javascript - Material UI – 全局复选框焦点样式(不是本地)

Question

尝试使用 Material-UI (react) 在全局级别上聚焦时更改复选框的样式。

目前只有默认和悬停样式有效:

MuiCheckbox: {
  colorSecondary: {
    color: 'green',
    '&:hover': {
      color: 'blue !important',
      border: '1px solid rgba(0,0,0,0.54)',
      outline: '2px auto rgba(19,124,189,.6)'
    }
  },
}

我正在尝试做的事情，但不起作用:

MuiCheckbox: {
  colorSecondary: {
    '&$focused': {
      color: 'blue',
      border: '1px solid rgba(0,0,0,0.54)',
      outline: '2px auto rgba(19,124,189,.6)'
    },
    '&$focusVisible': {
      color: 'blue',
      border: '1px solid rgba(0,0,0,0.54)',
      outline: '2px auto rgba(19,124,189,.6)'
    },
  }
}

下面的示例显示了控制复选框的一系列可能状态的颜色。 Material-UI 不管理 Checkbox 的 focused 状态，仅管理 focusVisible 状态，因此将焦点移至 Checkbox 通过键盘将触发该状态。我通过使用 onFocus 和 onBlur 显式管理 focused 状态，在下面的示例中展示了 focused 样式复选框的属性。

import React from "react";
import ReactDOM from "react-dom";

import { createMuiTheme, ThemeProvider } from "@material-ui/core/styles";
import Checkbox from "@material-ui/core/Checkbox";

const theme = createMuiTheme({
  overrides: {
    MuiCheckbox: {
      colorSecondary: {
        color: "green",
        "&:hover": {
          color: "blue"
        },
        "&$checked": {
          color: "purple",
          "&:hover": {
            color: "lightblue"
          },
          "&.Mui-focusVisible": {
            color: "red"
          }
        },
        "&.Mui-focusVisible": {
          color: "orange"
        },
        "&.focused:not(.Mui-focusVisible):not($checked)": {
          color: "pink"
        }
      }
    }
  }
});
function App() {
  const [focused, setFocused] = React.useState(false);
  return (
    <ThemeProvider theme={theme}>
      <div className="App">
        <Checkbox
          className={focused ? "focused" : ""}
          onFocus={() => setFocused(true)}
          onBlur={() => setFocused(false)}
        />
        <input value="somewhere to move focus" />
      </div>
    </ThemeProvider>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
