一组备选项中进行多选
import { Checkbox } from 'uiw';
// or
import Checkbox from '@uiw/react-checkbox';
单独使用可以表示两种状态之间的切换,半选中只是样式上的表现。
import React from 'react';
import { Checkbox } from 'uiw';
export default function Demo() {
return(
<div>
<Checkbox onChange={(e) =>{
console.log(e.target.checked)
console.log(e.target)
}}>未选中</Checkbox>
<Checkbox checked >选中</Checkbox>
</div>
);
}
import React from 'react';
import { Form, Checkbox, Row, Col, Button, Notify } from 'uiw';
const Demo = () => (
<div>
<Form
onChange={({ initial, current }) => {
console.log('onChange~~~:::', initial, current);
}}
onSubmit={({initial, current}) => {
console.log('onSubmit~~~:::', initial, current)
Notify.success({
title: '提交成功!',
description: `选项为:【${current.checkbox}】【${JSON.stringify(current.checkboxGroup)}】,提交完成,将自动填充初始化值!`,
});
}}
fields={{
checkbox: {
inline: true,
initialValue: true,
label: '单选条件',
children: <Checkbox>四川菜</Checkbox>,
validator: (value) => {
return !value ? '必须统一服务条款' : null;
},
},
checkboxGroup: {
initialValue: ['四川菜'],
label: '选择你想吃的菜',
children: (
<Checkbox.Group>
<div>菜系</div>
<Checkbox value="四川菜">四川菜</Checkbox>
<Checkbox value="湖北菜">湖北菜</Checkbox>
<Checkbox value="西北菜">西北菜</Checkbox>
<Checkbox disabled value="新疆菜">新疆菜</Checkbox>
<Checkbox value="东北菜">东北菜</Checkbox>
<div style={{ marginTop: 10 }}>家常菜</div>
<Checkbox value="红烧武昌鱼">红烧武昌鱼</Checkbox>
<Checkbox value="麻婆豆腐">麻婆豆腐</Checkbox>
<Checkbox value="北京烤鸭">北京烤鸭</Checkbox>
</Checkbox.Group>
),
},
}}
>
{({ fields, state, canSubmit }) => {
return (
<div>
<Row>
<Col>{fields.checkbox}</Col>
</Row>
<Row>
<Col>{fields.checkboxGroup}</Col>
</Row>
<Row>
<Col>
<Button disabled={!canSubmit()} type="primary" htmlType="submit">
提交
</Button>
</Col>
</Row>
<Row>
<Col>
<pre style={{ padding: 10, marginTop: 10 }}>
{JSON.stringify(state.current, null, 2)}
</pre>
</Col>
</Row>
</div>
)
}}
</Form>
</div>
)
export default Demo;
通过设置 disabled
属性来禁用多选框。
import React from 'react';
import { Checkbox } from 'uiw';
export default function Demo() {
return(
<div>
<Checkbox disabled checked>未选中禁用</Checkbox>
<Checkbox disabled checked>选中禁用</Checkbox>
<Checkbox disabled indeterminate>半选中禁用</Checkbox>
</div>
);
}
import React from 'react';
import { Checkbox, Divider } from 'uiw';
const checkedList = [ '四川菜', '湖北菜', '西北菜', '新疆菜', '东北菜' ];
class Demo extends React.Component {
constructor(props) {
super(props);
this.state = {
value: ['四川菜', '新疆菜'],
indeterminate: true,
checkAll: false,
};
}
onChange(e, list) {
console.log('list', list);
console.log('list', checkedList);
this.setState({
value: list,
indeterminate: !!list.length && (list.length < checkedList.length),
checkAll: list.length === checkedList.length,
});
}
onCheckAllChange(e) {
this.setState({
value: e.target.checked ? checkedList : [],
indeterminate: false,
checkAll: e.target.checked,
});
}
render() {
const { indeterminate, checkAll } = this.state;
return (
<div>
<Checkbox checked={checkAll} indeterminate={indeterminate} onChange={this.onCheckAllChange.bind(this)}>全选</Checkbox>
<Divider />
<Checkbox.Group name="cuisine" value={this.state.value} onChange={this.onChange.bind(this)}>
{checkedList.map((item, idx) => {
return (
<Checkbox key={idx} value={item}>{item}</Checkbox>
)
})}
</Checkbox.Group>
</div>
)
}
}
export default Demo;
方便的从数组生成 Checkbox
组。
import React from 'react';
import { Checkbox, Divider, Button } from 'uiw';
class Demo extends React.Component {
constructor(props) {
super(props);
this.state = {
value: ['四川菜', '新疆菜'],
};
}
onChange(e, list) {
console.log('Value:-->', e.target.value, list);
this.setState({ value: list });
}
render() {
return (
<div>
<Checkbox.Group name="cuisine" value={this.state.value} onChange={this.onChange.bind(this)}>
<div>川菜</div>
<Checkbox value="四川菜">四川菜</Checkbox>
<Checkbox value="湖北菜">湖北菜</Checkbox>
<div>本帮江浙菜</div>
<Checkbox value="西北菜">西北菜</Checkbox>
<Checkbox value="新疆菜">新疆菜</Checkbox>
<div>家常菜</div>
<Checkbox value="东北菜">东北菜</Checkbox>
<Checkbox value="北京烤鸭">北京烤鸭</Checkbox>
</Checkbox.Group>
<Divider />
<Button
type="primary"
onClick={() => {
// console.log('set::', ['东北菜', '北京烤鸭']);
this.setState({ value: ['东北菜', '北京烤鸭'] });
}}
>
选中两个
</Button>
</div>
)
}
}
export default Demo;
通过 checked
属性改变 Checkbox
组件状态。
import React from 'react';
import { Checkbox, Button } from 'uiw';
class Demo extends React.Component {
constructor(props) {
super(props);
this.state = {
checked: true
}
}
onChange(e) {
console.log('e.target.checked:', e.target.checked);
this.setState({ checked: e.target.checked });
}
render() {
return (
<div>
<Checkbox onChange={this.onChange.bind(this)} checked={this.state.checked} style={{ marginRight: 10 }} />
<Button
size="small"
type="primary"
onClick={() => {
this.setState({ checked: !this.state.checked });
}}
>
点击按钮改变 Checkbox 状态
</Button>
</div>
)
}
}
export default Demo;
