添加css样式

a:link {
  text-decoration: none;
  color: #cc850a;
}

a:visited {
  text-decoration: none;
  color: #cc850a;
}

a:hover {
  text-decoration: none;
  color: #47a1ad;
}

a:active {
  text-decoration: none;
}

jsx:

<Link className="link">
  test
</Link>

css:

.link{
    text-decoration: none;
}

如果你正在使用样式化组件，你可以这样做:

import React, { Component } from 'react';
import { Link } from 'react-router-dom';
import styled from 'styled-components';


const StyledLink = styled(Link)`
    text-decoration: none;

    &:focus, &:hover, &:visited, &:link, &:active {
        text-decoration: none;
    }
`;

export default (props) => <StyledLink {...props} />;

/ / CSS

.navigation_bar > ul > li {
      list-style: none;
      display: inline;
      margin: 2%;
    }

    .link {
      text-decoration: none;
    }

.jsx

 <div className="navigation_bar">
            <ul key="nav">
              <li>
                <Link className="link" to="/">
                  Home
                </Link>
              </li>
            </ul>
          </div>

CSS解决方案也用于React

只在Link(React Router)标签中添加className/class。(最重要的部分!!在链接标签中添加ClassName，而不是其他标签。) 在css文件中添加text-decoration: none。

Nav.js

  <Link to="/" className="link" >
    Get Started
  </Link>

Nav.css

.link{
text-decoration: none;
}

<Link 
   _hover={{
      textDecoration: "none"
   }}
   >
   Logo
</Link>
