vue3调用方法用filter把数组里面的status等于false，true分别拿出来放在新

在 Vue.js 3 中，你可以使用 `map` 或者 `filter` 方法结合数组的逻辑处理来达到这个目的。假设你有一个数组 `items`，其中包含 `status` 属性，你可以这样做：

let items = [
  { id: 1, status: true },
  { id: 2, status: false },
  { id: 3, status: true },
  { id: 4, status: false }
];

// 使用 filter 方法过滤出 status 为 true 和 false 的元素，并将它们分别放入两个新的数组
let trueItems = items.filter(item => item.status === true);
let falseItems = items.filter(item => item.status === false);

console.log('True items:', trueItems);
console.log('False items:', falseItems);

这里我们创建了两个新数组 `trueItems` 和 `falseItems`，它们分别存储了原数组中 `status` 为 `true` 和 `false` 的项。

vue3调用方法用filter把ref相应的数组里面的status等于false，true分别拿出来

在Vue 3中，如果你有一个`ref`对象存储了一个数组，并且你想通过`filter()`方法根据`status`属性筛选出状态为`false`和`true`的元素，你可以这样做：

// 假设你有一个名为`myArrayRef`的Vue ref，它包含一个数组
const myArrayRef = ref([]);

// 当你需要过滤时，可以这样操作：
// 获取ref数组的当前值
const array = myArrayRef.value;

// 使用filter方法根据status属性
const falseItems = array.filter(item => item.status === false);
const trueItems = array.filter(item => item.status === true);

// 现在，`falseItems`和`trueItems`分别包含了status为false和true的元素

如果你想直接在一个函数中一次性处理这个操作，可以将上述步骤封装成一个计算属性或者方法：

methods: {
  filterByStatus(status) {
    return this.myArrayRef.value.filter(item => item.status === status);
  }
}

// 调用时，例如获取所有status为false的元素：
const falseElements = this.filterByStatus(false);

把文件中的页面使用Composition API重构要求用vue2完成并详细到每个方法

为了将文件中的代码从Options API重构为Composition API，并保持Vue 2的支持，我们可以使用`@vue/composition-api`插件。以下是详细的重构步骤和代码：

### 安装依赖
首先，需要安装`@vue/composition-api`插件：

npm install @vue/composition-api

### 主要更改点
1. **引入 Composition API**：在组件中引入`setup`函数和其他Composition API相关的钩子。
2. **状态管理**：使用`reactive`或`ref`来声明响应式数据。
3. **生命周期钩子**：使用相应的Composition API钩子，如`onMounted`、`onCreated`等。
4. **方法提取**：将原有的方法提取到`setup`函数中。

### 重构后的代码
