邏輯導航
1.當點擊頁面主頁的登錄/注冊按鈕時，彈出登錄/注冊模態框
2.登錄/注冊模態框也是一個小組件，在組件檔案夾內創建對應組件
3.然后需要將該組件傳到header（頭部）組件內（進行相關的匯入和注冊）
4.
補充子傳父組件語法
在子組件內
當點擊子組件里的東西時，傳遞給父組件一個事件，父組件該事件也會執行相應的操作處理一些東西
methods: {
close_login() {
// 子傳父組件，this.$emit給父組件傳遞一個事件
this.$emit('close')
},
在父組件內
語法為@子組件傳來的事件名=“父組件自己的事件名”
<Login v-if="is_login" @close="close_login" @go="put_register" @loginsuccess="login_success"/>
