vue怎麼刷新目前頁面？以下這篇文章為大家介紹一下vue刷新目前頁面的幾種實作方法，希望對大家有幫助！
專案當中如果做新增/修改/刪除等等操作通常情況下都需要刷新資料或刷新目前頁面.
##思路
- (1)如果頁面簡單,呼叫介面刷新資料即可.
- (2)如果頁面複雜,需要調用多個介面或通知多個子元件做刷新,可以採用刷新目前頁面的方式 下面整理了3種方式來實現刷新當前頁面,每種方式的思路不同,各有優缺點
#實作
方式1-透過location.reload和$router.go(0)方法
#(a)概述
透過location.reload和$router.go(0)都可以實現頁面刷新,它利用瀏覽器刷新功能,相當於按下了f5鍵刷新頁面

##(a)概述
-
透過$router.replace方法,跳轉一個空白頁面,然後再調回之前頁面,它利用
vue-router 切換頁面會把頁面銷毀並新新頁面的功能
#優點
:不會出現頁面空白,使用者體驗好
缺點:網址列會出現快速切換的程序

- 來銷毀和重新建立頁面的方式刷新頁面,並且用到
- provide
和inject實作多層級元件通訊方式,父頁面透過
provide 提供 - reload
方法,子頁面透過inject取得
reload方法,呼叫方法做刷新#優點:不會出現頁面空白,網址列會不會出現快速切換的過程,使用者體驗好
##缺點:實作稍微複雜,涉及到provide
和inject多層級元件間的通訊,和v-if
控制元件建立和銷毀,和$nextTick事件循環的應用程式
