vue.js通过路由实现经典的三栏布局实例代码

<template id="header">
  <div class="header bg-primary text-center">
    <h3>头部区域</h3>
  </div>
</template>
<template id="left">
  <div class="left bg-danger col-lg-2">
    <h3>侧边栏区域</h3>
  </div>
</template>
<template id="main">
  <div class="main bg-info col-lg-10">
    <h3>主体区域</h3>
  </div>
</template>

<div id="app">
  <router-view name="header"></router-view>
  <router-view name="left"></router-view>
  <router-view name="main"></router-view>
</div>

let router = new VueRouter({
  routes: [
    {
      path: '/',
      components: {
        'header': header,
        'left': left,
        'main': main
      }
    }
  ]
});
