如何在makeStyles中使用“主题"和“道具"? [英] How to use 'theme' and 'props' in makeStyles?

问题描述

如何编写makeStyles()，以便它允许我同时使用主题变量和道具?

How do I write makeStyles() so that it allows me to use both theme variables and props?

我已经尝试过了:

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对其进行调用:

And called it in the component with:

const classes = useStyles(backgroundColor);

backgroundColor是类型为CSSProperties["backgroundColor"]

但是我得到了错误:

我正在使用4.0.0-beta.1版本的材质核心和样式

推荐答案

您需要将对象而不是字符串传递给useStyles.

You need to pass an object to useStyles rather than a string.

所以代替:

const classes = useStyles(backgroundColor);

您应该拥有:

const classes = useStyles(props);

或

const classes = useStyles({backgroundColor});

然后您可以使用以下方法获得backgroundColor:

Then you can get at backgroundColor using:

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