render (h) { const filterNode = (value, data) => { if (!value) return true return data[this.$attrs?.props?.label ?? 'label'].indexOf(value) !== -1 } return <div type="align-start" gap="10px" padding> { this.$slots.tree || <el-tree ref="tree" filterNodeMethod={filterNode} {...this.attrsData}/> } { this.$slots.default } </div> }我想把这个filterNode方法。通过{...this.attrsData}这个this.attrsData添加进去

可以将filterNode方法添加到this.attrsData中,然后在render函数中使用解构赋值从this.attrsData中获取filterNode方法,如下所示:
```
render (h) {
const { filterNodeMethod = (value, data) => { if (!value) return true; return data[this.$attrs?.props?.label ?? 'label'].indexOf(value) !== -1 } } = this.attrsData;
const filterNode = filterNodeMethod.bind(this);
return (
<div type="align-start" gap="10px" padding>
{ this.$slots.tree || <el-tree ref="tree" filterNodeMethod={filterNode} {...this.attrsData}/> }
{ this.$slots.default }
</div>
);
}
```
这样,如果在this.attrsData中传递了filterNodeMethod方法,将会覆盖原来的filterNode方法。同时,使用bind方法将this绑定到filterNode方法中,以保证方法中的this指向正确。

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只要export default 下面的内容不用template内的主体内容
好的,以下是将 `ProjectMaterialStatistics.vue` 页面使用 Composition API 重构后的代码,只包含了 `export default` 下面的内容。由于 Vue 2 并不原生支持 Composition API,我们需要借助第三方库 `@vue/composition-api` 来实现这一功能。
首先,安装 `@vue/composition-api`:
```sh
npm install @vue/composition-api
```
然后,在项目入口文件 `main.js` 中全局启用 Composition API:
```js
import Vue from 'vue';
import VueCompositionAPI from '@vue/composition-api';
Vue.use(VueCompositionAPI);
```
接下来是重构后的 `ProjectMaterialStatistics.vue` 文件内容:
```javascript
import Vue from 'vue';
import { reactive, toRefs, onMounted, computed } from '@vue/composition-api';

### 解释
1. **Reactive State**: 使用 `reactive` 创建响应式数据对象,并使用 `toRefs` 将其转换为响应式引用。
2. **Methods**: 所有的方法都直接在 `setup` 函数内部定义,并返回给组件使用。
3. **Life Cycle Hooks**: 使用 `onMounted` 替代 `mounted` 生命周期钩子。
4. **Props and Events**: 如果需要传递或监听事件,可以在 `setup` 函数中进行处理。
这样就完成了将 `ProjectMaterialStatistics.vue` 页面使用 Composition API 重构的工作。希望对你有帮助!
