样式化组件 React router v6

Question

const StyledNavLink = styled(NavLink)`
  text-decoration: ${(props) => {
    console.log(props.style);
    return props.style ? (isActive) => (isActive ? "underline" : "none") : "none";
  }};
  &:hover {
    text-decoration: underline;
  }
`;

export default function BasicExample() {
  return (
    <Router>
      <Navbar>
        <NavItems>
          <NavItem>
            <NavLink
              to="/"
              end={true}
              style={({ isActive }) => {
                console.log(isActive + "About");
                return { textDecoration: isActive ? "underline" : "none" };
              }}
            >
              Home
            </NavLink>
          </NavItem>
          <NavItem>
            <NavLink
              to="/about"
              style={({ isActive }) => {
                console.log(isActive + "About");
                return { textDecoration: isActive ? "underline" : "none" };
              }}
            >
              About
            </NavLink>
          </NavItem>
          <NavItem>
            <NavLink
              to="/dashboard"
              style={({ isActive }) => {
                console.log(isActive + "Dashboard");
                return { textDecoration: isActive ? "underline" : "none" };
              }}
            >
              Dashboard
            </NavLink>
          </NavItem>
        </NavItems>
      </Navbar>
      <Routes>
        <Route path="/" caseSensitive={false} element={<Home />}></Route>
        <Route path="/about" caseSensitive={false} element={<About />}></Route>
        <Route path="/dashboard" caseSensitive={false} element={<Dashboard />}></Route>
      </Routes>
    </Router>
  );
}

如何抽象出活动链接样式的逻辑来表示 StyledNavLink 样式组件，我尝试使用 StyledNavLink 代替 Navlink 但它不起作用。我不确定我可能会错过什么。如果我在 StyledNavLink 中控制台输出 props.style ，那么它始终是未定义的。

Answer 1

const StyledNavLink = styled(NavLink)`
  text-decoration: ${(props) => {
    console.log(props.style);
    return props.style ? (isActive) => (isActive ? "underline" : "none") : "none";
  }};
  &:hover {
    text-decoration: underline;
  }
 &[aria-current] {
    color: red;
  }
`;

我只需检查 aria-current 属性是否存在，现在如果我用 StyledNavLink 替换 NavLink，一切都会按预期工作

或者，如下所示，可以检查活动类是否存在

const StyledNavLink = styled(NavLink)`
    text-decoration: ${(props) => {
    console.log(props);
    return props.style ? (isActive) => (isActive ? "underline" : "none") : "none";
  }}; 
  &:hover {
    text-decoration: underline;
  }
 &[class*="active"] {
    color: red;
  }
`;
