在使用 Material-UI 中的 KeyboardDatePicker 组件时,有时我们需要去修改其背景颜色以适应当前应用的主题。下面介绍如何在 Javascript 中修改 KeyboardDatePicker 组件的背景颜色。
导入组件和主题相关的依赖
import React from "react";
import { KeyboardDatePicker } from "@material-ui/pickers";
import { withStyles } from "@material-ui/styles";
定义样式和更新主题
const StyledKeyboardDatePicker = withStyles(theme => ({
root: {
width: 245,
"& .MuiInputBase-root": {
backgroundColor:
theme.palette.type === "dark" ? "#424242" : theme.palette.primary[50]
},
"& .MuiInputBase-root:hover": {
backgroundColor:
theme.palette.type === "dark" ? "#616161" : theme.palette.primary[100]
},
"& .MuiInputBase-root.Mui-focused": {
backgroundColor:
theme.palette.type === "dark" ? "#616161" : theme.palette.primary[100],
"& .MuiIconButton-root": {
color: theme.palette.type === "dark" ? "#9e9e9e" : undefined
}
},
"& .MuiOutlinedInput-notchedOutline": {
borderColor: theme.palette.type === "dark" ? "#616161" : "#e0e0e0"
}
}
}))(KeyboardDatePicker);
在组件中引用并使用
export default function App() {
const [selectedDate, handleDateChange] = React.useState(new Date());
return (
<StyledKeyboardDatePicker
margin="normal"
id="date-picker-dialog"
label="Date picker dialog"
format="MM/dd/yyyy"
value={selectedDate}
onChange={date => handleDateChange(date)}
KeyboardButtonProps={{
"aria-label": "change date"
}}
/>
);
}
import
导入需要的依赖。withStyles
方法中传入一个回调函数,该回调函数中的 theme
对象包含当前主题信息,例如颜色、宽度等。在样式中使用条件语句来根据当前主题动态设置背景颜色等。通过传入 StyledKeyboardDatePicker
读取修改后的样式。StyledKeyboardDatePicker
。通过以上步骤,在 Javascript 中轻松地修改 KeyboardDatePicker 组件的背景颜色。注意,我们在样式中设置的颜色和边框色具有可修改和可扩展性,因此可以根据需要进行定制。代码片段如下:
import React from "react";
import { KeyboardDatePicker } from "@material-ui/pickers";
import { withStyles } from "@material-ui/styles";
const StyledKeyboardDatePicker = withStyles(theme => ({
root: {
width: 245,
"& .MuiInputBase-root": {
backgroundColor:
theme.palette.type === "dark" ? "#424242" : theme.palette.primary[50]
},
"& .MuiInputBase-root:hover": {
backgroundColor:
theme.palette.type === "dark" ? "#616161" : theme.palette.primary[100]
},
"& .MuiInputBase-root.Mui-focused": {
backgroundColor:
theme.palette.type === "dark" ? "#616161" : theme.palette.primary[100],
"& .MuiIconButton-root": {
color: theme.palette.type === "dark" ? "#9e9e9e" : undefined
}
},
"& .MuiOutlinedInput-notchedOutline": {
borderColor: theme.palette.type === "dark" ? "#616161" : "#e0e0e0"
}
}
}))(KeyboardDatePicker);
export default function App() {
const [selectedDate, handleDateChange] = React.useState(new Date());
return (
<StyledKeyboardDatePicker
margin="normal"
id="date-picker-dialog"
label="Date picker dialog"
format="MM/dd/yyyy"
value={selectedDate}
onChange={date => handleDateChange(date)}
KeyboardButtonProps={{
"aria-label": "change date"
}}
/>
);
}
