在路由器视图中的所有路由上保持活动状态

2022-01-25 00:00:00 vue.js vue-router vue-component vuejs2

如果keep-alive被指定给router-view如下

if keep-alive is specified to router-view as below

<keep-alive>
    <router-view></router-view>
</keep-alive>

然后当重新访问该路由时，所有路由都会被有效地缓存和重新加载.

then all routes are effectively cached and reloaded when that route is revisited.

我希望能够在各个路由上指定保持活动选项.

I'd like to be able to specify a keep-alive option on individual routes.

有很多路由，只有 1 或 2 条需要保持活动，而无需重新渲染缓存所有路由是无用的

With many routes and only 1 or 2 that need to be kept alive wihout re-rendering caching all routes is useless

是否有任何方法或任何可用的解决方法

Vue 版本 2.1.0 中的新增功能，include 和 exclude 属性用于有条件地缓存组件.注意 name 选项的使用.

New in Vue version 2.1.0, the include and exclude props for conditionally caching components. Note the use of the name option.

const Foo = {
    name: 'foo',
  template: '<div><p v-for="n in numbers">{{ n }}</p></div>',
  data: function() {
    return {
        numbers: [Math.round(Math.random() * 10), Math.round(Math.random() * 10)]
    }
  }
}

const Bar = {
    name: 'bar',
    template: '<div><p v-for="n in numbers"><strong>{{ n }}</strong></p></div>',
  data: function() {
    return {
        numbers: [Math.round(Math.random() * 10), Math.round(Math.random() * 10)]
    }
  }
}
