本文主要和大家介绍vue router 动态路由和嵌套路由,详细的介绍了动态路由和嵌套路由的使用方法,有兴趣的可以了解一下,希望能帮助到大家。

首先介绍一下动态路由。
动态路由按照我的理解,就是说能够进行页面的跳转,比如说:下面的这个页面中:


<template> 
 <p id="app"> 
  <header> 
   <router-link to="/">/</router-link> 
   <router-link to="/hello">/hello</router-link> 
   <router-link to="/cc">/cc</router-link> 
  </header> 
  <router-view style="border: 1px solid red"></router-view> 
 </p> 
</template>

如果点击了/hello,那么在router-view中就会加载对应的模块,也就是在路由中设置的模块。


import Vue from &#39;vue&#39; 
import Router from &#39;vue-router&#39; 
import Hello from &#39;@/components/Hello&#39; 
import Foo from &#39;@/components/Foo&#39; 
import Foo2 from &#39;@/components/Foo2&#39; 
import Foo3 from &#39;@/components/Foo3&#39; 
 
Vue.use(Router) 
 
export default new Router({ 
 routes: [ 
  {path: &#39;/&#39;, redirect: &#39;/hello&#39;}, 
  { 
   path: &#39;/hello&#39;, 
   component: Hello, 
   children: [ 
    {path: &#39;/hello/foo&#39;, component: Foo}, 
    {path: &#39;/hello/foo2&#39;, component: Foo2}, 
    {path: &#39;/hello/foo3&#39;, component: Foo3} 
   ] 
  }, 
  { 
   path: &#39;/cc&#39;, 
   name: &#39;Foo&#39;, 
   component: Foo 
  } 
 ] 
})

也就是说,会跳转到Hello和Foo这两个组件。

那么嵌套路由是什么意思呢,最开始我以为的是这样:/hello/foo 和/hello/foo2这两个路由可以简写成嵌套路由,其实不是的。嵌套路由只的是,在子组件中再次嵌套组件。然后在使用路由进行跳转,这样跳转的时候,变化的就只有子组件,而外边的父组件没有变化。

下面我把完整的例子放出来,看一下:

App.vue


<template> 
 <p id="app"> 
  <header> 
   <router-link to="/">/</router-link> 
   <router-link to="/hello">/hello</router-link> 
   <router-link to="/cc">/cc</router-link> 
  </header> 
  <router-view style="border: 1px solid red"></router-view> 
 </p> 
</template> 
 
<script> 
export default { 
 name: &#39;app&#39; 
} 
</script> 
 

Foo.vue


<template> 
 <p> 
  <h1>3434234343</h1> 
 </p> 
</template> 
 
<script> 
 export default { 
  name: &#39;Foo&#39;, 
  data () { 
   return { 
   } 
  } 
 } 
</script> 
 
<!-- Add "scoped" attribute to limit CSS to this component only --> 
<style scoped> 
 h1, h2 { 
  font-weight: normal; 
 } 
 
 ul { 
  list-style-type: none; 
  padding: 0; 
 } 
 
 li { 
  display: inline-block; 
  margin: 0 10px; 
 } 
 
 a { 
  color: #42b983; 
 } 
</style>

Foo2.vue


<template> 
 <p> 
  <h1>this is Foo2</h1> 
 </p> 
</template> 
 
<script> 
 export default { 
  name: &#39;Foo2&#39;, 
  data () { 
   return { 
   } 
  } 
 } 
</script> 
 
<!-- Add "scoped" attribute to limit CSS to this component only --> 
<style scoped> 
 h1, h2 { 
  font-weight: normal; 
 } 
 
 ul { 
  list-style-type: none; 
  padding: 0; 
 } 
 
 li { 
  display: inline-block; 
  margin: 0 10px; 
 } 
 
 a { 
  color: #42b983; 
 } 
</style>

Foo3.vue


<template> 
 <p> 
  <h1>this is foo3</h1> 
 </p> 
</template> 
 
<script> 
 export default { 
  name: &#39;Foo3&#39;, 
  data () { 
   return { 
   } 
  } 
 } 
</script> 
 
<!-- Add "scoped" attribute to limit CSS to this component only --> 
<style scoped> 
 h1, h2 { 
  font-weight: normal; 
 } 
 
 ul { 
  list-style-type: none; 
  padding: 0; 
 } 
 
 li { 
  display: inline-block; 
  margin: 0 10px; 
 } 
 
 a { 
  color: #42b983; 
 } 
</style>

Hello.vue


<template> 
 <p class="hello"> 
  <h1>{{ msg }}</h1>

  <router-view style="border: solid 1px blue"></router-view>

</template> 
<script> 
 export default {

  data () { 
   return { 
    msg: &#39;Welcome to Your Vue.js App&#39; 
   } 
  } 
 } 
</script> 
 
<!-- Add "scoped" attribute to limit CSS to this component only --> 
<style scoped> 
 h1, h2 { 
  font-weight: normal; 
 } 
 
 ul { 
  list-style-type: none;

 } 
 
 li { 
  display: inline-block; 
  margin: 0 10px; 
 } 
 
 a { 
  color: #42b983; 
 } 
</style>

路由:


import Vue from &#39;vue&#39; 
import Router from &#39;vue-router&#39; 
import Hello from &#39;@/components/Hello&#39; 
import Foo from &#39;@/components/Foo&#39; 
import Foo2 from &#39;@/components/Foo2&#39; 
import Foo3 from &#39;@/components/Foo3&#39; 
 
Vue.use(Router) 
 
export default new Router({ 
 routes: [ 
  {path: &#39;/&#39;, redirect: &#39;/hello&#39;}, 
  { 
   path: &#39;/hello&#39;, 
   component: Hello, 
   children: [ 
    {path: &#39;/hello/foo&#39;, component: Foo}, 
    {path: &#39;/hello/foo2&#39;, component: Foo2}, 
    {path: &#39;/hello/foo3&#39;, component: Foo3} 
   ] 
  }, 
  { 
   path: &#39;/cc&#39;, 
   name: &#39;Foo&#39;, 
   component: Foo 
  } 
 ] 
})

需要注意的是仔细的看App.vue和Hello.vue中,都包含975b587bf85a482ea10b0a28848e78a4dd6e4ababe59793a4ac75fb9e5c5550e,但是他们的作用不同,App.vue是顶层路由,指的是组外层的路由,Hello.vue中的是嵌套路由,负责显示子组件。
我把页面截图一下:

 

这个界面,点击最上边的 / 或者/hello 或者/cc的时候,发生变化的是红色路由中的内容。当点击/hello/foo /hello/foo2 /hello/foo3 的时候,发生变化的是下面蓝色路由中的内容。

这样就和我们平时应用十分的相似了。最外层于有变化,或者局部有变化,但是不想全局的发生改变。

同时,这样也符合了模块化,各个模块分别在不同的模块中。
