更新時(shí)間：2023年01月14日 10:19:05 作者：黃金林

項(xiàng)目當(dāng)中如果做新增/修改/刪除等等操作通常情況下都需要刷新數(shù)據(jù)或者刷新當(dāng)前頁(yè)面。本文為大家整理了三種不同的實(shí)現(xiàn)方法，需要的可以參考一下

背景

項(xiàng)目當(dāng)中如果做新增/修改/刪除等等操作通常情況下都需要刷新數(shù)據(jù)或者刷新當(dāng)前頁(yè)面.

思路

(1)如果頁(yè)面簡(jiǎn)單,調(diào)用接口刷新數(shù)據(jù)即可.

(2)如果頁(yè)面復(fù)雜,需要調(diào)用多個(gè)接口或者通知多個(gè)子組件做刷新,可以采用刷新當(dāng)前頁(yè)面的方式下面整理了3種方式來(lái)實(shí)現(xiàn)刷新當(dāng)前頁(yè)面,每種方式的思路不同,各有優(yōu)缺點(diǎn)

實(shí)現(xiàn)

方式1-通過(guò)location.reload和$router.go(0)方法

(a)概述

通過(guò)location.reload和$router.go(0)都可以實(shí)現(xiàn)頁(yè)面刷新,它利用瀏覽器刷新功能,相當(dāng)于按下了f5鍵刷新頁(yè)面

優(yōu)點(diǎn):足夠簡(jiǎn)單

確定:會(huì)出現(xiàn)頁(yè)面空白,用戶體驗(yàn)不好

            // location.reload()
            this.$router.go(0)
        }
    },
}
//路由配置
let router = new VueRouter({
    routes: [
        {path: '/', component: Layout, children:[

new Vue({

方式2-通過(guò)空白頁(yè)面

(a)概述

通過(guò)$router.replace方法,跳轉(zhuǎn)一個(gè)空白頁(yè)面,然后再調(diào)回之前頁(yè)面,它利用vue-router切換頁(yè)面會(huì)把頁(yè)面銷毀并新建新頁(yè)面的特性

優(yōu)點(diǎn):不會(huì)出現(xiàn)頁(yè)面空白,用戶體驗(yàn)好

缺點(diǎn):地址欄會(huì)出現(xiàn)快速切換的過(guò)程

方式3-通過(guò)provide和inject

(a)概述

通過(guò)在父頁(yè)面的<router-view></router-view>上添加v-if的控制來(lái)銷毀和重新創(chuàng)建頁(yè)面的方式刷新頁(yè)面,并且用到provide和inject實(shí)現(xiàn)多層級(jí)組件通信方式,父頁(yè)面通過(guò)provide提供reload方法,子頁(yè)面通過(guò)inject獲取reload方法,調(diào)用方法做刷新

優(yōu)點(diǎn):不會(huì)出現(xiàn)頁(yè)面空白,地址欄會(huì)不會(huì)出現(xiàn)快速切換的過(guò)程,用戶體驗(yàn)好

缺點(diǎn):實(shí)現(xiàn)稍復(fù)雜,涉及到provide和inject多層級(jí)組件間的通信,和v-if控制組件創(chuàng)建和銷毀,和$nextTick事件循環(huán)的應(yīng)用
