我正在使用来自 react-bootstrap 的 Navbar 和 Nav。当我点击汉堡包时,我想防止下拉菜单打开时身体滚动。
我曾尝试使用 body-scroll-lock 但很难发现将哪个元素设置为 targetElement 以及在哪里调用 Navbar 组件中的 showtargetElement 和 hideTargetElement 函数。
import React, { Component } from 'react';
import { Navbar, Nav } from 'react-bootstrap';
import { disableBodyScroll, enableBodyScroll, clearAllBodyScrollLocks } from 'body-scroll-lock';
class Header extends Component {
targetElement = null;
componentDidMount() {
this.targetElement = document.querySelector('.menu');
}
showTargetElement = () => {
if('.menu') {
disableBodyScroll(this.targetElement);
}
}
hideTargetElement = () => {
enableBodyScroll(this.targetElement);
}
componentWillUnmount() {
clearAllBodyScrollLocks();
}
render() {
return (
<div className="header">
<Navbar className="my-navbar" variant="dark" expand="lg">
<Navbar.Brand className="my-brand" href="#home">Karina Gaulin</Navbar.Brand>
<Navbar.Toggle aria-controls="basic-navbar-nav" />
<Navbar.Collapse
className="dropdown"
id="basic-navbar-nav"
>
<Nav className="mr-auto menu">
<Nav.Link href="#home">Home</Nav.Link>
<Nav.Link href="https://www.resume.com/share/karinagaulin" download>Resume</Nav.Link>
<Nav.Link href="mailto:karinagaulin@gmail.com">Connect</Nav.Link>
</Nav>
</Navbar.Collapse>
</Navbar>
</div>
);
}
}
export default Header;
