我在React项目中使用MaterialUI的标签。
这是选项卡的JSX:
<AppBar color="default" position="static">
<Tabs indicatorColor="primary" textColor="primary" value={tabIndex} onChange={this.handleChange}>
{instances.map(instance =>
<StyledTab
style={{ textTransform: 'initial' }}
onClick={() => { this.changeActiveInstance(instance.id) }}
label={this.getTabAddress(instance)}
icon={<ClearIcon ></ClearIcon>}
>
</StyledTab>
)}
</Tabs>
这就是我注入CSS的方式:
const StyledTab = withStyles({
root: {
textTransform: 'initial'
},
})(Tab);
我想将“ ClearIcon”放置在其他位置。我尝试过一点样式注入,但没有成功。
有人可以指出我正确的方向吗?

尝试自定义任何Material-UI组件时,起点是CSS portion of the API documentation。在这种情况下,您可能要覆盖的最相关的类是wrapper
,labelContainer
和label
。
要完全了解它们的使用方式以及默认情况下它们的样式(以及因此可能要覆盖的内容)的最好方法是查看source code。
以下是Tab.js中样式中最相关的部分:
/* Styles applied to the `icon` and `label`'s wrapper element. */
wrapper: {
display: 'inline-flex',
alignItems: 'center',
justifyContent: 'center',
width: '100%',
flexDirection: 'column',
},
/* Styles applied to the label container element if `label` is provided. */
labelContainer: {
width: '100%', // Fix an IE 11 issue
boxSizing: 'border-box',
padding: '6px 12px',
[theme.breakpoints.up('md')]: {
padding: '6px 24px',
},
},
以下是相关代码,用于了解如何使用它们:
if (labelProp !== undefined) {
label = (
<span className={classes.labelContainer}>
<span
className={classNames(classes.label, {
[classes.labelWrapped]: this.state.labelWrapped,
})}
ref={ref => {
this.labelRef = ref;
}}
>
{labelProp}
</span>
</span>
);
}
<span className={classes.wrapper}>
{icon}
{label}
</span>
下面是一些自定义方式的示例。
import React from "react";
import PropTypes from "prop-types";
import Paper from "@material-ui/core/Paper";
import { withStyles } from "@material-ui/core/styles";
import Tabs from "@material-ui/core/Tabs";
import Tab from "@material-ui/core/Tab";
import PhoneIcon from "@material-ui/icons/Phone";
import FavoriteIcon from "@material-ui/icons/Favorite";
import PersonPinIcon from "@material-ui/icons/PersonPin";
const styles = {
root: {
flexGrow: 1,
maxWidth: 700
},
firstIcon: {
paddingLeft: 70
},
labelContainer: {
width: "auto",
padding: 0
},
iconLabelWrapper: {
flexDirection: "row"
},
iconLabelWrapper2: {
flexDirection: "row-reverse"
}
};
class IconLabelTabs extends React.Component {
state = {
value: 0
};
handleChange = (event, value) => {
this.setState({ value });
};
render() {
const { classes } = this.props;
return (
<Paper square className={classes.root}>
<Tabs
value={this.state.value}
onChange={this.handleChange}
variant="fullWidth"
indicatorColor="secondary"
textColor="secondary"
>
<Tab
icon={<PhoneIcon className={classes.firstIcon} />}
label="Class On Icon"
/>
<Tab
classes={{
wrapper: classes.iconLabelWrapper,
labelContainer: classes.labelContainer
}}
icon={<FavoriteIcon />}
label="Row"
/>
<Tab
classes={{
wrapper: classes.iconLabelWrapper2,
labelContainer: classes.labelContainer
}}
icon={<PersonPinIcon />}
label="Row-Reverse"
/>
<Tab icon={<PersonPinIcon />} label="Default" />
</Tabs>
</Paper>
);
}
}
IconLabelTabs.propTypes = {
classes: PropTypes.object.isRequired
};
export default withStyles(styles)(IconLabelTabs);
