Vue コンポーネントでグローバル登録とローカル登録を実装する方法

Vue.component('tab-title',{
   props:['title'],
   template:&#39;<li v-on:click="$emit(\&#39;change\&#39;)">{{title}}</li>&#39;
 })
 Vue.component(&#39;tab-content&#39;,{
   props:[&#39;content&#39;],
   template:&#39;<p>{{content}}</p>&#39;
 })

<p id="app">
  <ul class="navTab">
   <li v-for="(navTab,index) in navTabs" is="tab-title" v-bind:info="navTab.text" v-bind:class="{active:navTab.isActive}" v-on:addactive="switchActive(index)"></li>
  </ul>
  <p class="tabContent">
   <p v-for="navTab in navTabs" is="tab-content" v-bind:content="navTab.tabContent" 
   v-bind:class="[&#39;tab-panel&#39;,{active:navTab.isActive}]" v-if="navTab.isActive"></p>
  </p>
  </p>

var app=new Vue({
      el: '#app',
     components: {
       'tab-title': {
        props:['info'],//接受父元素传递的参数
        template:&#39;<li v-on:click="$emit(\&#39;addactive\&#39;)">{{info}}</li>&#39;//点击时传递通过$emit子元素传递给父元素调用 addactive方法（不能使用驼峰写法）
        },
       &#39;tab-content&#39;:{
         props:["content"],
        template:&#39;<p>{{content}}</p>&#39;
       }
