vue页面是否缓存的两种方式

//在router文件加上meta判断
import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)
export default new Router({
    {//home会被缓存
        path:"/home",
        component:home,
        meta:{keepAlive: true}
    }
    {//hello不会被缓存
        path:"/hello",
        component:hello,
        meta:{keepAlive: false}
    }
})
第二种

// 组件
export default {
  name: 'test-keep-alive',
  data () {
    return {
        includedComponents: "test-keep-alive"
    }
  }
}

<keep-alive include="test-keep-alive">
  <!-- 将缓存name为test-keep-alive的组件 -->
  <component></component>
</keep-alive>

<keep-alive exclude="test-keep-alive"> <!-- 将不缓存name为test-keep-alive的组件 --> <component></component> </keep-alive>
