在react.js中渲染后滚动到页面顶部

我有个问题，我不知道怎么解决。在我的react组件中，我在底部显示了一个很长的数据列表和一些链接。点击任何链接后，我在列表中填充了新的链接集合，需要滚动到顶部。

问题是-如何滚动到顶部后，新的集合呈现?

'use strict';

// url of this component is #/:checklistId/:sectionId

var React = require('react'),
  Router = require('react-router'),
  sectionStore = require('./../stores/checklist-section-store');


function updateStateFromProps() {
  var self = this;
  sectionStore.getChecklistSectionContent({
    checklistId: this.getParams().checklistId,
    sectionId: this.getParams().sectionId
  }).then(function (section) {
    self.setState({
      section,
      componentReady: true
    });
  });

    this.setState({componentReady: false});
 }

var Checklist = React.createClass({
  mixins: [Router.State],

  componentWillMount: function () {
    updateStateFromProps.call(this);
  },

  componentWillReceiveProps(){
    updateStateFromProps.call(this);
   },

render: function () {
  if (this.state.componentReady) {
    return(
      <section className='checklist-section'>
        <header className='section-header'>{ this.state.section.name }   </header>
        <Steps steps={ this.state.section.steps }/>
        <a href=`#/${this.getParams().checklistId}/${this.state.section.nextSection.Id}`>
          Next Section
        </a>
      </section>
    );
    } else {...}
  }
});

module.exports = Checklist;

我在一个组件上使用了类似的方法:

<div ref="scroller" style={{height: 500, overflowX: "hidden", overflowY: "auto"}}>
      //Content Here
</div>

然后在处理更新的函数中:

this.refs.scroller.scrollTop=0

其他回答

点击后出现的页面，只需在其中写入即可。

  componentDidMount() {
    window.scrollTo(0, 0);
  }

这就是我所做的:

useEffect(() => ref.current.scrollTo(0, 0));
const ref = useRef()

       return(
         <div ref={ref}>
           ...
         </div>
        )

这段代码将导致滚动的平滑行为:

<div onClick={() => {
   ReactDOM.findDOMNode(this.headerRef)
      .scrollIntoView({behavior: "smooth"});
                }} 
  className='go-up-button' >
</div>

你可以在scrollIntoView()中传递其他参数可以使用以下语法:

element.scrollIntoView();
element.scrollIntoView(alignToTop); // Boolean parameter
element.scrollIntoView(scrollIntoViewOptions); // Object parameter

alignToTop可选为布尔值:

If true, the top of the element will be aligned to the top of the visible area of the scrollable ancestor. Corresponds to scrollIntoViewOptions: {block: "start", inline: "nearest"}. This is the default value.
If false, the bottom of the element will be aligned to the bottom of the visible area of the scrollable ancestor. Corresponds to scrollIntoViewOptions: {block: "end", inline: "nearest"}.

scrollIntoViewOptions可选是具有以下属性的对象:

*behavior* Optional
    Defines the transition animation.
    One of "auto", "instant", or "smooth". Defaults to "auto".
*block* Optional
    One of "start", "center", "end", or "nearest". Defaults to "center".
*inline* Optional
    One of "start", "center", "end", or "nearest". Defaults to "nearest".

我什么都试过了，但这是唯一有效的办法。

 useLayoutEffect(() => {
  document.getElementById("someID").scrollTo(0, 0);
 });

功能组件;

import React, {useRef} from 'react';
function ScrollingExample (props) {
// create our ref
const refToTop = useRef();

return (
<h1 ref={refToTop}> I wanna be seen </h1>
// then add enough contents to show scroll on page
<a onClick={()=>{
    setTimeout(() => { refToTop.current.scrollIntoView({ behavior: 'smooth' })}, 500)
        }}>  Take me to the element <a>
);
}
