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 :localelocale !-- 有条件的进行缓存 -- transition modeout-in namefade router-view v-slot{ Component } keep-alive :includeincludeList component :iswrap(route?.name , route.query, Component) :keyroute.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。
