设置 okText 与 cancelText 以自定义按钮文字。

en-US

To customize the text of the buttons, you need to set okText and cancelText props.

import { Modal, Button } from 'antd';

class LocalizedModal extends React.Component {
  state = { visible: false }
  showModal = () => {
    this.setState({
      visible: true,
    });
  }
  handleOk = () => {
    this.setState({
      visible: false,
    });
  }
  handleCancel = () => {
    this.setState({
      visible: false,
    });
  }
  render() {
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>Show Modal</Button>
        <Modal title="Modal" visible={this.state.visible}
          onOk={this.handleOk} onCancel={this.handleCancel}
          okText="OK" cancelText="Cancel"
        >
          <p>Bla bla ...</p>
          <p>Bla bla ...</p>
          <p>Bla bla ...</p>
        </Modal>
      </div>
    );
  }
}

function confirm() {
  Modal.confirm({
    title: 'Confirm',
    content: 'Bla bla ...',
    okText: 'OK',
    cancelText: 'Cancel',
  });
}

ReactDOM.render(<div>
  <LocalizedModal />
  <br />
  <Button onClick={confirm}>confirm</Button>
</div>, mountNode);
