9，Teleport

允许我们控制在 DOM 中哪个父节点下渲染了 HTML

app.component('modal-button', {
  template: `
    <button @click="modalOpen = true">
        Open full screen modal! (With teleport!)
    </button>

    <teleport to="body">
      <div v-if="modalOpen" class="modal">
        <div>
          I'm a teleported modal! 
          (My parent is "body")
          <button @click="modalOpen = false">
            Close
          </button>
        </div>
      </div>
    </teleport>
  `,
  data() {
    return { 
      modalOpen: false
    }
  }
})

在同一目标上使用多个 teleport
