“主题”类型中不存在属性“navHeight”？将 MUI v5 语法与 Typescript 和自定义 props theme.ts 文件结合使用

Question

使用

theme.palette.primary.main

有效，但是当我尝试将 MUI 与 theme.ts 文件内的接口中声明的新道具一起使用时（MUI 文档推荐），我从发布的问题中收到错误。除了我尝试过的一切（导入接口、MUI v4 语法等）之外，我不知道还能做什么。这是我的代码：

import {styled} from "@mui/material/styles";
import {Box, Container, Grid, NativeSelect} from "@mui/material";
//import CustomLink from "../custom-link/custom-link.component";

export const Background = styled(Box)(({ theme }) => ({
  position: "fixed",
  zIndex: "10",
  height: theme.navHeight,
  width: "100%",
  backgroundColor: theme.palette.primary.main,
  boxShadow: "0 7px 4px -2px rgba(0, 0, 0, 0.1)",
}));

我的主题组件：

import React from "react";
import {ThemeProvider} from "@mui/material/styles";
import useMediaQuery from "@mui/material/useMediaQuery";
import theme from ".";

interface ThemeProps {
  children: JSX.Element | JSX.Element[];
}

function Theme({children}: ThemeProps): JSX.Element {
  const isMd = useMediaQuery(theme.breakpoints.up("md"), {
    defaultMatches: true,
  });

  let navHeight = theme.navHeightDesktop;
  let sectionPadding = theme.sectionPadding;

  if (isMd) {
    sectionPadding = "padding-bottom: 5rem;";
  } else {
    navHeight = theme.navHeightMobile;
  }

  return (
    <ThemeProvider theme={{...theme, navHeight, sectionPadding}}>
      {children}
    </ThemeProvider>
  );
}

export default Theme;

我的 theme.ts 文件：

import {createTheme} from "@mui/material/styles";

declare module "@mui/material/styles" {
  interface Theme {
    navHeightDesktop: string;
    navHeightMobile: string;
    sectionPadding: string;
    fonts: object;
    layout: object;
    tertiary?: {
      main: React.CSSProperties["color"];
    };
  }

  interface ThemeOptions {
    navHeightDesktop: string;
    navHeightMobile: string;
    sectionPadding: string;
    fonts: object;
    layout: object;
    tertiary?: {
      main: React.CSSProperties["color"];
    };
  }
}

const theme = createTheme({
  navHeightDesktop: "80px",
  navHeightMobile: "50px",
  sectionPadding: "padding-bottom: 2.5em;",
  fonts: {
    primary: "Roboto, sans-serif",
    secondary: "Roboto, sans-serif",
  },

    contentWidth: 1236,

  palette: {

      // contrastText: "rgba(0, 0, 0, 0.87)",
      main: "#fff",
      light: "#FAFAFA",
    },

export default theme;

Answer 1

这是因为

navHeight

没有在

Theme

接口中定义，使用以下代码应该可以工作

declare module "@mui/material/styles" {
  interface Theme {
    navHeight: string;
    navHeightDesktop: string;
    navHeightMobile: string;
    sectionPadding: string;
    fonts: object;
    layout: object;
    tertiary?: {
      main: React.CSSProperties["color"];
    };
  }
}
