vue keep-alive 使用key后无法缓存

Question

App.vue

<template>
    <div id="app">
        <keep-alive :include="['Page1','Page2']">
            <router-view :key="$route.path"/>
        </keep-alive>
    </div>
</template>

Layout.vue

<template>
    <div>
        <keep-alive :include="['Page1','Page2']">
            <router-view :key="$route.path"/>
        </keep-alive>

        <router-link :to="{name:'Page1'}">page1</router-link>
        <br>
        <router-link :to="{name:'Page2'}">page2</router-link>
        <br>
        <router-link :to="{name:'Page3'}">page3</router-link>
    </div>
</template>

router.ts

const routes: Array<RouteConfig> = [
    {
        path: '', component: () => import('@/views/Layout.vue'),

        children: [
            {
                path: '/page1',
                name: 'Page1',
                component: () => import(/* webpackChunkName: "page1" */ '../views/Page1.vue')
            },
            {
                path: '/page2',
                name: 'Page2',
                component: () => import(/* webpackChunkName: "page2" */ '../views/Page2.vue')
            },
            {
                path: '/page3',
                name: 'Page3',
                component: () => import(/* webpackChunkName: "page3" */ '../views/Page3.vue')
            },
        ]
    },
]

如果吧:key="$route.path"去掉就可以缓存了! 请问咋样写才可以缓存???

Answer 1

你的include 是路由表中的路由名,你的key是路由path,不匹配,不会缓存的
