KeyboardDatePicker 背景颜色 - Javascript

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。

步骤
  1. 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";
    
  2. 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);
    
  3. 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"
          }}
        />
      );
    }
    
解释
  1. 通过 import 导入需要的依赖。
  2. 定义样式和更新主题,在 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。
  3. 在组件中引用并使用 StyledKeyboardDatePicker
结论

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"
      }}
    />
  );
}
