为什么在使用语义UI的搜索组件进行响应时，合成事件上没有`keyCode`值？

Question

I have created a simple Search with Semantic UI's Search Component like this:

<Search
    value={searchString}
    onSearchChange={onSearchChange}
    showNoResults={false}
    size="massive"
    placeholder="eg. Huberdo"
    input="text"
  />

This is my onSearchChange func:

const onSearchChange = (e, data) => {
console.log(e.keyCode);
if (e.keyCode === 13) {
  submit();
}
setSearchString(e.target.value);
};

Here is a minimum example of my problem. https://codesandbox.io/s/blue-leaf-7mzvo?fontsize=14

The Problem:

When I console log the event, I can't find any information about the keyCode that was pressed. e.keyCode is undefined as is e.charCode .

I need this so I can submit the search when the user hits enter.

Where is the keyCode hidden?

According to the Semantic UI Doc's the func gets passed in a normal synthetic react event. e.target.value is working as expected.

You can do this by adding an onKeyDown prop:

import React, { useState } from "react";
import ReactDOM from "react-dom";
import { Search } from "semantic-ui-react";

import "./styles.css";

function App() {
  const [searchString, setSearchString] = useState("");

  const handleEnter = e => {
    if (e.keyCode === 13) {
      submit();
    }
  };

  const onSearchChange = (e, data) => {
    setSearchString(e.target.value);
  };

  const submit = () => {
    console.log("submitted");
  };

  return (
    <Search
      value={searchString}
      onSearchChange={onSearchChange}
      showNoResults={false}
      size="massive"
      placeholder="eg. Huberdo"
      input="text"
      onKeyDown={handleEnter}
    />
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
