react实现复选框全选和反选组件效果

本文实例为大家分享了react实现复选框全选和反选组件的具体代码，供大家参考，具体内容如下

运行效果图如下：

代码：

import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
// import Menu from '../menu/Menu.jsx';
class List extends Component {
 constructor () {
 super();
 this.state = {
  title: '我是List的标题',
  content: '我是内容部分部分',
  chooseAll: false, // 全选标志
  inters: ['bsball', 'ymball', 'fbball'], // 页面加载默认选中项
  intersAll: ['bsball', 'ymball', 'ppball', 'fbball'],
  fchoose: false // 正反选标志
 };
 }
 // 全选
 chooseAll (event) {
 let {checked, value} = event.target;
 let chooseAll = this.state.inters.length === 4 ? true : false;
 let inters = ['bsball', 'ymball', 'ppball', 'fbball'];
 checked ? (
  this.setState({
  inters,
  chooseAll: checked
  })
 ) : (
  this.setState({
  inters: [],
  chooseAll: checked
  })
 );
 }
 // 点击复选框
 chooseInter (event) {
 let val = event.target.value;
 let checked = event.target.checked;
 let {inters} = this.state;
 // event.stopPropagation();
 // 选中复选框并且值不在数组里面
 if (checked && !this.state.inters.includes(val)) {
  inters.push(val);
 } else {
  // 取消选中的选项
  inters = inters.filter(v => val !== v);
 }
 let chooseAll = inters.length === 4 ? true : false;
 console.log(inters);
 this.setState({
  inters,
  chooseAll
 });
 }
 // 反选处理
 fchooseHandle (event) {
 let {checked, value} = event.target;
 let {inters, intersAll} = this.state;
 let chooseAll = this.state.inters.length === 4 ? true : false;
 let arr = []; // 反选结果
 this.setState({
  fchoose: checked,
  chooseAll
 });
 intersAll.forEach(item => {
  if (!inters.includes(item)) {
  arr.push(item);
  }
 });
 this.setState({
  inters: arr
 });
 }
 componentWillMount () {
 let chooseAll = this.state.inters.length === 4 ? true : false;
 this.setState({
  chooseAll
 });
 }
 render () {
 return (
  <div className="list">
  {/* <Menu /> */}
  <h1>{this.state.title}</h1>
  <p>{this.state.content}</p>
  <p>
   <label>
   <input type="checkbox" value="bsball" checked={this.state.fchoose} onClick={this.fchooseHandle.bind(this)}/>{this.state.fchoose ? '取消反选' : '反选'}
   </label>
   <label>
   <input type="checkbox" value="bsball" checked={this.state.chooseAll} onClick={this.chooseAll.bind(this)}/>{this.state.chooseAll ? '取消全选' : '全选'}
   </label>
  </p>
  <p>
   <label>
   <input type="checkbox" value="bsball" checked={this.state.inters.includes('bsball')} onClick={this.chooseInter.bind(this)}/>篮球
   </label>
   <label>
   <input type="checkbox" value="ymball" checked={this.state.inters.includes('ymball')} onClick={this.chooseInter.bind(this)}/>羽毛球
   </label>
   <label>
   <input type="checkbox" value="ppball" checked={this.state.inters.includes('ppball')} onClick={this.chooseInter.bind(this)}/>兵乓球
   </label>
   <label>
   <input type="checkbox" value="fbball" checked={this.state.inters.includes('fbball')} onClick={this.chooseInter.bind(this)}/>足球
   </label>
  </p>
  </div>
 );
 }
}
export default withRouter(List);
