Vue實現(xiàn)刷新當前頁面的三種方式總結

更新時間：2023年01月14日 10:19:05 作者：黃金林

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

背景

項目當中如果做新增/修改/刪除等等操作通常情況下都需要刷新數(shù)據(jù)或者刷新當前頁面.

思路

(1)如果頁面簡單,調用接口刷新數(shù)據(jù)即可.

(2)如果頁面復雜,需要調用多個接口或者通知多個子組件做刷新,可以采用刷新當前頁面的方式下面整理了3種方式來實現(xiàn)刷新當前頁面,每種方式的思路不同,各有優(yōu)缺點

實現(xiàn)

方式1-通過location.reload和$router.go(0)方法

(a)概述

通過location.reload和$router.go(0)都可以實現(xiàn)頁面刷新,它利用瀏覽器刷新功能,相當于按下了f5鍵刷新頁面

優(yōu)點:足夠簡單

確定:會出現(xiàn)頁面空白,用戶體驗不好

            <div class="main"><router-view></router-view></div>
        </div>
    `
}
//首頁
let Home = {
    template: `
        <div>
            首頁
            <button @click="onClick">刷新</button>
        </div>
    `,
    created() {
        console.log('首頁加載')
    },
    methods: {
        onClick(){
            // 通localtion.reload或者this.$router.go(0)實現(xiàn)整體刷新頁面,會出現(xiàn)頁面閃爍
            // location.reload()
            this.$router.go(0)
        }
    },
}
//路由配置
let router = new VueRouter({
    routes: [
        {path: '/', component: Layout, children:[
            {path: '', component: Home}
        ]}
    ]
}) 
Vue.use(VueRouter)
//根組件
new Vue({
    router,
    el: '#app'
})
</script>
</html>

方式2-通過空白頁面

(a)概述

通過$router.replace方法,跳轉一個空白頁面,然后再調回之前頁面,它利用vue-router切換頁面會把頁面銷毀并新建新頁面的特性

優(yōu)點:不會出現(xiàn)頁面空白,用戶體驗好

缺點:地址欄會出現(xiàn)快速切換的過程

            首頁
            <button @click="onClick">刷新</button>
        </div>
    `,
    created() {
        console.log('首頁加載')
    },
    methods: {
        onClick(){
            //使用replace跳轉后不會留下 history 記錄,并通過redirect傳遞當前頁面的路徑
            this.$router.replace(`/blank?redirect=${this.$route.fullPath}`)
        }
    },
}
//空白頁面
let Blank = {
    created(){
        console.log('空白頁加載')
        //重新跳回之前的頁面
        this.$router.replace(this.$route.query.redirect)
    },
    template: `
        <div></div>        
    `
}

        {path: '/', component: Layout, children:[

Vue.use(VueRouter)
//根組件
new Vue({
    router,

})

方式3-通過provide和inject

(a)概述

通過在父頁面的<router-view></router-view>上添加v-if的控制來銷毀和重新創(chuàng)建頁面的方式刷新頁面,并且用到provide和inject實現(xiàn)多層級組件通信方式,父頁面通過provide提供reload方法,子頁面通過inject獲取reload方法,調用方法做刷新

優(yōu)點:不會出現(xiàn)頁面空白,地址欄會不會出現(xiàn)快速切換的過程,用戶體驗好

缺點:實現(xiàn)稍復雜,涉及到provide和inject多層級組件間的通信,和v-if控制組件創(chuàng)建和銷毀,和$nextTick事件循環(huán)的應用
