1.当点击页面主页的登录/注册按钮时,弹出登录/注册模态框
2.登录/注册模态框也是一个小组件,在组件文件夹内创建对应组件
3.然后需要将该组件传到header(头部)组件内(进行相关的导入和注册)

补充子传父组件语法

在子组件内

当点击子组件里的东西时,传递给父组件一个事件,父组件该事件也会执行相应的操作处理一些东西

 methods: {     close_login() {         // 子传父组件,this.$emit给父组件传递一个事件       this.$emit('close')     }, 

在父组件内

语法为@子组件传来的事件名=“父组件自己的事件名”

<Login v-if="is_login" @close="close_login" @go="put_register" @loginsuccess="login_success"/> 

登录组件
