在React中从api获取数据后应用过滤器

import React, { Component } from 'react';

class DataComponent extends Component {
  state = {
    data: [],
    filteredData: [],
  };

  componentDidMount() {
    fetch('api-url')
      .then(response => response.json())
      .then(data => {
        this.setState({ data, filteredData: data });
      })
      .catch(error => {
        console.error('Error fetching data:', error);
      });
  }

  applyFilter = (filter) => {
    const filteredData = this.state.data.filter(item => {
      // 这里可以根据特定的条件进行过滤
      // 例如 item.name.includes(filter) 进行名称过滤
      return true; // 返回true表示保留该数据项
    });

    this.setState({ filteredData });
  }

  render() {
    return (
      <div>
        <FilterComponent applyFilter={this.applyFilter} />

        {this.state.filteredData.map(item => (
          <div key={item.id}>{item.name}</div>
        ))}
      </div>
    );
  }
}

class FilterComponent extends Component {
  state = {
    filter: '',
  };

  handleChange = (event) => {
    this.setState({ filter: event.target.value });
  }

  handleClick = () => {
    this.props.applyFilter(this.state.filter);
  }

  render() {
    return (
      <div>
        <input type="text" value={this.state.filter} onChange={this.handleChange} />
        <button onClick={this.handleClick}>Apply Filter</button>
      </div>
    );
  }
}

export default DataComponent;
