如何在makeStyles中使用“主题”和“道具”？

Question

我该如何编写makeStyles()以便它可以同时使用主题变量和道具？

我已经试过了：

const useStyles = makeStyles(theme => ({
  appbar: props => ({
    boxShadow: "none",
    background: "transparent",
    marginTop: theme.spacing(2),
    marginBottom: theme.spacing(2),
    color: theme.palette.getContrastText(props)
  }),
}));

并在组件中使用以下命令调用它：

const classes = useStyles(backgroundColor);

backgroundColor类型在组件上的支撑在哪里CSSProperties["backgroundColor"]

但是我得到了错误：

编辑：我正在使用材料核心和样式的版本4.0.0-beta.1

Answer 1

您需要将对象传递给useStyles而不是字符串。

所以而不是：

const classes = useStyles(backgroundColor);

你应该有：

const classes = useStyles(props);

或者

const classes = useStyles({backgroundColor});

然后您可以使用以下方法获取 backgroundColor：

color: theme.palette.getContrastText(props.backgroundColor).

这是一个工作示例：https : //codesandbox.io/s/o7xryjnmly

经过测试：

"@material-ui/core": "^4.0.0-beta.1",
"@material-ui/styles": "^4.0.0-rc.0",

JavaScript示例：

my-component.js

import React from 'react';
import { makeStyles } from '@material-ui/styles';

import { useStyles } from './my-component.styles.js'; 

const myComponent = (props) => {
    const styleProps = { width: '100px', height: '100px' };
    const classes = useStyles(styleProps);

    return (
        <div className={classes.mySelector}></div> // with 100px and height 100px will be applied
    )
}

my-component.styles.js

export const useStyles = makeStyles(theme => ({
    mySelector: props => ({
        display: 'block',
        width: props.width,
        height: props.height,
    }),
}));

TypeScript示例：

我的component.ts

import React, { FC } from 'react; 
import { makeStyles } from '@material-ui/styles';

import { useStyles } from './my-component.styles.ts'; 
import { MyComponentProps, StylesProps } from './my-component.interfaces.ts'; 

const myComponent: FC<MyComponentProps> = (props) => {
    const styleProps: StylesProps = { width: '100px', height: '100px' };
    const classes = useStyles(styleProps);

    return (
        <div className={classes.mySelector}></div> // with 100px and height 100px will be applied
    )
}

my-component.interfaces.ts

export interface StyleProps {
    width: string;
    height: string;
}

export interface MyComponentProps {
}

my-component.styles.ts

import { Theme } from '@material-ui/core';
import { makeStyles } from '@material-ui/styles';

import { StyleProps } from './my-components.interfaces.ts';

export const useStyles = makeStyles<Theme, StyleProps>((theme: Theme) => ({
    mySelector: props => ({ // props = { width: string; height: string }
        display: 'block',
        width: props.width,
        height: props.height,
    }),
}));
