反应滚动|单击导航栏链接时如何滚动到特定的目标组件 [英] react-scroll | How to scroll to a specific targeted component when clicking on Navbar Link
问题描述
我正在使用 React 制作单个滚动页面，并希望导航到页面的特定部分.在 HTML 中，我们使用 href 和锚标记来实现这种交互.
我找到了一个名为 react-scroll 的 React 库，但我不知道如何从 NavBar 组件中的 a 链接链接不同文件夹中的每个组件.我的 NavBar 有多个链接用于滚动到一个部分/组件.任何帮助将不胜感激！
import React, { Component } from "react";import { Link, animateScroll as scroll } from react-scroll";类导航栏扩展组件{使成为() {返回 (<nav className="navbar navbar-expand-lg navbar-dark"><Link className="navbar-brand";到=/">CMD <span>自定义电影数据库</span></链接><按钮className =导航栏切换器"类型=按钮"数据切换=折叠"数据目标=#navbarNav"；aria-controls="navbarNav";aria-expanded="false";aria-label="切换导航";><span className="navbar-toggler-icon";/><div className="collapse navbar-collapse";id="navbarNav"><ul className="navbar-nav"><li className="nav-item "><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>家</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>搜索</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>类别</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>受欢迎的</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>预告片</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>文章</链接><li className="nav-item"><链接className =导航链接"；到=/"间谍={真}平滑={真}偏移={-70}持续时间={500}>接触</链接></nav>);}}导出默认导航栏；
这是添加了所有组件的 Home 组件
class Home 扩展 React.Component {使成为() {返回 (<React.Fragment><导航栏/><展示/><FormWrapper/><类别列表/><电影网格/><电影预告片/><文章网格/><页脚/></React.Fragment>);}}react-scroll 是一个很棒的库 - 让我试着解释一下我是如何理解它的.
只要我需要一个滚动到某个元素的 Link，我就会导入该链接，定义它，然后渲染它:
import React, { Component } from 'react'从反应滚动"导入滚动const ScrollLink = Scroll.ScrollLink类导航栏扩展组件{使成为() {返回 (<导航><滚动链接to=示例目的地"间谍={真}平滑={真}持续时间={500}班级名称='某个班级'activeClass='some-active-class'>链接文本在这里</ScrollLink></nav>)}导出默认导航栏；
在一个单独的文件中，我们定义了 `Link` 将滚动到的目的地.来自 react-scroll 的 `Element` 导入使这变得非常简单！
import React, { Component } from 'react'从反应滚动"导入{元素}导出默认函数 () {返回 (<React.Fragment><Element id='example-destination' name='example-destination'>//将您的内容包装在 react-scroll 的 Element 中</元素></React.Fragment>)}有意义吗?如果我可以进一步扩展，请告诉我！
I am making a single scroller page using React and want to navigate to a specific section of the page. In HTML we use an href and anchor tag to achieve this interaction.
I found a React library called react-scroll but I do not know how to link each component in different folders from the a link in the NavBar component. My NavBar has multiple links for scrolling to a section/ component. Any help would really be appreciated!
import React, { Component } from "react";
import { Link, animateScroll as scroll } from "react-scroll";
class Navbar extends Component {
render() {
return (
<nav className="navbar navbar-expand-lg navbar-dark">
<Link className="navbar-brand" to="/">
CMD <span>Custom Movie Database</span>
</Link>
<button
className="navbar-toggler"
type="button"
data-toggle="collapse"
data-target="#navbarNav"
aria-controls="navbarNav"
aria-expanded="false"
aria-label="Toggle navigation"
>
<span className="navbar-toggler-icon" />
</button>
<div className="collapse navbar-collapse" id="navbarNav">
<ul className="navbar-nav">
<li className="nav-item ">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Home
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Search
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Category
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Popular
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Trailer
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Article
</Link>
</li>
<li className="nav-item">
<Link
className="nav-link"
to="/"
spy={true}
smooth={true}
offset={-70}
duration={500}
>
Contact
</Link>
</li>
</ul>
</div>
</nav>
);
}
}
export default Navbar;
This is Home Component where all component is added
class Home extends React.Component {
render() {
return (
<React.Fragment>
<Navbar />
<Showcase />
<FormWrapper />
<CategoryList />
<MovieGrid />
<MovieTrailer />
<ArticleGrid />
<Footer />
</React.Fragment>
);
}
}
react-scroll is a great library - let me try and explain how I understand it.
Wherever I need a Link that scrolls to a certain element, I import that link, define it, and render it:
import React, { Component } from 'react'
import Scroll from 'react-scroll'
const ScrollLink = Scroll.ScrollLink
class Navbar extends Component {
render() {
return (
<nav>
<ScrollLink
to="example-destination"
spy={true}
smooth={true}
duration={500}
className='some-class'
activeClass='some-active-class'
>
Link Text Goes Here
</ScrollLink>
</nav>
)
}
export default Navbar;
In a separate file, we define the destination that the `Link` will scroll to. The `Element` import from react-scroll makes this pretty easy!
import React, { Component } from 'react'
import { Element } from 'react-scroll'
export default function () {
return (
<React.Fragment>
<Element id='example-destination' name='example-destination'>
// wrap your content in the Element from react-scroll
</Element>
</React.Fragment>
)
}
Making sense? Let me know if I can expand on this further!
