初学vue3与ts：keep-alive的简单使用

vue2用法

<keep-alive :include="keepAliveNames">
	<router-view>router-view>
keep-alive>
<script>
	//include代表缓存name是FleetList的组件
	this.keepAliveNames = 'FleetList'
script>

vue3用法

<router-view v-slot="{ Component }">
	<keep-alive :include="keepAliveNames">
		<component :is="Component">component>
	keep-alive>
router-view>
<script setup>
	//include代表缓存name是FleetList的组件
	const keepAliveNames = ref('FleetList')
script>

不要问Component 是什么，这么写就对了。
ps：因为我也不知道Component 是什么，折腾了好久才明白。不要问，问就是:is=“Component"的跟v-slot=”{ Component }"一样就对了
