单击导航栏链接时如何滚动到特定的目标组件 [英] How to scroll to a specific targeted component when clicking on Navbar Link

问题描述

我有多个组件，其中一个是导航栏中的组件，我有多个应该滚动到每个部分或组件的链接，在纯HTML中，我们使用href和anchor标签.但是在这里我找到了一个名为react-scroll的React库，但是问题是我不知道如何从Navbar组件中的Link链接到不同文件夹中的每个组件.任何帮助将不胜感激.

i have multiple components one of them is navbar component in this navbar i have multiple Link that should scroll to each section or component, in plain HTML we use href and anchor tag. but here i found a react library called react-scroll but the issue is i dont know how to link each component in defferent folders from the Link in Navbar 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="/"

                >
                  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;

这是添加了所有组件的家庭组件

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>
        );
      }
    }

推荐答案

react-scroll是一个很棒的库-让我尝试解释一下我的理解.

react-scroll is a great library - let me try and explain how I understand it.

在需要滚动到某个元素的Link的任何地方，我都会导入该链接，对其进行定义并进行渲染:

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;

在单独的文件中，我们定义Link滚动到的目标.从react-scroll导入Element使其非常容易！

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>
  )
}

有道理吗?让我知道我是否可以进一步扩展-希望这会有所帮助！

Making sense? Let me know if I can expand further - hope this helps!
