【问题描述】:
根据我的要求,当用户点击时
<Link to="/products/shoe#product9">Go to projects and focus id 9</Link> 我想向他展示产品。(你好页面)为此我这样做:
从“反应”导入反应; 从“react-router-dom”导入{链接、路由、切换、重定向};
import "./products.scss";
const Shoes = React.lazy(() => import("./shoes/shoes.component"));
const Cloths = React.lazy(() => import("./cloths/cloths.component"));
function hashScroll() {
alert("called");
const { hash } = window.location;
if (hash !== "") {
setTimeout(() => {
const id = hash.replace("#", "");
const element = document.getElementById(id);
if (element) element.scrollIntoView();
}, 0);
}
}
export default class Products extends React.Component {
render() {
return (
<div>
<header>
<Link to="/products/shoe">Shoes</Link>
<Link to="/products/cloths">Cloths</Link>
</header>
<h1>Products page</h1>
<main>
<Switch>
<Redirect exact from="/products" to="/products/shoe" />
<Route path="/products/shoe" onEnter={hashScroll}>
<Shoes />
</Route>
<Route path="/products/cloths">
<Cloths />
</Route>
</Switch>
</main>
</div>
);
}
}
我附加了一个onEnter 函数来调用和滚动。所以当有#hash 时让它滚动。但它根本不起作用。有人帮我吗?请导航到Hello页面,点击链接进入产品页面。

这能回答你的问题吗? onEnter not called in React-Router
-
只使用 ComponentDidMount 的副作用
