disabled

通过 Javascript 防止重复点击提交按钮，通常的做法是将按钮禁用通过 disabled 属性实现

jquery

$("form").submit(()=> {
  $(":submit", this).attr("disabled","disabled");
});

react

function App() {
  const [loading, setLoading] = useState(false);
  async function onSubmit() {
    setLoading(true);
    const res = await $ajax();
    if (res.code) {
      setLoading(false);
    }
  }
  return (
    <Form>
      <Button
        disabled={loading}
        type="primary"
        onClick={onSubmit}
      >提交</Button>
    </Form>
  );
}
