我正在尝试为下一个.js/tailwindcss应用创建头组件。导航活动类只有在第二次点击时才显示活动。我希望它在第一次点击时是活动的。我哪里出错了?我应该用tailwindcss指向什么元素来反映活动状态?
navlink.js文件:
import Link from 'next/link';
const NavItem = ({ text, href, active }) => {
return (
<Link href={href}>
<a
className={`nav__item ${
active ? 'active underline underline-offset-8' : ''
}`}
>
{text}
</a>
</Link>
);
};
export default NavItem;
标题. js:
import Image from 'next/image';
import React, { useState } from 'react';
import NavItem from './NavItem';
const MENU_LIST = [
{ text: 'About', href: '/about' },
{ text: 'My Work', href: '/MyWork' },
{ text: 'Blog', href: '/blog' },
{ text: 'Contact', href: '/contact' },
];
const Header = () => {
const [navActive, setNavActive] = useState(null);
const [activeIdx, setActiveIdx] = useState(-1);
return (
<header className="bg-white">
<nav className="max-w-5xl mx-auto border border-top-gray">
{/*containment div*/}
<div className="flex justify-between">
{/*Logo Container*/}
<div className="cursor-pointer">
<a href="/">
<Image
src="/../public/images/soulLogo.webp"
alt="site logo"
width={233}
height={144}
/>
</a>
</div>
{/*Link Container*/}
<div className="hidden md:flex">
<div
onClick={() => setNavActive(!navActive)}
className={`nav__menu-bar md:underline underline-offset-8 decoration-black `}
></div>
<div
className={`${
navActive
? 'active underline underline-offset-8 decoration-black'
: ''
} nav__menu-list flex items-center space-x-8 text-gray-700 tracking-wider `}
>
{MENU_LIST.map((menu, idx) => (
<div
onClick={() => {
setActiveIdx(idx);
setNavActive(false);
}}
key={menu.text}
>
<NavItem active={activeIdx === idx} {...menu} />
</div>
))}
</div>
</div>
{/*Mobile Menu button*/}
<div className="flex relative flex-col gap-y-2 cursor-pointer pt-14 pr-3 md:hidden">
<div className="w-24 h-1 bg-black shadow-gray-700 rounded"></div>
<div className="w-24 h-1 bg-black shadow-gray-700 rounded"></div>
<div className="w-24 h-1 bg-black shadow-gray-700 rounded"></div>
</div>
{/*Mobile Menu*/}
<
</div>
</nav>
</header>
);
};
export default Header;

我想我们使用了相同的代码,遇到了相同的问题。
我通过使用 next/router 并比较NavItem.js组件内部的路径来修复它。
navitem.js
navbar.js
