'Sync scroll react. div block with main scroll on window
I want to synchronize a divs scroll with a body scroll.
I tried some examples with two divs but I couldn't manage fix it with the body scroll.
Sample code with two divs: https://codesandbox.io/s/react-custom-scroll-sync-of-2-divs-10xpi
My Code
https://codesandbox.io/s/funny-rain-ditbv
import "./styles.css";
import { useRef } from "react";
export default function App() {
const firstDivRef = useRef();
const secondDivRef = useRef();
const handleScrollFirst = (scroll) => {
secondDivRef.current.scrollTop = scroll.target.scrollTop;
};
const handleScrollSecond = (scroll) => {
firstDivRef.current.scrollTop = scroll.target.scrollTop;
};
return (
<div
className="App"
style={{
display: "flex",
}}
>
<div
onScroll={handleScrollFirst}
ref={firstDivRef}
style={{
height: "500px",
overflow: "scroll",
backgroundColor: "#FFDAB9",
position: "sticky",
top: "0px"
}}
>
<div style={{ height: 5000, width: 300 }}>
The first div (or it can be tbody of a table and etc.)
{[...new Array(1000)].map((_, index) => {
const isEven = index % 2 === 0;
return (
<div style={{ backgroundColor: isEven ? "#FFFFE0 " : "#FFDAB9" }}>
{index}
</div>
);
})}
</div>
</div>
<div
onScroll={handleScrollSecond}
ref={secondDivRef}
style={{
height: "100%",
backgroundColor: "#EEE8AA"
}}
>
<div style={{ height: 5000, width: 200 }}>
The second div
{[...new Array(1000)].map((_, index) => {
const isEven = index % 2 === 0;
return (
<div style={{ backgroundColor: isEven ? "#FFFFE0 " : "#FFDAB9" }}>
{index}
</div>
);
})}
</div>
</div>
</div>
);
}
