一个vue组件包含多个form表单（多个组件）的验证

解决一个页面数据过多导致页面卡顿问题解决方案：一个页面拆分成多个页面实现注意事项:1、父组件引入的子组件要有ref属性，并传入父组件v-model绑定form数据（目的整合所有子组件的form数据）2、子组件通过props接收父组件传来的数据，watch监听父组件传来的数据，将其深拷贝给子的v-model绑定form数据3、子组件正常检验form表单4、父组件提交时，子组件在父组件的验证通过thi

解决大量的表单元素放在一个组件内是会造成页面卡顿的现象

解决方案：一个页面表单拆分成多个页面表单实现

注意事项:

1、父组件引入的子组件要有ref属性，并传入父组件v-model绑定form数据（目的整合所有子组件的form数据）

2、子组件通过props接收父组件传来的数据，watch监听父组件传来的数据，将其深拷贝给子的v-model绑定form数据

3、子组件正常检验form表单

4、父组件提交时，子组件在父组件的验证通过this. $r e f s . A (在父注册的子 r e f 名称) .$ refs.B(子组件form的ref名称)
