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

基本

第一个对话框。

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);

自定义页脚

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。

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);

确认对话框

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

import { Modal, Button } from 'antd';
const confirm = Modal.confirm;
function showConfirm() {
  confirm({
    title: 'Do you want to delete these items?',
    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() {},
  });
}
ReactDOM.render(<Button onClick={showConfirm}>Confirm</Button>, mountNode);

国际化

设置 okText 与 cancelText 以自定义按钮文字。

import { Modal, Button } from 'antd';
class LocalizedModal extends React.Component {
  state = { visible: false };
  showModal = () => {
    this.setState({
      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>
          <p>Bla bla ...</p>
        </Modal>
      </div>
    );
  }
}
function confirm() {
  Modal.confirm({
    title: 'Confirm',
    content: 'Bla bla ...',
    okText: '确认',
    cancelText: '取消',
  });
}
ReactDOM.render(
  <div>
    <LocalizedModal />
    <br />
    <Button onClick={confirm}>Confirm</Button>
  </div>,
  mountNode,
);

自定义位置

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

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);

自定义页脚按钮属性

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

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 with customized button props
        </Button>
        <Modal
          title="Basic Modal"
          visible={this.state.visible}
          onOk={this.handleOk}
          onCancel={this.handleCancel}
          okButtonProps={{ disabled: true }}
          cancelButtonProps={{ disabled: true }}
        >
          <p>Some contents...</p>
          <p>Some contents...</p>
          <p>Some contents...</p>
        </Modal>
      </div>
    );
  }
}
ReactDOM.render(<App />, mountNode);

异步关闭

点击确定后异步关闭对话框，例如提交表单。

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);

确认对话框

使用 confirm() 可以快捷地弹出确认框。

import { Modal, Button } from 'antd';
const confirm = Modal.confirm;
function showConfirm() {
  confirm({
    title: 'Do you Want to delete these items?',
    content: 'Some descriptions',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
}
function showDeleteConfirm() {
  confirm({
    title: 'Are you sure delete this task?',
    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?',
    content: 'Some descriptions',
    okText: 'Yes',
    okType: 'danger',
    okButtonProps: {
      disabled: true,
    },
    cancelText: 'No',
    onOk() {
      console.log('OK');
    },
    onCancel() {
      console.log('Cancel');
    },
  });
}
ReactDOM.render(
  <div>
    <Button onClick={showConfirm}>Confirm</Button>
    <Button onClick={showDeleteConfirm} type="dashed">
      Delete
    </Button>
    <Button onClick={showPropsConfirm} type="dashed">
      With extra props
    </Button>
  </div>,
  mountNode,
);

信息提示

各种类型的信息提示，只提供一个按钮用于关闭。

import { Modal, Button } 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({
    title: 'This is a success message',
    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(
  <div>
    <Button onClick={info}>Info</Button>
    <Button onClick={success}>Success</Button>
    <Button onClick={error}>Error</Button>
    <Button onClick={warning}>Warning</Button>
  </div>,
  mountNode,
);

手动更新和移除

手动更新和关闭 Modal.method 方式创建的对话框。

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);

销毁确认对话框

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。

import { Modal, Button } from 'antd';
function destroyAll() {
  Modal.destroyAll();
}
const confirm = Modal.confirm;
function showConfirm() {
  for (let i = 0; i < 3; i += 1) {
    setTimeout(() => {
      confirm({
        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,
);

API

注意

<Modal /> 默认关闭后状态不会自动清空, 如果希望每次打开都是新内容，请设置 destroyOnClose。

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：

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();
});
