</h1>
<p>
<router-link to=”/user/foo”>Go to Foo</router-link>
</p>
<router-view></router-view>
</div>

<template id=’user’>
<h2>User:{{ $route.params.id }}</h2>
</template>

<template id=”register”>
<p>注册</p>
</template>

[javascript] view plain copy

// 1. 定义组件。
const User = {
template:’#user’
};
const Register = {
template:’#register’
};
// 2. 创建路由实例
const router = new VueRouter({
routes:[
{ path:'/user/:id', component:User },
{ path:'/register', component:Register }
]
});
//3. 创建和挂载根实例
const app = new Vue({ router:router }).$mount(‘#app’);

//4.router.push(location)
router.push({ path: ‘register’, query: { plan: ‘private’ }});

5)命名路由:
[html] view plain copy

<div id=”app”>
<h1>Named Routes</h1>
<p>Current route name: {{ $route.name }}</p>
<ul>
<li><router-link :to=”{ name: ‘home’ }”>home</router-link></li>
<li><router-link :to=”{ name: ‘foo’ }”>foo</router-link></li>
<li><router-link :to=”{ name: ‘bar’, params: { id: 123 }}”>bar</router-link></li>
</ul>
<router-view></router-view>
</div>

<template id=’home’>
<div>This is Home</div>
</template>

<template id=’foo’>
<div>This is Foo</div>
</template>

<template id=’bar’>
<div>This is Bar {{ $route.params.id }}</div>
</template>

[javascript] view plain copy

const Home = { template: ‘#home’ };
const Foo = { template: ‘#foo’ };
const Bar = { template: ‘#bar’ };

const router = new VueRouter({
routes: [
{ path: '/', name: 'home', component: Home },
{ path: '/foo', name: 'foo', component: Foo },
{ path: '/bar/:id', name: 'bar', component: Bar }
]
});

new Vue({ router:router }).$mount(‘#app’);

6)命名视图:

[html] view plain copy

<div id=”app”>
<router-link to=”/”>Go to Foo</router-link>
<router-view></router-view>
<router-view name=”a”></router-view>
<router-view name=”b”></router-view>
</div>

<template id=’foo’>
<div>This is Foo</div>
</template>

<template id=’bar’>
<div>This is Bar {{ $route.params.id }}</div>
</template>

<template id=’baz’>
<div>This is baz</div>
</template>

[javascript] view plain copy

const Foo = { template: ‘#foo’ };
const Bar = { template: ‘#bar’ };
const Baz = { template: ‘#baz’ };

const router = new VueRouter({
routes: [
{
path: '/',
components: {
default:Foo,
a:Bar,
b:Baz
}
}
]
});

new Vue({ router:router }).$mount(‘#app’);
