Javascript - 如何在 Vue.js 中使用多個 arrays 過濾數據？

Question

我正在使用 Vue.js 3 並且在這種情況下我有一個用於一個數組的過濾器類型，但是如何與另一個數組連接，例如這里的一個類別？ 我嘗試了同樣的方法，但我只得到了重復

這是我的代碼

<template>
<div>
   <form>
      <input type="checkbox" name="drama" v-model="filters.drama"/>
      <label for="drama">drama</label>
      <input type="checkbox" name="comedy" v-model="filters.comedy"/>
      <label for="comedy">comedy</label>
      <input type="checkbox" name="horror" v-model="filters.horror"/>
      <label for="horror">horror</label>
      <input type="checkbox" name="polovno" v-model="filters.new"/>
      <label for="new">new</label>
   </form>
   <div v-for="(movie) in filteredMovies" :key="movie.title">
      <div>
        {{ movie.title }}
      </div>
    </div>
</div>
</template>

<script>
  export default {
    data: ()=>({
      filters: {
        horror: true,
        comedy: true,
        drama: true,
        new:true,
        old:true,
      },
      movies: [
        { title: 'Movia A', genres: ['horror'], category:['new']},
        { title: 'Movia B', genres: ['comedy'], category:['old']},
        { title: 'Movia C', genres: ['drama'], category:['new']},
        { title: 'Movia D',genres: ['horror'], category:['new']},
      ]
    }),
    computed: {
      filteredMovies(){
        return this.movies.filter( movie => {
          let selectedGenres = Object.keys(this.filters).filter(item => this.filters[item] === true)
    
                    return movie.genres.some(item => selectedGenres.includes(item))
        })
      },
      filteredMoviesByCategory(){
        return this.movies.filter( movie => {

          let selectedCategory = Object.keys(this.filters).filter(item => this.filters[item] === true)
          
           return movie.category.some(item => selectedCategory.includes(item))
        })
      }
    },


  }
</script>

所以我有復選框，這對於流派過濾非常有效，但是在這種情況下如何將它與另一個數組連接起來呢？ 我是 Vue.js 的新手，這對我有很大幫助

這是 Gif 現在一切如何運作

我找到了一個解決方案，使用其他虛擬數據但有效。
