的方法有多种。以下是其中几种常用的方法:
import React, { useEffect } from 'react';
const MyComponent = () => {
useEffect(() => {
const handleScroll = () => {
const scrollPosition = window.innerHeight + window.scrollY;
const documentHeight = document.documentElement.offsetHeight;
if (scrollPosition >= documentHeight) {
// 到达页面底部,执行相应的逻辑操作
}
};
window.addEventListener('scroll', handleScroll);
return () => {
window.removeEventListener('scroll', handleScroll);
};
}, []);
return <div>My Component</div>;
};
import React from 'react';
import ScrollUpButton from 'react-scroll-up-button';
const MyComponent = () => {
return (
<div>
My Component
<ScrollUpButton />
</div>
);
};
import React, { useEffect, useRef } from 'react';
const MyComponent = () => {
const bottomRef = useRef(null);
useEffect(() => {
const observer = new IntersectionObserver((entries) => {
if (entries[0].isIntersecting) {
// 到达页面底部,执行相应的逻辑操作
}
});
observer.observe(bottomRef.current);
return () => {
observer.unobserve(bottomRef.current);
};
}, []);
return (
<div>
My Component
<div ref={bottomRef}></div>
</div>
);
};
以上是几种常用的方法,根据具体需求和项目情况选择适合的方法来实现在Scroll到达结束时获取ReactJs函数组件的操作。
