reactjs - 基于 prop 的动态样式组件标签

Question

我正在尝试创建一个带有样式组件的动态标签。标签通过 props 接收。

这是代码示例:

import * as React from 'react';
import styled from 'styled-components';

type ContainerProps = {
    children: React.ReactNode,
    type?: 'section' | 'div' | 'article',
}

const Container = styled.div`
  color: ${props => props.theme.primaryColor};
`;

const Icon = styled.div<ContainerProps>`
    background-color: red;
`;

const container: React.FunctionComponent<ContainerProps['children']> = ({ children, type = 'section' }: ContainerProps) => {
    return (
        <Container>
            <{ children }
        </Container>
    );
};

export default container;

我正在努力实现 <Container>标签(现在是 div)是一个基于 prop.type 的动态属性.

您可以使用 "as" polymorphic prop ，像这样:

import * as React from 'react';
import styled from 'styled-components';

type ContainerProps = {
    children: React.ReactNode,
    type?: 'section' | 'div' | 'article',
}

const Container = styled.div`
  color: ${props => props.theme.primaryColor};
`;

const Icon = styled.div<ContainerProps>`
    background-color: red;
`;

const container: React.FunctionComponent<ContainerProps['children']> = ({ children, type = 'section' }: ContainerProps) => {
    return (
        <Container as={type}>
            { children }
        </Container>
    );
};

export default container;
