使用表格
一个常见的情况是处理表格的逻辑，可以为自定义钩提取
// form.tsx
import { formeventhandler, usestate } from "react";
function forms() {
const [title, settitle] = usestate("");
const [price, setprice] = usestate("");
const [description, setdescription] = usestate("");
const [image, setimage] = usestate("");
const [category, setcategory] = usestate("");
const [data, setdata] = usestate(null);
const [isloading, setisloading] = usestate(false);
const [error, seterror] = usestate(null);
const handlesubmit: formeventhandler = async (e) => {
try {
setisloading(true);
e.preventdefault();
const response = await fetch("https://fakestoreapi.com/products", {
method: "post",
body: json.stringify({
title,
price,
description,
image,
category,
}),
});
const data = await response.json();
setdata(data);
} catch (e) {
seterror(e);
} finally {
setisloading(false);
}
};
return (
