更改 Material-UI TextField 上的边框颜色 [英] Change border color on Material-UI TextField

问题描述

这应该很简单，但由于某种原因，我不知道如何更改 TextField 上的边框颜色

<TextField style={{ borderColor: 'white', width: '100px' }} variant="outlined"/>

它基本上只是从文档中复制的，轮廓上的地方是白色的，所以我不知道是什么让我最后搞砸了.

我试图在 jsfiddle 或其他东西上重现，但找不到允许我导入 TextField 模块的一个

解决方案

下面是一个 v4 示例(v5 示例进一步向下)，说明如何覆盖 TextField.这显示使用三种不同的颜色:一种用于默认(绿色)，一种用于悬停(红色)，另一种用于输入具有焦点时的颜色(紫色).

从反应"导入反应；从react-dom"导入 ReactDOM；从@material-ui/core/TextField"导入TextField；从@material-ui/core/styles"导入{makeStyles}；const useStyles = makeStyles({根: {& &.MuiOutlinedInput-root .MuiOutlinedInput-notchedOutline":{边框颜色:绿色"},&:hover .MuiOutlinedInput-root .MuiOutlinedInput-notchedOutline":{边框颜色:红色"},& &.MuiOutlinedInput-root.Mui-focused .MuiOutlinedInput-notchedOutline":{边框颜色:紫色"},& &.MuiOutlinedInput-input":{颜色:绿色"},&:hover .MuiOutlinedInput-input":{颜色:红色"},& &.MuiOutlinedInput-root.Mui-focused .MuiOutlinedInput-input":{颜色:紫色"},& &.MuiInputLabel-outlined":{颜色:绿色"},&:hover .MuiInputLabel-outlined":{颜色:红色"},& &.MuiInputLabel-outlined.Mui-focused":{颜色:紫色"}}});功能应用(){const 类 = useStyles();返回 (
<文本字段className={classes.root}defaultValue=我的默认值"变体=概述"标签=我的标签"/>
);}const rootElement = document.getElementById(root");ReactDOM.render(, rootElement);

以下是使用 MUI v5 的类似示例.这使用 styled 而不是 makeStyles 并利用更类型安全的方式(在 v5 中添加)来引用全局类名(例如 .${outlinedInputClasses.root})，但继续硬编码全局类名称(例如 .MuiOutlinedInput-root)仍然可以正常工作(硬编码时语法更简单，但对拼写错误的保护较少并且没有自动完成帮助).

从反应"导入反应；从react-dom"导入 ReactDOM；从@mui/material/TextField"导入TextField；从@mui/material/OutlinedInput"导入{轮廓输入类}；import { inputLabelClasses } from "@mui/material/InputLabel";import { styled } from "@mui/material/styles";const StyledTextField = styled(TextField)({[`&.${outlinedInputClasses.root} .${outlinedInputClasses.notchedOutline}`]:{边框颜色:绿色"},[`&:hover .${outlinedInputClasses.root} .${outlinedInputClasses.notchedOutline}`]:{边框颜色:红色"},[`&.${outlinedInputClasses.root}.${outlinedInputClasses.focused} .${outlinedInputClasses.notchedOutline}`]:{边框颜色:紫色"},[`&.${outlinedInputClasses.input}`]: {颜色:绿色"},[`&:hover .${outlinedInputClasses.input}`]: {颜色:红色"},[`&.${outlinedInputClasses.root}.${outlinedInputClasses.focused} .${outlinedInputClasses.input}`]:{颜色:紫色"},[`&.${inputLabelClasses.outlined}`]:{颜色:绿色"},[`&:hover .${inputLabelClasses.outlined}`]: {颜色:红色"},[`&.${inputLabelClasses.outlined}.${inputLabelClasses.focused}`]:{颜色:紫色"}});功能应用(){返回 (
<StyledTextFielddefaultValue=我的默认值"变体=概述"标签=我的标签"/>
);}const rootElement = document.getElementById(root");ReactDOM.render(, rootElement);

This should be simple but for some reason I can't figure out how to change the border color on a TextField

<TextField style={{ borderColor: 'white', width: '100px' }} variant="outlined" />

It's basically just copied from the docs, where on the outline is white, so I can't figure out what might be messing this up on my end.

I tried to reproduce on jsfiddle or something but couldn't find one that would allow me to import the TextField module

解决方案

Below is a v4 example (v5 example further down) of how to override the color of the outline, label, and input text on the outlined variant of TextField. This shows using three different colors: one for the default (green), one for hover (red), and a different one when the input has focus (purple).

import React from "react";
import ReactDOM from "react-dom";

import TextField from "@material-ui/core/TextField";
import { makeStyles } from "@material-ui/core/styles";

const useStyles = makeStyles({
  root: {
    "& .MuiOutlinedInput-root .MuiOutlinedInput-notchedOutline": {
      borderColor: "green"
    },
    "&:hover .MuiOutlinedInput-root .MuiOutlinedInput-notchedOutline": {
      borderColor: "red"
    },
    "& .MuiOutlinedInput-root.Mui-focused .MuiOutlinedInput-notchedOutline": {
      borderColor: "purple"
    },
    "& .MuiOutlinedInput-input": {
      color: "green"
    },
    "&:hover .MuiOutlinedInput-input": {
      color: "red"
    },
    "& .MuiOutlinedInput-root.Mui-focused .MuiOutlinedInput-input": {
      color: "purple"
    },
    "& .MuiInputLabel-outlined": {
      color: "green"
    },
    "&:hover .MuiInputLabel-outlined": {
      color: "red"
    },
    "& .MuiInputLabel-outlined.Mui-focused": {
      color: "purple"
    }
  }
});

function App() {
  const classes = useStyles();
  return (
    <div className="App">
      <TextField
        className={classes.root}
        defaultValue="My Default Value"
        variant="outlined"
        label="My Label"
      />
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Below is a similar example using v5 of MUI. This uses styled instead of makeStyles and leverages a more type-safe manner (added in v5) for referencing the global class names (e.g. .${outlinedInputClasses.root}), but continuing to hard-code the global class names (e.g. .MuiOutlinedInput-root) still works fine as well (it's simpler syntax when hard-coded, but less protection from typos and no autocomplete help).

import React from "react";
import ReactDOM from "react-dom";

import TextField from "@mui/material/TextField";
import { outlinedInputClasses } from "@mui/material/OutlinedInput";
import { inputLabelClasses } from "@mui/material/InputLabel";
import { styled } from "@mui/material/styles";

const StyledTextField = styled(TextField)({
  [`& .${outlinedInputClasses.root} .${outlinedInputClasses.notchedOutline}`]: {
    borderColor: "green"
  },
  [`&:hover .${outlinedInputClasses.root} .${outlinedInputClasses.notchedOutline}`]: {
    borderColor: "red"
  },
  [`& .${outlinedInputClasses.root}.${outlinedInputClasses.focused} .${outlinedInputClasses.notchedOutline}`]: {
    borderColor: "purple"
  },
  [`& .${outlinedInputClasses.input}`]: {
    color: "green"
  },
  [`&:hover .${outlinedInputClasses.input}`]: {
    color: "red"
  },
  [`& .${outlinedInputClasses.root}.${outlinedInputClasses.focused} .${outlinedInputClasses.input}`]: {
    color: "purple"
  },
  [`& .${inputLabelClasses.outlined}`]: {
    color: "green"
  },
  [`&:hover .${inputLabelClasses.outlined}`]: {
    color: "red"
  },
  [`& .${inputLabelClasses.outlined}.${inputLabelClasses.focused}`]: {
    color: "purple"
  }
});

function App() {
  return (
    <div className="App">
      <StyledTextField
        defaultValue="My Default Value"
        variant="outlined"
        label="My Label"
      />
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
