Modal对话框

模态对话框。

何时使用#

需要用户处理事务,又不希望跳转页面以致打断工作流程时,可以使用 Modal 在当前页面正中打开一个浮层,承载相应的操作。

另外当需要一个简洁的确认框询问用户时,可以使用 Modal.confirm() 等语法糖方法。

代码演示

第一个对话框。

expand codeexpand code
import { Modal, Button } from 'antd';

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

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

  handleOk = e => {
    console.log(e);
    this.setState({
      visible: false,
    });
  };

  handleCancel = e => {
    console.log(e);
    this.setState({
      visible: false,
    });
  };

  render() {
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>
          Open Modal
        </Button>
        <Modal
          title="Basic Modal"
          visible={this.state.visible}
          onOk={this.handleOk}
          onCancel={this.handleCancel}
        >
          <p>Some contents...</p>
          <p>Some contents...</p>
          <p>Some contents...</p>
        </Modal>
      </div>
    );
  }
}

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

各种类型的信息提示,只提供一个按钮用于关闭。

expand codeexpand code
import { Modal, Button, Space } from 'antd';

function info() {
  Modal.info({
    title: 'This is a notification message',
    content: (
      <div>
        <p>some messages...some messages...</p>
        <p>some messages...some messages...</p>
      </div>
    ),
    onOk() {},
  });
}

function success() {
  Modal.success({
    content: 'some messages...some messages...',
  });
}

function error() {
  Modal.error({
    title: 'This is an error message',
    content: 'some messages...some messages...',
  });
}

function warning() {
  Modal.warning({
    title: 'This is a warning message',
    content: 'some messages...some messages...',
  });
}

ReactDOM.render(
  <Space>
    <Button onClick={info}>Info</Button>
    <Button onClick={success}>Success</Button>
    <Button onClick={error}>Error</Button>
    <Button onClick={warning}>Warning</Button>
  </Space>,
  mountNode,
);

手动更新和关闭 Modal.method 方式创建的对话框。

expand codeexpand code
import { Modal, Button } from 'antd';

function countDown() {
  let secondsToGo = 5;
  const modal = Modal.success({
    title: 'This is a notification message',
    content: `This modal will be destroyed after ${secondsToGo} second.`,
  });
  const timer = setInterval(() => {
    secondsToGo -= 1;
    modal.update({
      content: `This modal will be destroyed after ${secondsToGo} second.`,
    });
  }, 1000);
  setTimeout(() => {
    clearInterval(timer);
    modal.destroy();
  }, secondsToGo * 1000);
}

ReactDOM.render(<Button onClick={countDown}>Open modal to close in 5s</Button>, mountNode);

使用 Modal.destroyAll() 可以销毁弹出的确认窗。通常用于路由监听当中,处理路由前进、后退不能销毁确认对话框的问题。

expand codeexpand code
import { Modal, Button } from 'antd';
import { ExclamationCircleOutlined } from '@ant-design/icons';

function destroyAll() {
  Modal.destroyAll();
}

const { confirm } = Modal;

function showConfirm() {
  for (let i = 0; i < 3; i += 1) {
    setTimeout(() => {
      confirm({
        icon: <ExclamationCircleOutlined />,
        content: <Button onClick={destroyAll}>Click to destroy all</Button>,
        onOk() {
          console.log('OK');
        },
        onCancel() {
          console.log('Cancel');
        },
      });
    }, i * 500);
  }
}

ReactDOM.render(
  <div>
    <Button onClick={showConfirm}>Confirm</Button>
  </div>,
  mountNode,
);

通过 Modal.useModal 创建支持读取 context 的 contextHolder

expand codeexpand code
import { Modal, Button, Space } from 'antd';

const ReachableContext = React.createContext();
const UnreachableContext = React.createContext();

const config = {
  title: 'Use Hook!',
  content: (
    <div>
      <ReachableContext.Consumer>{name => `Reachable: ${name}!`}</ReachableContext.Consumer>
      <br />
      <UnreachableContext.Consumer>{name => `Unreachable: ${name}!`}</UnreachableContext.Consumer>
    </div>
  ),
};

const App = () => {
  const [modal, contextHolder] = Modal.useModal();

  return (
    <ReachableContext.Provider value="Light">
      <Space>
        <Button
          onClick={() => {
            modal.confirm(config);
          }}
        >
          Confirm
        </Button>
        <Button
          onClick={() => {
            modal.warning(config);
          }}
        >
          Warning
        </Button>
        <Button
          onClick={() => {
            modal.info(config);
          }}
        >
          Info
        </Button>
        <Button
          onClick={() => {
            modal.error(config);
          }}
        >
          Error
        </Button>
      </Space>
      {/* `contextHolder` should always under the context you want to access */}
      {contextHolder}

      {/* Can not access this context since `contextHolder` is not in it */}
      <UnreachableContext.Provider value="Bamboo" />
    </ReachableContext.Provider>
  );
};

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

点击确定后异步关闭对话框,例如提交表单。

expand codeexpand code
import { Modal, Button } from 'antd';

class App extends React.Component {
  state = {
    ModalText: 'Content of the modal',
    visible: false,
    confirmLoading: false,
  };

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

  handleOk = () => {
    this.setState({
      ModalText: 'The modal will be closed after two seconds',
      confirmLoading: true,
    });
    setTimeout(() => {
      this.setState({
        visible: false,
        confirmLoading: false,
      });
    }, 2000);
  };

  handleCancel = () => {
    console.log('Clicked cancel button');
    this.setState({
      visible: false,
    });
  };

  render() {
    const { visible, confirmLoading, ModalText } = this.state;
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>
          Open Modal with async logic
        </Button>
        <Modal
          title="Title"
          visible={visible}
          onOk={this.handleOk}
          confirmLoading={confirmLoading}
          onCancel={this.handleCancel}
        >
          <p>{ModalText}</p>
        </Modal>
      </div>
    );
  }
}

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

使用 confirm() 可以快捷地弹出确认框。onCancel/onOk 返回 promise 可以延迟关闭。

expand codeexpand code
import { Modal, Button, Space } from 'antd';
import { ExclamationCircleOutlined } from '@ant-design/icons';

const { confirm } = Modal;

function showConfirm() {
  confirm({
    title: 'Do you Want to delete these items?',
    icon: <ExclamationCircleOutlined />,
    content: 'Some descriptions',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
}

function showPromiseConfirm() {
  confirm({
    title: 'Do you want to delete these items?',
    icon: <ExclamationCircleOutlined />,
    content: 'When clicked the OK button, this dialog will be closed after 1 second',
    onOk() {
      return new Promise((resolve, reject) => {
        setTimeout(Math.random() > 0.5 ? resolve : reject, 1000);
      }).catch(() => console.log('Oops errors!'));
    },
    onCancel() {},
  });
}

function showDeleteConfirm() {
  confirm({
    title: 'Are you sure delete this task?',
    icon: <ExclamationCircleOutlined />,
    content: 'Some descriptions',
    okText: 'Yes',
    okType: 'danger',
    cancelText: 'No',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
}

function showPropsConfirm() {
  confirm({
    title: 'Are you sure delete this task?',
    icon: <ExclamationCircleOutlined />,
    content: 'Some descriptions',
    okText: 'Yes',
    okType: 'danger',
    okButtonProps: {
      disabled: true,
    },
    cancelText: 'No',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
}

ReactDOM.render(
  <Space>
    <Button onClick={showConfirm}>Confirm</Button>
    <Button onClick={showPromiseConfirm}>With promise</Button>
    <Button onClick={showDeleteConfirm} type="dashed">
      Delete
    </Button>
    <Button onClick={showPropsConfirm} type="dashed">
      With extra props
    </Button>

设置 okTextcancelText 以自定义按钮文字。

expand codeexpand code
import { Modal, Button } from 'antd';
import { ExclamationCircleOutlined } from '@ant-design/icons';

class LocalizedModal extends React.Component {
  state = { visible: false };

  showModal = () => {

      visible: true,
    });
  };

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

  render() {
    return (
      <div>
        <Button type="primary" onClick={this.showModal}>
          Modal
        </Button>
        <Modal
          title="Modal"
          visible={this.state.visible}
          onOk={this.hideModal}
          onCancel={this.hideModal}
          okText="确认"
          cancelText="取消"
        >

          <p>Bla bla ...</p>
          <p>Bla bla ...</p>
        </Modal>
      </div>
    );
  }
}

function confirm() {
  Modal.confirm({
    title: 'Confirm',
    icon: <ExclamationCircleOutlined />,
    content: 'Bla bla ...',
    okText: '确认',
    cancelText: '取消',
  });
}

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


使用 centered 或类似 style.top 的样式来设置对话框位置。

expand codeexpand code
import { Modal, Button } from 'antd';

class App extends React.Component {
  state = {
    modal1Visible: false,
    modal2Visible: false,
  };

  setModal1Visible(modal1Visible) {
    this.setState({ modal1Visible });
  }

  setModal2Visible(modal2Visible) {
    this.setState({ modal2Visible });
  }

  render() {
    return (
      <div>
        <Button type="primary" onClick={() => this.setModal1Visible(true)}>
          Display a modal dialog at 20px to Top
        </Button>
        <Modal
          title="20px to Top"
          style={{ top: 20 }}
          visible={this.state.modal1Visible}
          onOk={() => this.setModal1Visible(false)}
          onCancel={() => this.setModal1Visible(false)}
        >
          <p>some contents...</p>
          <p>some contents...</p>
          <p>some contents...</p>
        </Modal>
        <br />
        <br />
        <Button type="primary" onClick={() => this.setModal2Visible(true)}>
          Vertically centered modal dialog
        </Button>
        <Modal
          title="Vertically centered modal dialog"
          centered
          visible={this.state.modal2Visible}
          onOk={() => this.setModal2Visible(false)}
          onCancel={() => this.setModal2Visible(false)}
        >
          <p>some contents...</p>
          <p>some contents...</p>
          <p>some contents...</p>
        </Modal>
      </div>
    );
  }
}

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

传入 okButtonPropscancelButtonProps 可分别自定义确定按钮和取消按钮的 props。

expand codeexpand code
import { Modal, Button } from 'antd';

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

  showModal = () => {
    this.setState({

  };

  handleOk = e => {
    console.log(e);

  };

  handleCancel = e => {

  • Modal.method() RTL 模式仅支持 hooks 用法。

Modal.method()#

包括:

  • Modal.info

  • Modal.success

  • Modal.error

  • Modal.warning

  • Modal.confirm

以上均为一个函数,参数为 object,具体属性如下:

onCancel取消回调,参数为关闭函数,返回 promise 时 resolve 后自动关闭function(close)-
onOk点击确定回调,参数为关闭函数,返回 promise 时 resolve 后自动关闭function(close)-

以上函数调用后,会返回一个引用,可以通过该引用更新和关闭弹窗。

const modal = Modal.info();

modal.update({
  title: '修改的标题',
  content: '修改的内容',
});

modal.destroy();
  • Modal.destroyAll

使用 Modal.destroyAll() 可以销毁弹出的确认窗(即上述的 Modal.info、Modal.success、Modal.error、Modal.warning、Modal.confirm)。通常用于路由监听当中,处理路由前进、后退不能销毁确认对话框的问题,而不用各处去使用实例的返回值进行关闭(modal.destroy() 适用于主动关闭,而不是路由这样被动关闭)

import { browserHistory } from 'react-router';

// router change
browserHistory.listen(() => {
  Modal.destroyAll();
});

Modal.useModal()#

当你需要使用 Context 时,可以通过 Modal.useModal 创建一个 contextHolder 插入子节点中。通过 hooks 创建的临时 Modal 将会得到 contextHolder 所在位置的所有上下文。创建的 modal 对象拥有与 Modal.method 相同的创建通知方法。

const [modal, contextHolder] = Modal.useModal();

React.useEffect(() => {
  modal.confirm({
    // ...
  });
}, []);

return <div>{contextHolder}</div>;

FAQ#

为什么 Modal 方法不能获取 context、redux 的内容?#

直接调用 Modal 方法,antd 会通过 ReactDOM.render 动态创建新的 React 实体。其 context 与当前代码所在 context 并不相同,因而无法获取 context 信息。

当你需要 context 信息(例如 ConfigProvider 配置的内容)时,可以通过 Modal.useModal 方法会返回 modal 实体以及 contextHolder 节点。将其插入到你需要获取 context 位置即可:

const [modal, contextHolder] = Modal.useModal();

return (
  <Context1.Provider value="Ant">
    {/* contextHolder 在 Context1 内,它可以获得 Context1 的 context */}
    {contextHolder}
    <Context2.Provider value="Design">
      {/* contextHolder 在 Context2 外,因而不会获得 Context2 的 context */}
    </Context2.Provider>
  </Context1.Provider>
);

异同:通过 hooks 创建的 contextHolder 必须插入到子元素节点中才会生效,当你不需要上下文信息时请直接调用。
