我有三个组件,叫做blog卡片,用图片和文本呈现。根据文本的长度,卡片有不同的高度。我想呈现它们,然后得到最高的一个,再重新呈现它们,这样它们都是相同的高度。
这里是页面
import * as React from 'react'
import { SocialIconRow } from '@/components/social-icons'
import BlogPostCard from '@/components/BlogCard'
import Image from 'next/image'
import { useState, useEffect } from 'react'
import { FixedSizeList } from 'react-window'
function BlogPostCardsList({ cards }) {
const tallestCardHeight = useMemo(() => {
return Math.max(...cards.map(card => card.height))
}, [cards])
return (
<FixedSizeList
itemCount={cards.length}
itemSize={tallestCardHeight}
width={'100%'}
height={'100%'}
>
{({ index, style }) => <BlogPostCard style={style} {...cards[index]} />}
</FixedSizeList>
)
}
export default function MyComponent(props) {
const [cardHeight, setCardHeight] = useState(null);
const [maxHeight, setMaxHeight] = useState(0);
useEffect(() => {
const calculateHeight = () => {
const cards = document.querySelectorAll('.blog-post-card');
let heights = [];
cards.forEach(card => {
heights.push(card.clientHeight);
});
setMaxHeight(Math.max(...heights));
}
calculateHeight();
setCardHeight(maxHeight);
}, []);
return (

</div>
<div className="mt-4">

</div>
</div>
<div className="mt-8">
<div className="text-3xl font-bold">Featured Blogs</div>
<div className="grid grid-cols-3 gap-4 h-full mt-4 align-items-stretch">
<div style={{height: cardHeight}}>
<BlogPostCard

slug="the-hydra-protocol-family-scaling-and-network-optimization-for-the-cardano-blockchain"
imageslug="/images/hydra.png"
className="blog-post-card"
/>
</div>
<div style={{height: cardHeight}}>
<BlogPostCard
title="Ouroboros, A deep dive for non PhDs"
slug="ouroboros-a-deep-dive-for-non-phd"
imageslug="/images/ourobouros.png"
className="blog-post-card"
/>
</div>
<div className="h-full row-auto" style={{height: cardHeight}}>
<BlogPostCard
title="Ouroboros, A deep dive for non PhDs"
slug="ouroboros-a-deep-dive-for-non-phd"
imageslug="/images/ourobouros.png"
className="blog-post-card"
/>
</div>
</div>
</div>
</div>
</>
)
}
下面是卡组件:
import React from 'react'
import Link from 'next/link'
import Image from 'next/image'
function BlogPostCard(props) {
const { title, slug, imageslug } = props
return (
<Link href={`/blog/${slug}`}>
<a className="block flex flex-col justify-between rounded-md border-2 border-teal-400 transition-all duration-300 ease-in-out hover:scale-105 hover:shadow-lg">
<img className="rounded-t-md h-48 w-full object-cover" src={imageslug} alt="blog post cover" />
<span className="text-white text-2xl p-4">{title}</span>
</a>
</Link>
)
}
export default BlogPostCard
我试着动态渲染它们,然后设置它们,顺便说一句,我真的不知道我在那里做什么。

实际上,除了一个类之外,所有的类都已经完全用CSS来完成了。只需将
h-full
添加到BlogPostCard
组件的Link
内的a
标记中。然后,您就可以删除所有的JS。可选地,您还可以删除justify-between
或将其更改为justify-stretch
,以便博客文章的标题直接位于文章封面图像的下方。在下面的演示中,你可以点击run code snippet来查看结果。另外,如果你要升级到NextJS 13,值得注意的是你不再需要(事实上也不能有)
a
标签作为Link
的子标签。我建议像我下面所做的那样使用article
,无论如何,这在语义上会更正确。
