有没有办法在运行时更新 Material UI 主题调色板的主要颜色和次要颜色?
Is there a way to update Material UI theme palette primary and secondary color at runtime?
我们的应用程序中有一组默认的主题调色板颜色,但是出于白色标签的目的,我从 API 中获取主题主色和辅助色。在收到 API?
的值后,有什么方法可以在运行时更新这些颜色
我在应用级别包装 MUI themeProvider
import { ThemeProvider, StylesProvider } from '@material-ui/styles';
import { createMuiTheme } from '@material-ui/core';
const App = () => {
const customTheme = createMuiTheme({
palette: {
primary: {
main: "#fff0c9",
},
secondary: {
main: '#FF8200',
}
});
return(
<ThemeProvider theme={customTheme}>
<div> Component </div>
</ThemeProvider>)
}

加载组件后,API 调用会接收每个客户端更新的主要颜色和次要颜色。有没有办法在运行时更新它?
您可以在状态中存储所需的颜色并使用新颜色更新该状态。然后,您在 createMuiTheme()
中使用该状态来设置主要颜色和次要颜色。您可能还想使用 React.memo()
.
下面是设置随机颜色的示例:
const { useMemo, useState } = React;
const {
AppBar,
Button,
createMuiTheme,
CssBaseline,
ThemeProvider,
Toolbar
} = MaterialUI;
const randomColor = () =>
`#${Math.floor(Math.random() * 16777215).toString(16)}`;
const App = () => {
const [primary, setPrimary] = useState(randomColor);
const theme = useMemo(
() =>
createMuiTheme({
palette: {
primary: { main: primary }
}
}),
[primary]
);
const setRandomPrimary = () => setPrimary(randomColor);
return (
<ThemeProvider theme={theme}>
<CssBaseline />
<AppBar color="primary">
<Toolbar />
</AppBar>
<Toolbar />
<Button onClick={setRandomPrimary}>Change Color</Button>
</ThemeProvider>
);
}
ReactDOM.render(<App />, document.body);
