Vue.js 用类星体的infinte涡旋滤波vue

我看到类星体infinte scroll（）是基于将“新”的物体推到模型中

但是我已经使用Getter将我自己变成了一个过滤器（10+个过滤器），Getter返回数据（参见我的代码示例）

我的问题是如何才能做到最好？

• 是否可以实现无限滚动而无需按下它？ 或者页面很难呈现150-200-250，因为它呈现了所有内容
• 我应该这样做吗？它会推动接下来的5个阵列？ 如果是这样的话，我怎么能确定它的第一时间是20秒。下一个是21-40，下一个是41-60…等等

我的代码示例

      {"id": "126", "category": "CCC"},

      {"id": "128", "category": "AAA"}
    ]

  getters: {
    filteredItems: state => currentCategory => {
      if( currentCategory == null ) {
        return state.items;
      }
      return state.items.filter( itm => itm.category == currentCategory );
    }
  }

new Vue({

      <p>This demonstrates how a list of items maintained in Vuex state can be filtered using a getter.  An HTML <code>&lt;select&gt;</code> manipulates a data field "currentCategory" which is bound to the select with a v-model.  The v-model value is used as the parameter to a Vuex getter.</p>
