React-router在每次转换时滚动到顶部

我有一个问题，当导航到另一个页面，它的位置将保持像之前的页面。所以它不会自动滚动到顶部。我也试过使用window。onChange路由器上的scrollTo(0,0)。我还使用了scrollBehavior来修复这个问题，但它没有工作。对此有什么建议吗?

当前回答

在router.js中，只需在router对象中添加这个函数。这个就行了。

scrollBehavior() {
        document.getElementById('app').scrollIntoView();
    },

像这样,

* * Routes.js * *

import vue from 'blah!'
import Router from 'blah!'

let router = new Router({
    mode: 'history',
    base: process.env.BASE_URL,
    scrollBehavior() {
        document.getElementById('app').scrollIntoView();
    },
    routes: [
            { url: "Solar System" },
            { url: "Milky Way" },
            { url: "Galaxy" },
    ]
});

其他回答

我写了一个叫withScrollToTop的高阶组件。这个HOC有两个标志:

onComponentWillMount -导航时是否滚动到顶部(componentWillMount) onComponentDidUpdate—是否在更新时滚动到顶部(componentDidUpdate)。该标志在组件没有卸载但发生导航事件的情况下是必要的，例如，从/users/1到/users/2。

// @flow
import type { Location } from 'react-router-dom';
import type { ComponentType } from 'react';

import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';

type Props = {
  location: Location,
};

type Options = {
  onComponentWillMount?: boolean,
  onComponentDidUpdate?: boolean,
};

const defaultOptions: Options = {
  onComponentWillMount: true,
  onComponentDidUpdate: true,
};

function scrollToTop() {
  window.scrollTo(0, 0);
}

const withScrollToTop = (WrappedComponent: ComponentType, options: Options = defaultOptions) => {
  return class withScrollToTopComponent extends Component<Props> {
    props: Props;

    componentWillMount() {
      if (options.onComponentWillMount) {
        scrollToTop();
      }
    }

    componentDidUpdate(prevProps: Props) {
      if (options.onComponentDidUpdate &&
        this.props.location.pathname !== prevProps.location.pathname) {
        scrollToTop();
      }
    }

    render() {
      return <WrappedComponent {...this.props} />;
    }
  };
};

export default (WrappedComponent: ComponentType, options?: Options) => {
  return withRouter(withScrollToTop(WrappedComponent, options));
};

使用它:

import withScrollToTop from './withScrollToTop';

function MyComponent() { ... }

export default withScrollToTop(MyComponent);

我唯一的解决方案是在每个文件中添加一行代码，例如:

import React from 'react';
const file = () => { document.body.scrollTop = 0; return( <div></div> ) }

对于react-router-dom V5，滚动到顶部

    import React, { useEffect } from 'react';
import {
    BrowserRouter as Router,
    Switch,
    Route,
    Link,
    useLocation,
    withRouter
} from 'react-router-dom'
function _ScrollToTop(props) {
    const { pathname } = useLocation();
    useEffect(() => {
        window.scrollTo(0, 0);
    }, [pathname]);
    return props.children
}
const ScrollToTop = withRouter(_ScrollToTop)
function App() {
    return (
        <div>
            <Router>
                <ScrollToTop>
                    <Header />
                     <Content />
                    <Footer />
                </ScrollToTop>
            </Router>
        </div>
    )
}

这有点老套(但很有效):我只是添加

Window. ScrollTo (0, 0);

呈现();

React挂钩2020:)

import React, { useLayoutEffect } from 'react';
import { useLocation } from 'react-router-dom';

const ScrollToTop: React.FC = () => {
  const { pathname } = useLocation();
  useLayoutEffect(() => {
    window.scrollTo(0, 0);
  }, [pathname]);

  return null;
};

export default ScrollToTop;
