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 { Button, Modal } from 'antd';
import React, { useState } from 'react';

const App: React.FC = () => {
  const [isModalVisible, setIsModalVisible] = useState(false);

  const showModal = () => {
    setIsModalVisible(true);
  };

  const handleOk = () => {
    setIsModalVisible(false);
  };

  const handleCancel = () => {
    setIsModalVisible(false);
  };

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

export default App;

各种类型的信息提示,只提供一个按钮用于关闭。

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

const 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() {},
  });
};

const success = () => {
  Modal.success({
    content: 'some messages...some messages...',
  });
};

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

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

const App: React.FC = () => (
  <Space wrap>
    <Button onClick={info}>Info</Button>
    <Button onClick={success}>Success</Button>
    <Button onClick={error}>Error</Button>
    <Button onClick={warning}>Warning</Button>
  </Space>
);

export default App;

手动更新和关闭 Modal.method 方式创建的对话框。

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

const 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);
};

const App: React.FC = () => <Button onClick={countDown}>Open modal to close in 5s</Button>;

export default App;

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 { ExclamationCircleOutlined } from '@ant-design/icons';
import { Button, Modal } from 'antd';
import React from 'react';

const { confirm } = Modal;

const destroyAll = () => {
  Modal.destroyAll();
};

const 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);
  }
};

const App: React.FC = () => <Button onClick={showConfirm}>Confirm</Button>;

export default App;

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

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

const ReachableContext = createContext<string | null>(null);
const UnreachableContext = createContext<string | null>(null);

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

const App: React.FC = () => {
  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>
  );
};

export default App;

使用 width 来设置模态对话框的宽度。

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

const App: React.FC = () => {
  const [visible, setVisible] = useState(false);

  return (
    <>
      <Button type="primary" onClick={() => setVisible(true)}>
        Open Modal of 1000px width
      </Button>
      <Modal
        title="Modal 1000px width"
        centered
        visible={visible}
        onOk={() => setVisible(false)}
        onCancel={() => setVisible(false)}
        width={1000}
      >
        <p>some contents...</p>
        <p>some contents...</p>
        <p>some contents...</p>
      </Modal>
    </>
  );
};

export default App;

点击确定后异步关闭对话框,例如提交表单。

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

const App: React.FC = () => {
  const [visible, setVisible] = useState(false);
  const [confirmLoading, setConfirmLoading] = useState(false);
  const [modalText, setModalText] = useState('Content of the modal');

  const showModal = () => {
    setVisible(true);
  };

  const handleOk = () => {
    setModalText('The modal will be closed after two seconds');
    setConfirmLoading(true);
    setTimeout(() => {
      setVisible(false);
      setConfirmLoading(false);
    }, 2000);
  };

  const handleCancel = () => {
    console.log('Clicked cancel button');
    setVisible(false);
  };

  return (
    <>
      <Button type="primary" onClick={showModal}>
        Open Modal with async logic
      </Button>
      <Modal
        title="Title"
        visible={visible}
        onOk={handleOk}
        confirmLoading={confirmLoading}
        onCancel={handleCancel}
      >
        <p>{modalText}</p>
      </Modal>
    </>
  );
};

export default App;

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 { ExclamationCircleOutlined } from '@ant-design/icons';
import { Button, Modal, Space } from 'antd';
import React from 'react';

const { confirm } = Modal;

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

const 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() {},
  });
};

const 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');
    },
  });
};

const showPropsConfirm = () => {
  confirm({
    title: 'Are you sure delete this task?',

    content: 'Some descriptions',
    okText: 'Yes',
    okType: 'danger',
    okButtonProps: {
      disabled: true,
    },
    cancelText: 'No',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
};

const App: React.FC = () => (

  • <Modal /> 和 Form 一起配合使用时,设置 destroyOnClose 也不会在 Modal 关闭时销毁表单字段数据,需要设置 <Form preserve={false} />

  • 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:

const modal = Modal.info();

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

// 在 4.8.0 或更高版本中,可以通过传入函数的方式更新弹窗
modal.update(prevConfig => ({
  ...prevConfig,
  title: `${prevConfig.title}(新)`,
}));

modal.destroy();
  • Modal.destroyAll

使用 Modal.destroyAll() 可以销毁弹出的确认窗(即上述的 Modal.infoModal.successModal.errorModal.warningModal.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 关闭时,内容不会更新?#

Modal 在关闭时会将内容进行 memo 从而避免关闭过程中的内容跳跃。也因此如果你在配合使用 Form 有关闭时重置 initialValues 的操作,请通过在 effect 中调用 resetFields 来重置。

为什么 Modal 方法不能获取 context、redux、的内容和 ConfigProvider locale/prefixCls 配置?#

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。

如何关闭 Modal 动画?#

你可以通过 transitionName=""maskTransitionName="" 去除动画 CSS,但是需要注意的是。该方法为内部方法,我们不保证下个大版本重构时该属性会被保留。

静态方法如何设置 prefixCls ?#

你可以通过 ConfigProvider.config 进行设置。
