`useAsyncError`

从最近的 <Await> [await] 组件返回拒绝值。

jsx

import { useAsyncError, Await } from "react-router-dom";

function ErrorElement() {
  const error = useAsyncError();
  return (
    <p>Uh Oh, something went wrong! {error.message}</p>
  );
}

<Await
  resolve={promiseThatRejects}
  errorElement={<ErrorElement />}
/>;

import { useAsyncError, Await } from "react-router-dom";

function ErrorElement() {
  const error = useAsyncError();
  return (
    <p>Uh Oh, something went wrong! {error.message}</p>
  );
}

<Await
  resolve={promiseThatRejects}
  errorElement={<ErrorElement />}
/>;
