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 (


);
}
}
export default withRouter(List);
import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
// import Menu from '../menu/Menu.jsx';
class List extends Component {

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)) {

this.setState({

chooseAll
});
intersAll.forEach(item => {

if (!inters.includes(item)) {

arr.push(item);

}
});
this.setState({

});
}
componentWillMount () {
let chooseAll = this.state.inters.length === 4 ? true : false;
this.setState({

chooseAll
});
}
render () {
return (


);
}
}
export default withRouter(List); 以上就是本文的全部内容，希望对大家的学习有所帮助。
