当某一个节点还没有渲染出来，但这个时候又调用了js 原生的scrollIntoView；或者这个节点已经生成，方法也成功调用，但是又被其他晚加载的元素顶掉了，导致scrollIntoView失效。这个库就是用来解决这种情况。妈妈再也不用担心scrollIntoView失效了！！！ rc-scroll-into-view.

Install

yarn add rc-scroll-into-view

or

npm install rc-scroll-into-view --save

Usage

import React, { useRef } from 'react';
import ScrollIntoView from 'rc-scroll-into-view';
const App = () => {
  const ref = useRef();
  return (
    <ScrollInto scrollRef={ref} scrollOptions={{ block: 'center', behavior: 'smooth' }}>
      <div ref={ref}>child</div>
    </ScrollInto>
  );
};
export default App;

使用 selector

import React from 'react';
import ScrollInto from 'rc-scroll-into-view';
const App = () => (
  <ScrollInto selector="#test" scrollOptions={{ block: 'center', behavior: 'smooth' }}>
    <div id="test">child</div>
  </ScrollInto>
);
export default App;

使用 ref

import React, { useRef } from 'react';
import ScrollInto from 'rc-scroll-into-view';
const App = () => {
  const ref = useRef();
  return (
    <ScrollInto scrollRef={ref} scrollOptions={{ block: 'center', behavior: 'smooth' }}>
      <div ref={ref}>child</div>
    </ScrollInto>
  );
};
export default App;

使用 target

import React, { useRef } from 'react';
import ScrollInto from 'rc-scroll-into-view';
const App = () => {
  const targetRef = useRef();
  const ref = useRef();
  return (
    <ScrollInto
      scrollRef={ref}
      target={targetRef}
      scrollOptions={{ block: 'center', behavior: 'smooth' }}
    >
      <div ref={targetRef}>
        这是另一个child
        <div ref={ref}>child</div>
      </div>
    </ScrollInto>
  );
};
export default App;
