【问题标题】:How do I use Rellax.js with React?如何在 React 中使用 Relax.js?
【发布时间】:2020-09-05 03:15:20
【问题描述】:
我正在尝试将 Relax.js 与 React 一起使用,但无法理解如何使用它。我只能找到https://www.npmjs.com/package/rellax#target-node。在那个链接中,他们给出了这个代码。
<div ref={ref => { this.rellaxRef = ref }}>
I’m that default chill speed of "-2"
</div>
var rellax = new Rellax(this.rellaxRef)
我如何使用带有 React 钩子的代码以及整个组件的外观。这是一个非常狭隘的组件视图。

【解决方案1】:
你可以像这样使用它WITH HOOKS:
import React, { useRef, useEffect } from "react";
import Rellax from "rellax";
export default function App() {
const rellaxRef = useRef();
useEffect(() => {
new Rellax(".animate", { // <---- Via class name
speed: -10,
center: false,
wrapper: null,
round: true,
vertical: true,
horizontal: false
});
new Rellax(rellaxRef.current, { // <---- Via useRef element
speed: -10,
center: false,
wrapper: null,
round: true,
vertical: true,
horizontal: false
});
}, []);
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<div ref={rellaxRef}>
Lorem Ipsum is simply dummy text of the printing and typesetting
</div>
<div className="animate">I’m that default chill speed of "-2"</div>
</div>
);
}
