reactjs - 在 Material-ui Autocomplete 组件上设置文本颜色、轮廓和填充

问题描述

我们想更改 Material-ui 自动完成组件上的文本颜色、轮廓和填充。

代码如下所示：

              <FormControlLabel
                label="Please enter desired service:"
                labelPlacement="start"
                control={
                  <Autocomplete
                    id="services"
                    options={props.serviceTypes}
                    getOptionLabel={option => option.name}
                    className={classes.inputRoot}
                    style={{ width: 400, paddingLeft: 20 }}
                    renderInput={params => (
                      <TextField
                        {...params}
                        label=""
                        className={classes.inputRoot}
                        variant="outlined"
                        fullWidth
                      />
                    )}
                    onChange={setService}
                  />
                }
              />

我们可以通过这样的代码更改 TextInput 颜色

                        InputProps={{
                          className: classes.inputColor
                        }}

但是以这种方式应用样式会影响自动完成功能（它会失去自动完成功能并且表现得像普通的 TextField）。

我们尝试了许多样式和类名选项都无济于事。

感谢任何建议。

解决方案

这是您尝试过的方法（就样式而言，它有效，但破坏了自动完成功能）：

renderInput={params => (
    <TextField
       {...params}
       label=""
       InputProps={{
          className: classes.inputColor
       }}
       variant="outlined"
       fullWidth
    />
)}

上述方法会导致问题，因为Autocomplete组件将 InputProps作为params传递给的一部分传递，TextField因此InputProps显式传递的将完全替换InputPropsin params。

相反，您应该将inputRoot CSS 类用于 Autocomplete 组件：

<Autocomplete classes={{inputRoot: classes.inputRoot}} .../>

下面是一个有效的 v4 示例（下方的 v5 示例），它自定义了输入和标签的文本颜色、轮廓颜色和 padding-left。

import React from "react";
import TextField from "@material-ui/core/TextField";
import Autocomplete from "@material-ui/lab/Autocomplete";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles((theme) => ({
  root: {
    "& .MuiInputLabel-outlined:not(.MuiInputLabel-shrink)": {
      // Default transform is "translate(14px, 20px) scale(1)""
      // This lines up the label with the initial cursor position in the input
      // after changing its padding-left.
      transform: "translate(34px, 20px) scale(1);"
    }
  },
  inputRoot: {
    color: "purple",
    // This matches the specificity of the default styles at https://github.com/mui-org/material-ui/blob/v4.11.3/packages/material-ui-lab/src/Autocomplete/Autocomplete.js#L90
    '&[class*="MuiOutlinedInput-root"] .MuiAutocomplete-input:first-child': {
      // Default left padding is 6px
      paddingLeft: 26
    },
    "& .MuiOutlinedInput-notchedOutline": {
      borderColor: "green"
    },
    "&:hover .MuiOutlinedInput-notchedOutline": {
      borderColor: "red"
    },
    "&.Mui-focused .MuiOutlinedInput-notchedOutline": {
      borderColor: "purple"
    }
  }
}));

export default function ComboBox() {
  const classes = useStyles();
  return (
    <Autocomplete
      id="combo-box-demo"
      classes={classes}
      options={top100Films}
      getOptionLabel={(option) => option.title}
      style={{ width: 300 }}
      renderInput={(params) => {
        return (
          <TextField
            {...params}
            label="Combo box"
            variant="outlined"
            fullWidth
          />
        );
      }}
    />
  );
}

import { styled } from "@mui/material/styles";

const StyledAutocomplete = styled(Autocomplete)({

    // Default transform is "translate(14px, 20px) scale(1)""
    // This lines up the label with the initial cursor position in the input
    // after changing its padding-left.
    transform: "translate(34px, 20px) scale(1);"
  },
  "& .MuiAutocomplete-inputRoot": {
    color: "purple",
    // This matches the specificity of the default styles at https://github.com/mui-org/material-ui/blob/v4.11.3/packages/material-ui-lab/src/Autocomplete/Autocomplete.js#L90
    '&[class*="MuiOutlinedInput-root"] .MuiAutocomplete-input:first-child': {
