下面是一种似乎可行的方法。该方法的要点是创建一个框(通过:after
伪元素),该框比用于检查的图标略小,并且具有所需的颜色作为背景色。然后将该框放在“选中”图标的后面。
import React from "react";
import { withStyles } from "@material-ui/core/styles";
import FormGroup from "@material-ui/core/FormGroup";
import FormControlLabel from "@material-ui/core/FormControlLabel";
import Checkbox from "@material-ui/core/Checkbox";
const CheckboxWithGreenCheck = withStyles({
root: {
"&$checked": {
"& .MuiIconButton-label": {
position: "relative",
zIndex: 0
},
"& .MuiIconButton-label:after": {
content: '""',
left: 4,
top: 4,
height: 15,
width: 15,
position: "absolute",
backgroundColor: "lightgreen",
zIndex: -1
}
}
},
checked: {}
})(Checkbox);
export default function CheckboxLabels() {
const [state, setState] = React.useState({
checkedA: true,
checkedB: false
});
const handleChange = name => event => {
setState({ ...state, [name]: event.target.checked });
};
return (
<FormGroup>
<FormControlLabel
control={
<CheckboxWithGreenCheck
checked={state.checkedA}
onChange={handleChange("checkedA")}
value="checkedA"
color="primary"
/>
}
label="Custom check color"
/>
</FormGroup>
);
}
一种替代方法是创建一个包含所需支票颜色的自定义图标,然后通过该checkedIcon
属性使用它,如演示中的“
自定义图标”示例中所示。
