我正在建立一个博客,单击链接到文章的链接后,我希望新页面在文章标题上滚动。
我尝试使用<Link to={`/${node.slug}#blog-title`}>{node.title}</Link>
但是它不会滚动到标题,而是滚动回到页面顶部。
我试图在componentDidMount中使用window.scrollTo(document.getElementById('blog-title);),但直到那时它似乎都没有被修正,并且仍然显示在顶部。如果使用setTimeout,它只会滚动到顶部立即滚动到正确的ID。
index.js
return (
<article className="blog-listing" key={node.slug}>
<div className="entry-meta-content">
<h2 className="entry-title">
<Link to={`/${node.slug}`}>{node.title}</Link>
</h2>
<span className="entry-meta">
Created on {node.publishDate} By {node.author.name}
</span>
</div>
<div className="entry-media">
<Img fluid={node.heroImage.fluid} backgroundColor="#f4f8fb" />
</div>
<div className="entry-content-bottom">
<p className="entry-content">{node.body.childMarkdownRemark.excerpt}</p>
<Link to={`/${node.slug}`} className="entry-read-more">
<span />
Read More
</Link>
</div>
</article>
);
blog-post.js
import React, { Component } from 'react';
import get from 'lodash/get';
import Helmet from 'react-helmet';
import { graphql } from 'gatsby';
import Img from 'gatsby-image';
import Template from '../components/layout';
class BlogPostTemplate extends Component {
render() {
const post = get(this, 'props.data.contentfulBlogPost');
return (
<Template>

<h1 className="section-headline"> {post.title} </h1>
<p> {post.publishDate} </p>
<div
dangerouslySetInnerHTML={{
__html: post.body.childMarkdownRemark.html
}}

</div>
</div>

</Template>

}
}
export default BlogPostTemplate;
export const pageQuery = graphql`

谢谢!

在您的blogpost.js
中,您要将一个ID附加到<Helmet>
标签上,该标签不会在正文中生成任何内容。也许您应该将其附加到正文中的标题上?
...
<Template>
- <Helmet title={`${post.title}`} id="blog-title" />
+ <Helmet title={`${post.title}`} />
<div className="inner-blog-post">
<div className="container">
<div className="row">
<div className="col-lg-12 col-md-12">
<div className="entry-media">
<Img fluid={post.heroImage.fluid} backgroundColor="#f4f8fb" />
</div>
- <h1 className="section-headline"> {post.title} </h1>
+ <h1 id="blog-title" className="section-headline"> {post.title} </h1>
