鹤壁人民医院网站谁做的想做个网络推广

1：使用场景

     从列表页跳转至不同的详情页面，对这些详情页面分别进行缓存

2：核心代码

2.1: 配置路由文件

在路由文件里对需要进行缓存的路由对象添加meta 属性

 // 需要缓存的详情页面路由
  {
    name: detail,
    path: '/myRouter/detail', // 路径
    component: () => import('../views/abc/detail.vue'),
    meta: {
      keepAlive: true, // 是否被缓存
    },
  },

2.2: app页面增加缓存逻辑

<template>
  <el-config-provider :locale="locale">
    <!-- 有条件的进行缓存 -->
    <transition mode="out-in" name="fade">

      <router-view v-slot="{ Component }">
        <keep-alive :include="includeList">
          <component :is="wrap(route?.name , route.query, Component)" :key="route.fullPath" />
        </keep-alive>
      </router-view>
    </transition>
  </el-config-provider>
</template>

wrap 方法

    const wrapperMap = new Map();const wrap = (name:any, query:any, component:any) => {let wrapper;let wrapperName;if(query.catchName){wrapperName = name + '-' + query.catchName;}else {wrapperName  = name;}if (wrapperMap.has(wrapperName)) {wrapper = wrapperMap.get(wrapperName);} else {wrapper = {name: wrapperName,render() {return h('div', { className: 'vaf-page-wrapper' }, component);},};wrapperMap.set(wrapperName, wrapper);}return h(wrapper);};

watch 监听对于route.query 是否存在catchName 参数的路由分别进行缓存

// 监听路由，判断页面是否需要缓存watch(() => route,(newVal: any, oldVal) => {if (newVal.query?.catchName) {if (newVal.meta.keepAlive && !state.includeList.includes(newVal.name + '-' + newVal.query?.catchName)) {state.includeList.push(newVal.name + '-' + newVal.query?.catchName);}} else if (newVal.meta.keepAlive && !state.includeList.includes(newVal.name)) {state.includeList.push(newVal.name);}},{deep: true, // 开启深度监听},);

2.3: 在列表页面的查看点击方法中配置路由添加query 传参 catchName

注：上面为核心代码逻辑，需要根据实际情况进行调整。
