首页登录注册模态框搭建

IT技术3年前更新 IT大王

逻辑导航

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）
4.

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
