javascript - 如何在 Vuejs 中过滤具有多个条件的数组？

Question

const app = new Vue({
  el: '#app',
  data: {
    search: '',
    itemsList: [],
    isLoaded: false,
    selectNum: status,
    userList: [{
        id: 1,
        name: "Prem",
        status: "ok"
      },
      {
        id: 2,
        name: "Chandu",
        status: "notok"
      },
      {
        id: 3,
        name: "Shravya",
        status: "ok"
      },
      {
        id: 4,
        name: "kirt",
        status: "notok"
      }
    ]
  },
  created() {
    vm.itemsList = [];
    vm.isLoaded = true;
  },
  computed: {
    filteredAndSorted() {
      // function to compare names  
      function compare(a, b) {
        if (a.name < b.name) return -1;
        if (a.name > b.name) return 1;
        return 0;
      }

      return this.userList.filter(user => {
        return user.name.toLowerCase().includes(this.search.toLowerCase()) &&
          user.status === this.selectNum
      }).sort(compare)
    }
  }
})

<div id="app">
  <div v-if="isLoaded">
    <select v-model="selectNum" name="text">
      <option :value="status">ok</option>
      <option :value="status">notok</option>
    </select>
  </div>
  <div class="search-wrapper">
    <input type="text" v-model="search" placeholder="Search title.." />
    <label>Search Users:</label>
  </div>
  <ul>
    <li v-for="user in filteredAndSorted">{{user.name}}</li>
  </ul>
</div>

我正在努力实现这样的功能，

最初数组将在 v-for 的帮助下加载。在顶部，我有两个选项，称为搜索栏和下拉菜单。在那些人的帮助下，我正在尝试填充数组。

在使用搜索栏的地方，我想过滤数组值。使用下拉菜单，我想过滤每个数组中存在的状态。

尝试像下面的片段:

const app = new Vue ({
  el: '#app',
  data() {
    return {
      search: '',
      itemsList: [],
      isLoaded: false,
      selectNum: '',
      userList: [
        {
          id: 1,
          name: "Prem",
          status:"ok"
        },
        {
          id: 2,
          name: "Chandu",
          status:"notok"
        },
        {
          id: 3,
          name: "Shravya",
          status:"ok"
        },
        {
          id: 4,
          name: "kirt",
          status:"notok"
        }
      ]
    }
  },
  created(){
    this.isLoaded = true;
  },
  computed: {
    filteredAndSorted(){
     function compare(a, b) {
       if (a.name < b.name) return -1;
       if (a.name > b.name) return 1;
       return 0;
     }
     const res = this.userList.filter(user => {
          return user.name.toLowerCase().includes(this.search.toLowerCase())
       }).sort(compare)
     if (this.selectNum) {
       return res.filter(user => user.status === this.selectNum )
     }
     return res
    }
  }
})

        <label>Search Users:</label>

    <li v-for="user in filteredAndSorted">{{user.name}}</li>
  </ul>
</div>
