## 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。

## en-US

A more complex example, as illustrated in this example, we 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.

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

const Test = React.createClass({
  getInitialState() {
    return {
      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() {
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>
          Open modal dialog
        </Button>
        <Modal
          visible={this.state.visible}
          title="Title"
          onOk={this.handleOk}
          onCancel={this.handleCancel}
          footer={[
            <Button key="back" size="large" onClick={this.handleCancel}>Return</Button>,
            <Button key="submit" type="primary" size="large" loading={this.state.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(<Test />, mountNode);
