在 material-ui 中为 JSS 创建通用样式 类

Create common style classes for JSS in material-ui

我正在使用 material-ui 的 JSS 实现来设置样式 类。

当涉及到组件时,我有很多重复的代码styles,因为我已经分离了我的组件。

例如,我有一些使用通用样式的卡片:

const styles = theme => ({
  cardContainer: {
    position: 'relative',
    width: '50%',
    padding: theme.spacing.unit / 2,
  },
  cardOuter: {
    height: '100%',
    width: '100%',
    textAlign: 'start',
  },
  card: {
    width: '100%',
    background: theme.palette.backgrounds.card.off,
  },
  cardOn: {
    background: theme.palette.backgrounds.card.on,
  },
  cardUnavailable: {
    background: theme.palette.backgrounds.card.disabled,
  },
  cardContent: {
    display: 'flex',
    flexWrap: 'wrap',
    minHeight: 98,
    height: 98,
    [theme.breakpoints.down('sm')]: {
      minHeight: 74,
      height: 74,
    },
    padding: `${theme.spacing.unit * 1.5}px !important`,
  },
});

我很少想扩展组件内的样式,但想将这些对象导入现有的 styles 函数中,这样我就不必复制这些对象。

有人知道怎么做吗?

谢谢

想通了。对于未来的观众:

const styles = theme => ({
  ...card(theme),
  grid: {
    height: '100%',
    width: 'fit-content',
    paddingLeft: theme.spacing.unit * 2,
    paddingRight: theme.spacing.unit * 2,
    flexWrap: 'nowrap',
    overflowY: 'hidden',
  },
  name: {
    overflow: 'hidden',
    textOverflow: 'ellipsis',
    fontSize: '1.12rem',
    fontColor: theme.palette.text.main,
    [theme.breakpoints.down('sm')]: {
      fontSize: '0.9rem',
    }
  },
  state: {
    textOverflow: 'ellipsis',
    margin: '0 auto',
    marginTop: theme.spacing.unit / 2,
    fontSize: '1.0rem',
    fontColor: theme.palette.text.light,
    [theme.breakpoints.down('sm')]: {
      fontSize: '0.8rem',
    }
  },
  alarmArmedHome: {
    background: theme.palette.backgrounds.card.alarm.home,
  },
  alarmArmedAway: {
    background: theme.palette.backgrounds.card.alarm.away,
  },
  alarmTriggered: {
    background: theme.palette.backgrounds.card.alarm.triggered,
  },
  icon: {
    margin: '0 auto',
    color: theme.palette.text.icon,
    fontSize: '2.7rem',
    [theme.breakpoints.down('sm')]: {
      fontSize: '1.7rem',
    }
  },
});

card.js

const styles = (theme) => ({
  cardContainer: {
    position: 'relative',
    width: '50%',
    padding: theme.spacing.unit / 2,
  },
  cardOuter: {
    height: '100%',
    width: '100%',
    textAlign: 'start',
  },
  card: {
    width: '100%',
    background: theme.palette.backgrounds.card.off,
  },
  cardOn: {
    background: theme.palette.backgrounds.card.on,
  },
  cardUnavailable: {
    background: theme.palette.backgrounds.card.disabled,
  },
  cardContent: {
    display: 'flex',
    flexWrap: 'wrap',
    minHeight: 98,
    height: 98,
    [theme.breakpoints.down('sm')]: {
      minHeight: 74,
      height: 74,
    },
    padding: `${theme.spacing.unit * 1.5}px !important`,
  },
});

export default styles;

因此,如果需要,您几乎必须加入主题中传递的对象:

...card(theme),
