浅谈Vue内置component组件的应用场景

<!-- 动态组件由 vm 实例的属性值 `componentId` 控制 -->
<component :is="componentId"></component>

<template>
 <div>
	<a href="javascript:;" rel="external nofollow" rel="external nofollow" @click.prevent="handleCloseBtnClick"></a>
	<div>
	 <h3>新用户注册</h3>
	 <div>
		<span :class="{active: type === 'mobileForm'}" @click="type = mobileForm">手机注册</span>
		<span :class="{active: type === 'emailForm'}" @click="type = emailForm">邮箱注册</span>
	 </div>
	</div>
	<component :is="type" ref="form">
	 <button @click="handleRegisterBtnClick">注册</button>
	 <div ><span ><span>注册视为同意</span><a> 《法律条款和隐私说明》</a></span></div>
	 <div><span>已有账号<a href="javascript:;" rel="external nofollow" rel="external nofollow" @click.prevent="handleLoginBtnClick">直接登入>></a></span></div>
	</component>
 </div>
