## zh-CN

更复杂的例子，自定义了页脚的按钮，点击提交后进入 loading 状态，完成后关闭。

不需要默认确定取消按钮时，你可以把 `footer` 设为 `null`。

## en-US

A more complex example which define a customized footer button bar,
the dialog will change to loading state after clicking submit button, when the loading is over,
the modal dialog will be closed.

You could set `footer` to `null` if you don't need default footer buttons.

````jsx
import { Modal, Button } from 'antd';

class App extends React.Component {
  state = {
    loading: false,
    visible: false,
  }

  showModal = () => {
    this.setState({
      visible: true,
    });
  }

  handleOk = () => {
    this.setState({ loading: true });
    setTimeout(() => {
      this.setState({ loading: false, visible: false });
    }, 3000);
  }

  handleCancel = () => {
    this.setState({ visible: false });
  }

  render() {
    const { visible, loading } = this.state;
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>
          Open Modal with customized footer
        </Button>
        <Modal
          visible={visible}
          title="Title"
          onOk={this.handleOk}
          onCancel={this.handleCancel}
          footer={[
            <Button key="back" onClick={this.handleCancel}>Return</Button>,
            <Button key="submit" type="primary" loading={loading} onClick={this.handleOk}>
              Submit
            </Button>,
          ]}
        >
          <p>Some contents...</p>
          <p>Some contents...</p>
          <p>Some contents...</p>
          <p>Some contents...</p>
          <p>Some contents...</p>
        </Modal>
      </div>
    );
  }
}

ReactDOM.render(<App />, mountNode);
