reactjs - 使用样式化组件时如何保留原始 html 元素的属性？

Question

我发现自己处于当前情况，我有我的 Print组件是我的设计系统的基本构建 block ，并将 css 设置为一些规范化样式，这里是输入示例

InputPrint.tsx

import styled from 'styled-components';
import theme from '../util/theme';

/**
 * Styles
 */
const InputPrint = styled.input`
  display: inline-block;
  appearance: none;
`;

export default InputPrint;

然后我使用这个 Print在我的实际组件中

输入.tsx

import React from 'react';
import styled from 'styled-components';
import InputPrint from '../blueprints/InputPrint';

/**
 * Styles
 */
const StyledInput = styled(InputPrint)`
  width: 65vw;
  color: #797155;
`;

/**
 * Component
 */
function Input({ ...props }) {
  return (
    <StyledInput
      autoComplete="off"
      autoCorrect="off"
      autoCapitalize="off"
      spellCheck={false}
      {...props}
    />
  );
}

export default Input;

这里的问题发生在 props 上，在某些组件中我可能有额外的 props 或如上所述覆盖默认的 props，但仍然想传递它们所有有效的 <input />元素 Prop 。我尝试了 2 种输入方法，即

props: React.ComponentProps<typeof InputPrint>

如果我这样做 ^ 当我使用我的 <Input /> 时，我不会在 props 上获得任何自动完成功能

props: React.HTMLProps<HTMLInputElement>

如果我这样做 ^ 我会在 Input.tsx 中得到下面突出显示的 typescript 错误对于 <StyledInput />

const StyledInput: StyledComponent<"input", any, {}, never> Styles

我像这样导出默认样式的组件:

import styled from 'styled-components'
import React, { forwardRef } from 'react'

interface Props extends React.ComponentPropsWithoutRef<'input'> {
  err?: boolean
  maxWidth?: string
}

const Input = forwardRef<HTMLInputElement, Props>((props, ref) => {
  return <StyledInput ref={ref} {...props} />
})


const StyledInput = styled.input<Props>`
  margin: 5px;
  background-color: ${({ theme, type }): string => (type === 'color' ? 'transparent' : theme.secondaryColor)};
  color: ${({ theme }): string => theme.textColor};
  max-width: calc(${({ maxWidth }): string => maxWidth || '100%'} - ${defPadding * 2}px);
  width: 100%;
  text-align: center;
`

Input.displayName = 'Input'

export { Input }

然后按照我的意愿使用它或覆盖它的默认样式

import React from 'react'
import styled from 'styled-components'
import {Input} from '@frontend'

    export default function App() {
      return (
         <Input type="submit" value="Submit" err={true} />
         <RestyledRedInput type="submit" value="Submit" />
      )
    }

    // you can restyle it because of forward ref
    const RestyledRedInput = styled(Input)`
      background-color: red;
    `

对于主题，我建议您使用上下文:

import React, { useState, useEffect } from 'react'
import { clone } from 'global'
import { defaultGeneralTheme } from '../data/defaultGeneralTheme'
import { ThemeProvider, createGlobalStyle } from 'styled-components'

export const ThemeContext = React.createContext(null)
export const ThemeContextProvider = props => {
  const [generalTheme, setGeneralTheme] = useState(clone(defaultGeneralTheme))
  const [theme, setTheme] = useState(currentTheme())
  const [isDay, setIsDay] = useState(isItDay())

  useEffect(() => {
    setTheme(currentTheme())
    setIsDay(isItDay())
  }, [generalTheme])

  function currentTheme() {
    return generalTheme.isDay ? generalTheme.day : generalTheme.night
  }

  function isItDay() {
    return generalTheme.isDay ? true : false
  }

  return (
    <ThemeContext.Provider value={{ theme, generalTheme, setGeneralTheme, isDay }}>
      <ThemeProvider theme={theme}>
        <>
          <GlobalStyle />
          {props.children}
        </>
      </ThemeProvider>
    </ThemeContext.Provider>
  )
}

const GlobalStyle = createGlobalStyle`
  /* Global */
  html {
    word-break: break-word;
  }
  body {  
    line-height: 1.2rem;
    background-color: ${({ theme }) => theme.secondaryColor};
  }
`
