    javascript - Scroll to a specific div on a new page using react router dom - Stack Overflow

    programmeradmin7浏览0评论

    I am currently using react router dom for routing in my react application. I am trying to scroll to specific div on another page using Link from react router dom. The issue I am running into is that the page changes yet it does not scroll to the id of the div i have specified. I am unsure of what I am missing.

    my code is as follows: App.js

    import { Switch, Route, BrowserRouter as Router } from "react-router-dom";

import Home from "./Home";
import PageTwo from "./PageTwo";
import "./styles.css";
function App() {
  return (
    <Router>
      <div className="App">
        <Switch>
          <Route exact path="/" ponent={Home} />
          <Route path="/pagetwo" ponent={PageTwo} />
        </Switch>
      </div>
    </Router>
  );
}

export default App;

Home Page

    import { Link } from "react-router-dom";

const Home = () => {
  return (
    <div>
      <div>Navigate to div on new page</div>
      <Link to="/pagetwo#div">Home</Link>
    </div>
  );
};

export default Home;

    PageTwo:

    const PageTwo = () => {
  return (
    <div>
      <div style={{ marginTop: 500 }} id="div">
        Page Two Div
      </div>
    </div>
  );
};

export default PageTwo;

    css:

    html {
  scroll-behavior: smooth;
}

    • And where is the code that's suppose to do scrolling? – Nadia Chibrikova Commented Feb 20, 2021 at 22:18
    • if I were to type the id of the div I want to scroll to in the url next to the route it would take me to that exact div, for some reason when i use link or navlink etc from react router dom it doesn't work – Rob Terrell Commented Feb 20, 2021 at 22:20

    As of this issue on github use react-router-hash-link package.

    <HashLink to="/pagetwo#div">Home</HashLink>

    here is the codesandbox

    1. First install

    npm i react-router-hash-link

    or

    npm i react-router-hash-link --force

    2. Then import it and Provide the exact path and id of the ponent.

    import { HashLink } from 'react-router-hash-link';

<HashLink to="/some/path#with-hash-fragment">Link to Hash Fragment</HashLink>

    Note: For smmoth scroll add the following.

    <HashLink smooth to="/path#hash">
  Link to Hash Fragment
</HashLink>;

    Help: react-router-hash-link

    Not sure if someone would still e searching for it but we can just use the normal anchor as well instead of installing the above.

    <a href="#idToTag'>Tag</a>
