【问题描述】：
我正在尝试保存反应表单，然后更新一些用户设置。

import Dropdown from "components/Settings/Preferences/Dropdown";
import { useForm } from "react-hook-form";
function Pill({ value, handleChange,optionName,substanceKey,key }) {

export default InventoryPage;
目前点击提交时，表单本身只是刷新页面，并没有使用 onSubmit 常量。我不确定发生了什么，希望得到一些帮助:)
沙盒链接，代码正在编译，但可能更容易审查代码本身

【问题讨论】：
-
如果
<button>是一个普通的 html 标签而不是一个反应组件，它没有有效的variant属性。您尝试拦截按钮 onClick 事件并停止传播onClick={e => { e.stopPropagation(); e.preventDefault() } -
你能创建一个codesandbox吗？
-
@LeCoda，
onSubmit = (values, e) => {e.preventDefault();}怎么样？ -
不幸的是不起作用
