Vue3如何对内嵌Iframe组件进行缓存

{
name: 'iframe',
path: '/iframe',
component: Iframe,
},

// 根据路由判断是否显示Iframe 组件
const iframeShow = computed(() => route.value?.path.indexOf('/iframe') === 0);

const state = reactive({
// 保存相同iframe 组件修改之后的组件名称同iframe套壳组件的映射关系
wrapperMap: new Map(),
// wrapperMap 转换成的数组，循环遍历生成iframe组件
iframeComList: [] as any,
});

const wrap = (name:any, query:any, component:any) => {
let wrapper;

const wrapperName = name + '-' + query.catchName;
if (state.wrapperMap.has(wrapperName)) {
wrapper = state.wrapperMap.get(wrapperName);
} else {
wrapper = {
name: wrapperName,

render() {
return h('div', { className: 'vaf-page-wrapper' }, component);
},

};

state.wrapperMap.set(wrapperName, wrapper);
}
return h(wrapper);
};

<!-- :class="{'content-fill':!showAside}" -->
<router-view v-if="!iframeShow" />
<!-- iframe 组件缓存 -->
<div v-show="iframeShow" class="iframe-container">
<component
:is="h(wrapperMap.get(item[0]))"
v-for="(item) in iframeComList"
v-show="iframeShow && item[0] === (String(route?.name) + '-'+ route.query.VIRTUAL_NAME)"
:key="item[0]"
/>
</div>

/**
* 监听路由生成新的iframe 组件并保存
*/
watch(
() => route,
(newValue, oldValue) => {
if (route.value.path.indexOf('/iframe') === 0) {
wrap(route.value.name, route.value.query, h(Iframe));
nextTick(() => {
state.iframeComList = [...state.wrapperMap];
});
}
},
{
deep: true,
immediate: true,
},
);
