with-layer

安装

npm i --save @kne/with-layer

概述

让类似Antd Modal的使用传送门(createPortal)创建的弹窗类的组件可以用函数的方式调用。

• 由于已经脱离原来的上下文(context)，所以弹窗内无法使用弹窗外的context，如果有些全局的context，需要在preset中设置withInstall，它是一个高阶组件
• 也可以在调用withLayer的时候传入withInstall来做context中继，它会后于preset的withInstall执行而不会覆盖

示例

示例代码

• 普通的弹窗示例
• 展示一个普通的弹窗示例
• _withLayer(@kne/with-layer),modal(antd/lib/modal),button(antd/lib/button),lodash(lodash)

const { default: withLayer } = _withLayer;
const { default: Button } = button;
const { default: Modal } = modal;
const { omit } = lodash;

const createModal = withLayer((props) => {
  const others = omit(props, ["close"]);
  return <Modal {...others}>
    我是一个弹窗<Button onClick={props.close}>关闭</Button>
  </Modal>;
});

const BaseExample = () => {
  return <Button type="primary" onClick={() => {
    const instance = createModal({
      withInstall:(WrappedComponent)=>(props)=><div className="test"><WrappedComponent {...props}/></div>,
      title: "弹窗示例"
    });
  }}>弹出弹窗</Button>;
};

render(<BaseExample />);

• context中继
• 展示context中继的方法
• _withLayer(@kne/with-layer),modal(antd/lib/modal),button(antd/lib/button),lodash(lodash)

const { default: withLayer } = _withLayer;
const { default: Button } = button;
const { default: Modal } = modal;
const { omit } = lodash;
const { createContext, useContext } = React;

const createModal = withLayer((props) => {
  const others = omit(props, ["close"]);
  const contextValue = useContext(context);
  return <Modal {...others}>
    我是一个弹窗<Button onClick={props.close}>关闭</Button>{JSON.stringify(contextValue)}
  </Modal>;
});

const context = createContext({});

const { Provider } = context;

const InnerComponent = () => {
  const contextValue = useContext(context);
  return <Button type="primary" onClick={() => {
    const instance = createModal({
      title: "弹窗示例",
      withInstall: (WrappedComponents) => (props) => <Provider
        value={contextValue}><WrappedComponents {...props} /></Provider>
    });
  }}>弹出弹窗</Button>;
};

const BaseExample = () => {
  return <Provider value={{test:123}}>
    <InnerComponent />
  </Provider>;
};

render(<BaseExample />);
