Textarea 多行文本输入框

标准的多行文本输入框。

import { Textarea } from 'uiw';
// or
import Textarea from '@uiw/react-textarea';

基础用法

import ReactDOM from 'react-dom';
import { Textarea } from 'uiw';

const Demo = () => (
  <div style={{ maxWidth: 300 }}>
    <Textarea placeholder="请输入内容" />
  </div>
)
ReactDOM.render(<Demo />, _mount_);

在表单中使用

<Form /> 表单中应用 <Textarea /> 组件

import React from 'react';
import ReactDOM from 'react-dom';
import { Form, Row, Col, Textarea, Button, Notify } from 'uiw';

const Demo = () => (
  <div>
    <Form
      onSubmitError={(error) => {
        if (error.filed) {
          return { ...error.filed };
        }
        return null;
      }}
      onSubmit={({initial, current}) => {
        const errorObj = {};
        if (!current.commit) {
          errorObj.commit = '内容为空,请输入内容';
        }
        if(Object.keys(errorObj).length > 0) {
          const err = new Error();
          err.filed = errorObj;
          Notify.error({ title: '提交失败!', description: '请确认提交表单是否正确!' });
          throw err;
        }
        Notify.success({
          title: '提交成功!',
          description: `表单提交成功,内容为:${current.commit},将自动填充初始化值!`,
        });
      }}
      fields={{
        commit: {
          children: <Textarea placeholder="请输入说明内容" />
        },
      }}
    >
      {({ fields, state, canSubmit }) => {
        return (
          <div>
            <Row>
              <Col style={{ maxWidth: 300 }}>{fields.commit}</Col>
            </Row>
            <Row>
              <Col fixed>
                <Button disabled={!canSubmit()} type="primary" htmlType="submit">提交</Button>
              </Col>
            </Row>
            <Row>
              <Col>
                <pre style={{ padding: 10 }}>
                  {JSON.stringify(state.current, null, 2)}
                </pre>
              </Col>
            </Row>
          </div>
        )
      }}
    </Form>
  </div>
)
ReactDOM.render(<Demo />, _mount_);

禁用

import { Textarea } from 'uiw';

const Demo = () => (
  <div style={{ maxWidth: 300 }}>
    <Textarea placeholder="请输入内容" disabled />
  </div>
)
ReactDOM.render(<Demo />, _mount_);
