Input输入框
需要用户输入表单域内容时。
提供组合型输入框,带搜索的输入框,还可以进行大小选择。
基本使用。
用于配置一些固定组合。
const { Option } = Select;
const selectBefore = (
<Select defaultValue="Http://" style={{ width: 90 }}>
<Option value="Http://">Http://</Option>
<Option value="Https://">Https://</Option>
</Select>
);
const selectAfter = (
<Select defaultValue=".com" style={{ width: 80 }}>
<Option value=".com">.com</Option>
<Option value=".jp">.jp</Option>
<Option value=".cn">.cn</Option>
<Option value=".org">.org</Option>
</Select>
);
ReactDOM.render(
<div>
<div style={{ marginBottom: 16 }}>
<Input addonBefore="Http://" addonAfter=".com" defaultValue="mysite" />
</div>
<div style={{ marginBottom: 16 }}>
<Input addonBefore={selectBefore} addonAfter={selectAfter} defaultValue="mysite" />
</div>
<div style={{ marginBottom: 16 }}>
<Input addonAfter={<Icon type="setting" />} defaultValue="mysite" />
</div>
</div>,
mountNode,
);
带有搜索按钮的输入框,2.5.0
时新增。
import { Input } from 'antd';
const { Search } = Input;
ReactDOM.render(
<div>
<Search
placeholder="input search text"
onSearch={value => console.log(value)}
style={{ width: 200 }}
/>
<br />
<br />
<Search placeholder="input search text" onSearch={value => console.log(value)} enterButton />
<br />
<br />
<Search
placeholder="input search text"
enterButton="Search"
size="large"
onSearch={value => console.log(value)}
/>
</div>,
mountNode,
);
import { Input } from 'antd';
const { TextArea } = Input;
ReactDOM.render(
<div>
<TextArea placeholder="Autosize height based on content lines" autosize />
<div style={{ margin: '24px 0' }} />
<TextArea
placeholder="Autosize height with minimum and maximum number of lines"
autosize={{ minRows: 2, maxRows: 6 }}
/>
</div>,
mountNode,
);
在输入框上添加前缀或后缀图标。
import { Input, Tooltip, Icon } from 'antd';
ReactDOM.render(
<Input
placeholder="Enter your username"
prefix={<Icon type="user" style={{ color: 'rgba(0,0,0,.25)' }} />}
suffix={
<Tooltip title="Extra information">
<Icon type="info-circle" style={{ color: 'rgba(0,0,0,.45)' }} />
</Tooltip>
/>,
mountNode,
);
带移除图标的输入框,点击图标删除所有内容。
我们为 <Input />
输入框定义了三种尺寸(大、默认、小),高度分别为 40px
、32px
和 24px
。
import { Input } from 'antd';
ReactDOM.render(
<div className="example-input">
<Input size="large" placeholder="large size" />
<Input placeholder="default size" />
<Input size="small" placeholder="small size" />
</div>,
mountNode,
);
width: 200px;
margin: 0 8px 8px 0;
}
输入框的组合展现。
注意:使用 compact
模式时,不需要通过 Col
来控制宽度。
import { Input, Col, Row, Select, InputNumber, DatePicker, AutoComplete, Cascader } from 'antd';
const InputGroup = Input.Group;
const { Option } = Select;
const options = [
{
value: 'zhejiang',
label: 'Zhejiang',
children: [
{
value: 'hangzhou',
label: 'Hangzhou',
children: [
{
value: 'xihu',
label: 'West Lake',
},
],
},
],
},
{
value: 'jiangsu',
label: 'Jiangsu',
children: [
{
value: 'nanjing',
label: 'Nanjing',
children: [
{
value: 'zhonghuamen',
label: 'Zhong Hua Men',
},
],
},
],
},
];
class CompactDemo extends React.Component {
state = {
dataSource: [],
};
handleChange = value => {
this.setState({
dataSource:
!value || value.indexOf('@') >= 0
? []
: [`${value}@gmail.com`, `${value}@163.com`, `${value}@qq.com`],
});
};
render() {
return (
<div>
<InputGroup size="large">
<Row gutter={8}>
<Col span={5}>
<Input defaultValue="0571" />
</Col>
<Col span={8}>
<Input defaultValue="26888888" />

<Input style={{ width: 100, textAlign: 'center', borderLeft: 0 }} placeholder="Maximum" />
</InputGroup>
<br />
<InputGroup compact>
<Select defaultValue="Sign Up">
<Option value="Sign Up">Sign Up</Option>
<Option value="Sign In">Sign In</Option>
</Select>
<AutoComplete
dataSource={this.state.dataSource}
style={{ width: 200 }}
onChange={this.handleChange}
placeholder="Email"
/>
</InputGroup>
<br />
<InputGroup compact>
<Select style={{ width: '30%' }} defaultValue="Home">
<Option value="Home">Home</Option>
<Option value="Company">Company</Option>
</Select>
<Cascader style={{ width: '70%' }} options={options} placeholder="Select Address" />
</InputGroup>
</div>
);
}
}
ReactDOM.render(<CompactDemo />, mountNode);
用于多行输入。
import { Input } from 'antd';
const { TextArea } = Input;
ReactDOM.render(<TextArea rows={4} />, mountNode);
结合 Tooltip 组件,实现一个数值输入框,方便内容超长时的全量展现。
/* to prevent the arrow overflow the popup container,
or the height is not enough when content is empty */
.numeric-input .ant-tooltip-inner {
min-width: 32px;
min-height: 37px;
}
.numeric-input .numeric-input-title {
font-size: 14px;
}

import { Input } from 'antd';
ReactDOM.render(<Input.Password placeholder="input password" />, mountNode);
