问题描述
根据我的要求,当用户点击
<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“react”导入React; import { Link,Route,Switch,Redirect } from "react-router-dom";
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,然后单击链接转到产品页面。
解决方法
nohup java -Xmx1024M -jar spigot.jar -o true > out.txt&
不再在 react-router 中工作
你可以做的是将一个 prop 传递给组件
onEnter
在 <Shoes onEnter={hashScroll} />
组件内在 Shoes
上执行它。
componentDidMount
